It has happened to every gamemaster. The soda sits on the desk, a bag of chips opened, SWRPGGM is open on your laptop and just as you the gamemaster opens your notebook, waiting for the next great inspiration to strike … nothing. No adventure, no world, no interesting characters. With your friends due to arrive in just a couple of hours you have drawn a blank.
That’s where the planet generation system comes in. The system allows gamemasters to roll up worlds leaving things to complete random chance and also gives comprehensive, detailed hints on how to construct exciting and fun planets. This section is filled with tips, comments and examples design to jumpstart a stalled imagination.
The planet generation system assumes that an interesting setting for an adventure is more important to the gamemaster than creating a “realistic”
distribution of worlds in a star system or use a world already found in the Star Wars Lexicon of Planets. It’s assumed that a gamemaster’s primary concern is to create a world that is interesting to visit the other planets in the system, the star type and so forth can be created by the gamemaster later if necessary.

Planet Generation System Explained
The planet generation system is designed to help gamemasters design exciting and fun new worlds for Star Wars: The Roleplaying Game. The system emphasizes the creation of unusual and memorable settings for roleplaying adventures, without requiring the gamemaster to generate reams of technical data.We hope it inspires great
new worlds for your adventures.
Ready To Begin
The gamemaster will need to use the Planet Template as a guide when creating their world. You might want to create a document or take hand notes on what kind of world it is that you have in mind as ideas come to your head.
The gamemaster can use the die charts found on this page to randomly generate worlds from scratch. Alternately, the gamemaster can use this rules section as a merely inspirational tool, using the descriptions and ideas herein as a baseline from which a comprehensive, detailed world emerges. The second method takes more time and
consideration, but is also more satisfying.
Keeping It A Star Wars Style Space Opera
When dealing with a science fiction roleplaying game, it’s very easy to spend too much time designing one planet. After all, from our own experience, Earth is a incredibly intricate and immensely interesting and the Star Wars galaxy has millions of stars with worlds equally diverse and fantastic.
However, the nature of Star Wars necessitates hopping to two, three, four or even more new planets in the course of an adventure. This system is designed to help gamemasters generate the most important and interesting details of a new planet, and makes a number of assumptions:
• The gamemaster will only want to send players to interesting planets and systems. The odds of this game system are heavily weighted toward generating advanced or colonized planets. The civilizations of the Star Wars universe have been spacefaring for so many centuries that most advanced civilizations (and a lot of primitive
ones as well) have been discovered and assimilated into galactic culture.
• There are isolated sections of the galaxy that offer undiscovered civilizations and other challenges, and they can also be generated with this system. They can exist for whatever reason: they are far out on the end of a spiral arm; or, they are difficult to get to because they are surrounded by gas clouds, near rogue planets or subjected to huge ion storms.
• Only the system’s planet of prime importance is fleshed out here. Other worlds can be developed independently, but virtually everything of interest and value is on the prime world.
• This system results in “finished concept” worlds, and doesn’t spend much time explaining how a particular planet got a certain way; it just is. An explanation of the culture and history takes a few minutes to formulate, but the results are worth it.
• Completely random rolls on these charts may generate seemingly contradictory results. The gamemaster always has the option of ignoring results that are unsuitable. However, knowing the diversity to be found in the Star Wars galaxy, virtually any result is explainable.
• This system generalizes the type of terrain found on the planets. While few worlds have uniform terrain everywhere, this system gives one or two dominant terrain types so the gamemaster can quickly sum up the planet.
• Optional modifiers listed after some results are just that: optional. The gamemaster has every right to fudge die rolls (or just arbitrarily decide upon a result). This system is only a tool for the gamemaster to create fun worlds; the gamemaster need not be subservient to a series of charts. All modifiers are cumulative.
• If an incompatible condition result is rolled, discard it and select a compatible result. It’s your story, tell it how you want it to be told.
This is where you place the Planet Name.
The following table determines the basic type of world that the civilization in question has developed on. Roll 2D and find the results below.
The planet is a typical ball of rock and metals orbiting a sun. Most terrestrial planets have atmospheres, and many have developed life. Move
on to the “Terrain” section below.
10: Satellite (Normally Gas Giant)
This world is a moon orbiting a gas giant (much like Yavin IV as seen in Star Wars: A New Hope). Since there is a civilization here, it probably
has a breathable atmosphere and supports life, or there were important resources too valuable to pass up. Satellites are almost always tide-locked to the gas giants they orbit.
11 : Asteroid Belt
Asteroid belts are either the remnants of planets shattered by collisions with large stellar bodies or merely portions of stellar material that
never coalesced into a planet. Settled asteroid belts are often rich in minerals and metals, and their small size prevents them from supporting
an atmosphere. Most asteroid belt civilizations are either subterranean or have sealed and probably domed buildings built on the surface. Since
asteroids are naturally airless, civilizations require regulated environments. Read the sidebar labeled “Regulated Environments” and then move
ahead to the section labeled “Starport.” Asteroid belt settlements required a tech level of atomic, information or space to be established (if the
settlement was abandoned, the civilization may have devolved and lost tech levels).
Optional Modifiers: -2 Population (initial roll only)
Incompatible Conditions: Agriculture, Homeworld Planet Function
Artificial results indicate orbiting space stations domed cities built on planets with toxic atmospheres, and great floating complexes built
in gas giants (such as Cloud City). All artificial settlements need some means of sustaining themselves (such as huge repulsor engines to keep
Cloud City aloft, or sealed domes to keep the toxins out of the city). Since artificial planets require a regulated environment, read the “Regulated
Environments” sidebar and then skip to the section labeled “Starport.” Artificial settlements require a tech level of information or space.
Optional Modifiers: -2 Population (initial roll only)
This classification represents the average temperature on the planet’s surface. Most planets have several varying temperature bands, from the coldest (polar regions) to warmest (equatorial region). The “true” temperature of an area can be altered by local geographic features. Seasonal changes also greatly alter temperature (see “Seasonal Changes” sidebar). Some planets are trapped in what is called tide lock (see “Tide Lock” sidebar). Still other planets have elliptical orbits (see “Elliptical Orbits” sidebar).
All of these possible combinations give the gamemaster a great deal of diversity and choice when designing the planet. These special results are not incorporated into the random tables so that the gamemaster can choose exactly which effects are most useful. Roll 2D to determine the average temperature.
Searing planets average 60 degrees Celsius or more, and are hostile to most life forms, although standing bodies of water are possible as long as the average temperature isn’t near the boiling point (100 degrees Celsius). Most civilizations will tend to cluster near the more moderate polar regions or underground.
Hot planets average between 30 and 56 degrees Celsius, and while generally uncomfortable, are not nearly as hostile as searing planets.
Temperate planets average between -5 and 29 degrees Celsius, and are in the most comfortable temperature bands for Humans and other life
Cool planets average between -20 and -4 degrees Celsius. Most cool planets do not support a huge number of life forms, but life can still adapt
to planetary conditions. Plant life may be common if it contains compounds that prevents vital water-based fluids from freezing.
Frigid planets average -21 degrees Celsius or less, and are often inhospitable. If the hydrosphere is Temperate, Moist, or Saturated, the planet may be covered with ice glaciers.
Most stellar bodies of significant size have atmospheres (some planets have had their atmospheres ripped away by a near pass with a rogue planet or some similar cataclysm). Gas giant atmospheres are often composed of methane, ammonia, and various hydrocarbons (Type IV), although a very small number of gas giants have been discovered with a breathable atmosphere within a limited biozone (Bespin being the prime example). Imperial bureaucrats use a very simple classification system for atmospheres. Most ship sensors can determine the type of atmosphere with sensors. However, sensors are not perfect, and may miss trace elements that can be harmful to the ship’s inhabitants, so the results of a sensor scan should never be taken at face value. To randomly determine a planet’s atmosphere, roll 2D and check the result below.
This planet has no appreciable atmosphere and a space suit is required simply to survive on the world. Planets without an atmosphere typically have much greater temperature variations because there is no atmosphere to disperse solar energy (on the sun side) or retain heat (on the night side). Characters exposed to the vacuum of space suffer 4D damage the first round of exposure, and increase the damage by +2D for each additional round in the vacuum.
2-9: Type I (Breathable)
A Type I atmosphere has a proper mixture of oxygen, nitrogen and other gases so that Humans and comparable species can breath it unassisted. These atmospheres may have contaminants that over the long term have a detrimental effect.
Planets with a Type I atmosphere will have life or at least had life recently.
10: Type II (Breath Mask Suggested)
Type II atmospheres can support life without use of a breath mask, but either due to too much or too little atmospheric pressure or oxygen, or unusual gases or contaminants, it is recommended that a breath mask be worn. Without a breath mask, detrimental effects, such as slowed reactions, reduced brain activity, poisoning, or a myriad of other effects can begin to occur within just a few hours of exposure. Many alien species can comfortably breathe Type II atmospheres without having to resort to breath masks.
Planets with a Type II atmosphere will have life or at least had life recently.
11: Type III (Breath Mask Required)
Type III atmospheres are unbreathable without a breath mask, again due to a number of possible characteristics. The atmosphere could be highly poisonous, or simply not have enough oxygen to breathe. Characters without breath masks can begin to suffer detrimental effects immediately. A small number of alien species (and certainly native creatures) will be able to breath these atmospheres unaided.
Type III atmosphere planets frequently support life.
12: Type IV (Environment Suit Required)
Type IV atmospheres are not only poisonous, but they are so reactive that they will cause injury to persons who are exposed to it. Environment suits, space suits or life-support equipment is required to venture through the atmosphere, or characters will suffer burns and other grievous injuries. If the planet is Frigid, a thermal suit may be necessary. These atmospheres may also be flammable or highly explosive. The gamemaster must customize the effects of the hostile atmosphere.
The hydrosphere represents the amount of moisture on or near the surface of the planet. Water is not necessarily the only liquid that can be found. The water may have a high concentration of another substance that makes it unfit for consumption, or the liquid might merely be water based, but have other components that make it a different compound. More exotic options include huge lava lakes (on planets with plenty of geologic activity), or deadly ammonia seas (on extremely cold planets). Roll 2D.
The planet is 85-100 percent covered by land. The planet has very little or no standing liquid, and there probably is very little moisture in the atmosphere. There may be large lakes and seas, but there are no great oceans. Much of the planet will probably be desert.
The planet is 50-84 percent covered by land. The planet has some standing liquid, and the land is probably a mixture of desert, dry plains, tundra, or other terrain types not requiring a great deal of water.
The planet is 15-49 percent covered by land. The planet has large oceans and probably a well developed river network, especially if the planet has large hills and mountains. There are probably many different terrain types.
The planet is only 5-14 percent covered by land. Most of the planet is covered by water or another liquid, and the few land masses that do exist are wet. Bogs and swamps are common.
The planet is only 0-4 percent covered by land. Land only takes the form of islands, which may again be bogs, or swamps. Oceans dominate the
Star Wars: The Roleplaying Game uses four classifications to indicate the gravity of a world. As indicated before, most regulated environments
will have a gravity of Standard.
Asteroids, comets and other very small stellar bodies have effectively zero gravity, which also eliminates the possibility of an atmosphere (barring the use of technology, such as energy screens). Space stations that lose power may also lose their repulsorgrav generators, effectively throwing the whole station into a zero gravity situation.
In zero gravity, things and beings float unless thrust is somehow provided. On the other hand, once something begins moving, it doesn’t stop until something else stops it (such as a collision with a wall). The applies for vertical, horizontal and even twisting movement since there truly is no “up” or “down.”
Characters in zero gravity can float up to five meters per round and have no control over direction unless they have something to push off against, in which case they float 10 meters. Increase the difficulty of all Dexterity or Strength checks by 2 (excluding checks to resist damage). Combined actions are not possible. Characters attempting full dodges will smash into any object in their path (taking 3D stun damage). Each dodge counts as two actions. Characters will be able to control their direction of flight by firing blasters or projectile weapons as a means of propulsion, but this requires a Moderate Mechanical roll to control direction. Similarly, characters who fire weapons in combat will be pushed away unless they are braced against a wall.
Planets with light gravity allow characters to lift heavier objects, but also throws off physical coordination. They also allow easier movement. There are few inhabited planets with light gravity.
In very light gravities, the gamemaster may want to use the following optional modifiers: + 1D bonus to all Strength actions (except for resisting damage); -1D penalty for all Dexterity actions. Optional Modifiers: +2 Atmosphere
Standard gravity is that which is most common on Imperial worlds, and therefore most comfortable for most species. Standard gravity includes several gradients of true gravitational pull, but is placed within this convenient grouping.
Heavy gravity planets have a much stronger pull than normal, the effects of which can be merely inconvenient or crippling. Planets with very heavy gravity may make a person’s body so heavy that they cannot move. There are few planets with heavy gravity, and most of them are just barely beyond the Standard gravity classification. On these “barely heavy” gravity planets, even walking counts as an action (it is not “free movement”).
Gamemasters can use the following optional modifiers for slightly heavier gravity planets:-1D to all Strength and Dexterity actions (except for resisting damage). Characters must make a minimum of a Moderate stamina check after every minute of heavy exertion, although checks may be made more difficult or frequent at the gamemaster’s discretion. Characters who fail these stamina checks must rest for a double the amount of time they were active or suffer a -3D penalty to all actions except resisting damage in combat. Additionally, when the character suffers damage from collisions or falling, increase the damage by a minimum of 1D.
Optional Modifiers: +2 Atmosphere
The gamemaster must determine the dominant terrain for the planet. There can be many different types of terrain on a planet, but the dominant terrain is the one that the characters will interact with most often. Diverse planets may have several major terrain types. Additionally, the planet’s terrain may be a combination of types (such as mountainous forest).
While these classifications provide basic information as to the terrain types, the gamemaster must customize them to match the unique nature of the planet. Each terrain entry has a listing of compatible conditions, which is where these terrain types are most likely to be found. Some terrain types also have incompatible conditions, where they will seldom be found. If a quality isn’t listed (such as a Moderate Hydrosphere, for example), the conditions are neither particularly favorable for the terrain, nor do they preclude the existence of the terrain type. If the gamemaster rolls incompatible terrain results, he may opt to discard the results, or reason through a really unusual situation that allows this result (this is the most entertaining option).
To determine the terrain type, roll on the six sided percentile system.
Barren planets are typically Arid, possibly with hostile atmospheres. The ground is extremely hard, dry and is hostile to most forms of life. There may be large rocks on the surface or embedded in the rock hard ground. Minerals and metals may be found. Barren planets are predisposed to unbreathable atmospheres.
Compatible Conditions: Arid, Dry Hydrosphere
Incompatible Conditions: Moist, Saturated Hydrosphere
Optional Modifiers: -2 Population (initial roll only); +3 Atmosphere
The planet is dominated by an immense network of caves running throughout the crust. These caves are often caused by volcanic activity, and if the activity is ongoing, areas can quickly become dangerous as lava and toxic gases return to fill the caves they created. Cave planets almost always have Type 11 atmospheres.
Optional Modifiers: +2 Atmosphere; -2 Population (initial roll only)
14: Crater Field
Crater fields can occur in virtually any other type of terrain, and they are the result of continuous impacts from meteorites, resulting in huge cratered areas on the planet. The impacts could have ended millions of years ago, or they may still be ongoing. Large enough meteors could cause significant climate changes on a planet by throwing huge clouds of soil into the air or causing earthquakes. Planets with light gravities are favorable for crater fields. .
Incompatible Conditions: Thick atmospheres
Deserts are typically found on dry and arid planets, and support only a minimum of life due to a lack of moisture. Deserts can be found in any temperature zone. Warm desert areas can be very dangerous because travelers can easily become dehydrated (an exposure suit will prevent dehydration).
Compatible Conditions: Arid, Dry Hydrosphere
Incompatible Conditions: Moist, Saturated Hydrosphere
Forests occur most commonly in temperate zones, but they can also occur in very cold or warm areas. If they receive a great deal of precipitation in tropical areas, they are called rain forests. Forests may be active year round, or may be seasonal (most of the plants go into hibernation during cooler seasons). They generally receive ample rainfall.
Compatible Conditions: Moderate, Moist Hydrosphere; Hot, Temperate, Cool Temperature
Incompatible Conditions: Arid Hydrosphere; Frigid, Searing Temperature
Glaciers are huge, frozen sheets of ice that can be several kilometers thick. Icebergs are chunks of glaciers that have been broken off and now float in oceans. Glaciers grind the land beneath them, constantly reforming it. Glaciers can occur on land, or above ocean.
Compatible Conditions: Moist, Saturated Hydrosphere; Cool, Frigid Temperature
Incompatible Conditions: Arid, Dry Hydrosphere; Searing, Hot, Temperate Temperature
Jungles are any area overgrown by plant life, and often include low-lying wetlands that support many forms of plant and animal life. They are often warm at least a substantial portion of the local year. The ground can be moist or dry. They are excellent incubators for life, from plants to insects and animals. They require ample water, but can be warm or cool.
Compatible Conditions: Moderate, Moist, Saturated Hydrosphere; Searing, Hot, Temperate Temperature
Incompatible Conditions: Arid, Dry Hydrosphere; Cool, Frigid Temperature.
Mountainous planets have been (or still are) home to a great deal of geologic activity. The mountains can range from small hills (under a kilometer tall) to huge peaks several kilometers tall. Depending upon the planet’s atmosphere, plant life, and soil, mountain areas can support a variety of plant forms from trees to grasses. Peaks of mountains on temperate and cold planets may be snow capped. Snow capped mountains can be quite dangerous because of avalanches.
Incompatible Conditions: Saturated Hydrosphere
Ocean planets are dominated by huge bodies of water or other liquid. The oceans can be very deep, or merely large and shallow, depending upon whether or not geologic activity has created great mountainous regions (islands are often the peaks of small mountains that emanate from the ocean’s floor). These planets may be searing to frigid, although frigid oceans will often be covered by huge glacial sheets of ice.
Compatible Conditions: Moderate, Moist, Saturated Hydrosphere
Incompatible Conditions: Arid, Dry Hydrosphere
Optional Modifiers: -I Population (initial roll only)
Plains areas are simply huge, flat expanses of life, typically supporting grasses and bushes as primary forms of plant life. Grasslands can be found in virtually any hydrosphere and temperature range, butthey are most common in tropical and temperate dry regions. Very cold, dry grasslands are often called tundra, and very warm, dry grasslands are often called savannahs.
Compatible Conditions: Dry, Moderate, Moist Hydrosphere; Hot, Temperate, Cool Temperature
Incompatible Conditions: Arid, Saturated Hydrosphere; Searing, Frigid Temperature
Plateaus are large sections of mostly flatland that are elevated above other portions of nearby and. They typically occur in the interior of continents. On a plateau, virtually any type of terrain can be found.
Incompatible Conditions: Saturated Hydrosphere
This result means that most of the planet is covered by artificial constructions, typically huge city sprawls. This is indicative of a very high population, and most so-called urban planets concentrate on trade, manufacturing or administration. Agriculture can sometimes be conducted in huge hydroponics factories, or beneath the surface if the plants don’t require sunlight (typical of mosses and fungi). Urban terrains can be layered on top of most other terrain conditions, such as plateaus, mountains, and plains. In addition to habitable cities, urban results may indicate huge factories and relining facilities.
Aside from buildings, many urban settings will have extensive cultivated areas for agriculture. This classification can include any developed area that isn’t wilderness.
Optional Modifiers: +1 Population (initial roll only)
Wetlands are moist low-lying wet areas, and playa vital role in most eco-systems. They can take the form of ponds, marshes, or swamps, and support bushes, trees, grasses and many different forms of life.
Incompatible Conditions: Arid, Dry Hydrosphere; Frigid, Searing Temperature
Volcanoes and lava pools cover the planet, indicating a very high level of geologic activity. Volcanic planets often have high levels of ash and toxic gases in the atmosphere, and the lava, of course, is very dangerous. However, these planets often have high quality metals in their crust. Volcanic planets often have hazardous atmospheres.
Incompatible Conditions: Type I atmospheres Optional Modifiers: -2 Population (initial roll only); +3 Atmosphere
64-66: Special Terrain
These are unusual terrains that demonstrate the incredible versatility of the Star Wars universe. These terrain types can also explain seemingly contradictory terrain rolls. What follows are some examples:
• Crystal forests and fields. The crystals may be immensely valuable, or merely scenic. They may also be a hazard if they magnify incoming sunlight, possibly blinding careless travelers.
• Planets with ammonia oceans, where the land masses are actually rock-solid ice fields. This type of condition requires very low temperatures and often has a Type IV atmosphere.
• Underground forests, found in great subterranean caverns. The trees and bushes derive most of their energy from the geothermal energy released by the interior of the planet.
• Huge canyons cover the planet like on Arvala-7.
• A planet where most of the water is trapped on high plateaus, and the lowest sections of the planet are actually parched deserts.
• Planets like Kashyyyk, with several distinct “bio-levels,” where the type of creature and its behaviors is distinctly different based on the altitude. This can be accomplished through use of mountains, huge trees, or even planets where there are many lighter than air gases and many flying and gliding creatures have internal bladders for constant lift.
• Planets that are covered with toxic and radioactive pools. They may have been mining planets that were just tapped out and converted to waste dumps. Whole new Iifeforms (and hardy ones at that) could evolve in these conditions.
• A planet with an unusual substance that mixes with water, turning into a jellied goo at temperatures up to 80 degrees Celsius. In warmer seasons, there are huge flowing oceans of the muck, while in winter, the goo hardens, expands and covers much of the planet (much like a hot-weather glacier).
Length of Day
The length of day for most terrestrial planets not subjected to tide lock or another extreme condition is in the range of 18 to 36 standard hours. Even though tide-locked planets do not have days, it is useful to determine what a likely day length would be so that the length of the local year can be determined. To determine this total, roll 10:
• If the result is 1-2, roll 20 and it to 10 for a total number of hours.
• If the result is 34, roll 10 and add it to 20 for a total number of hours.
• lf the result is 5, roll 10 and add it to 25 for a total number of hours.
• lf the result is 6, roll 10 and add it to 30 for a total number of hours.
Satellite planets may have days several dozen hours long (as long as it takes the satellite to orbit the gas giant). The local year depends upon the orbit of the gas giant and may be several standard years long.
Length of Year
A simple die roll will generate a suitable total since so many different factors are responsible for the determining the orbital radius and speed of the planet. The total can be increased or decreased by a few days to make the total unique compared to other planets.
To determine this total, roll 20 of different colors. Read the results below and the total of the two numbers equals the length of year in local days:
First Die: Multiply the number x15
|1||75 local days|
|2||150 local days|
|3-4||225 local days|
|5||300 local days|
375 local days
The gamemaster should determine what alien species are on the planet in large quantities. Humans are among the most diverse species in the galaxy and can be found almost everywhere, but other species such as Oevaronians, Ouros, Gamorreans, Ithorians, Rodians, Sullustans, and Twi’leks are also known to colonize and reside on many different planets. If the planet is similar to a species preferred climate, or there is plenty of work to be found, other species may be encountered as well. The planet may have a native sentient species, designated by an (N) on this line of the planet template.
Gamemasters must take a few moments to design the native sentient species, bearing in mind the kind of environment the species evolved in. He should decide their biology, culture, history, how galactic civilization changed their society, what common occupations they have and what their personalities are like.
The Imperial Space Ministry has five different classifications for starports. For random determination of the starport, roll 20 and find the result on the chart below.
2: Landing Field
There may be a flat space on the ground for ships to land. There is no control tower (there may not even be other starships on the planet). Fueling and repair services are probably unavailable at any price.
3-5: Limited Services
This is typically a simple landing field, but there is at least a control tower to prevent collisions between ships in the planet’s airspace. There may be maintenance sheds for rent. There may be fuel for sale, but other important supplies are unavailable.
6-8: Standard Class
The starport is fully-staffed and equipped. Restocking services are available, and there is a small shipyard for minor repairs and modifications. Prices for repairs and modifications can be up to double normal prices, and take twice as long to accomplish.
9-11 : Stellar Class
This type of starport can dock and service almost any class of ship. There are probably several shipyards in the immediate area, and they can handle major repairs and modifications. There is almost always an Imperial Customs office on site.
12: Imperial Class
Modern and luxurious ports with complete storage and maintenance facilities, and a large number of landing fields and docks. A complete menu of services and luxuries are available for the ship and its crew. Important merchants have offices at the starport. The shipyards are capable of rapid repairs and modifications. The Imperial Customs office is well staffed.
For more information on starports, see our Starport and Space Station Guide.
This figure represents the total sentient population on a particular planet. For random determination, roll 10 and use the chart below.
|1||Population is 1-999|
|2-3||Population is in the thousands|
|4-5||Population is in the millions|
|6||Population is in the billions|
Once the basic range is established, roll 10 to determine whether the population is in single numbers, tens or hundreds for that category
|1-2||Population is in singles (1-9)|
|3-4||Population is in tens (10-90)|
|5-6||Population is in hundreds (100-900)|
To determine the exact number, roll 10 to determine if the number is 1-5 or 6-9. It is recommended that the population only be determined for two significant figures (Le., only roll the first two numbers).
|1-3||Number is between 1-5 (roll 10, ignoring 6)|
|4-6||Number is between 6-9 (Roll 10, ignoring 5 and 6, and add five)|
It is recommended that the gamemaster not allow populations over 100 billion. Any population over 10 billion is very likely to be an urban terrain planet, with a standard class or better starport and an industrial level or higher tech level.
Example: The gamemaster wants to randomly determine the population of a planet. He rolls 10 getting a result of “3” (the population will be in the thousands).
A second die roll yields a result of “5” (the population is in the hundreds of thousands).
To determine the exact number, the gamemaster must first roll the first significant figure. A roll of”1″ tells him the number is between I and 5, and a second roll of “3” tells him the first number is 3, for a first number of 300,000.
To determine the second significant figure, a roll of “5” tells him the number is between 6and 10. To get the specific number, he rolls 10 and adds five, ignoring a 5 or 6. He rolls a “1”, and by adding 5, gets a total of 6.
This makes the planet’s population 360,000.
Since Star Wars is space opera, and leans heavily toward action and strong story telling, the most important aspect to players is what can be found or explored on the planet. The following results give some indication as to what types of industries and activities are common on a particular planet. For greater diversity, the gamemaster may roll on this chart multiple times.
To determine the planet function, roll two six sided dice. Read each number separately (this is a six-sided percentile system; do not add them together for a total). This generates totals between 11 and 66.lt is best to use two different color dice (say, red and blue), reading one color die before the other. For example, if you’re reading the red die first, and you roll a “3” on the red die and a “2” on the blue die, your roll is a “32” (Homeworld planet).
11 : Abandoned Colony
This is a planet that was settled by another planet, a company or some other wealthy instituion. Then, for some reason, the colony was left behind: the homeworld could have been struck by plague or war, or the company could have run out of money. The planet might have been evacuated (only leaving ruins), or supply ships just never arrived, in which case the colonists were on their own: they may have devolved into barbarism and anarchy.
Educational institutions are what is most important to the economy of this planet. Academic worlds typically have many universities and colleges, which may be private, corporate or state run.
Options for low tech level worlds are varied: the university was purposefully established to remove students from the temptations of modern comforts. Or, the natives may have had some contact with free-traders, and have committed all of their efforts to unlocking the secrets of modern technology.
This result doesn’t necessarily mean academic work towards a degree. Tradeschools, institutions dedicated to unlocking the secrets of the Force (these will always be well hidden since the Emperor has made it a priority to kill Force users), and survival schools are possible options.
Optional Modifiers: +1Starport; +1Tech Level
This world is bureaucracy at its largest. The main industry is the orderly (or at least managed) operation of a government, business, or other large institution. Imperial sector capitals often qualify for this designation, but the homeworlds of major, galaxy-spanning corporations and institutions such as BoSS (Bureaus of Ships and Services) may also be considered administrative in nature. Low tech level planets could also be administrative, especially if the economy is directed entirely by the government.
Optional Modifiers: +1 Starport; +1Tech Level
14-21 : Agriculture
This planet is dedicated to the production of food. The types of products can include grains, vegetables, fruits, meats, vitamins, dietary supplements, and water. Many ocean planets also rely on agriculture, through fishing or algae and vitamin farms.
Incompatible Conditions: Asteroid Belt, Artificial Planet Type; Barren Terrain
This planet has been established and sponsored by another, more developed planet or corporation. Colonies are generally dependent upon the sponsor for supplies, and typically are subservient to its dictates. Colony worlds aren’t independent entities, although there may be a separatist movement. Colony planets generally produce goods onlyfor consumption bythe sponsor, and thus are often prevented from developing a self-sufficient economy or acquiring significant wealth. Many colonies are devoted to agriculture and mining.
Disaster planets have gone through cataclysmic changes that have dramatically altered the world’s history. The event could have been a war that used atomic weapons, a plague, an industrial accident, a collision with a large stellar body (such as an asteroid) or a dramatic change in the nature of the system’s star (such as when stars balloon into red giants, incinerating all of the inner planets and drastically changing the climate of the surviving worlds).
The disaster could have occurred just a few years ago (generally making the world very dangerous), or it could have happened decades or eons ago (in which case the danger from the actual disaster may have passed, but the aftermath could be devastating).
Optional Modifiers: Of recent calamity) -3 Starport; -2 Tech Level; +3 Atmosphere
This planet’s business is show business. Holovids, musical groups and the businesses that distribute their works to the general public are dominant here. Some planets specialize in sporting events (such as swoop races), amusement parks, gambling or tourism.
This planet, and the whole system for that matter, has seldom been visited, until now, when the characters have arrived. Exploration planets tend to have primitive technology levels (if there are even sentient species). There are few urban areas, with the emphasis on dangerous wilderness. Lost artifacts from past ages may be on these planets, or there may simply be wandering tribes of aliens who are eager to trade. These planets may be rich in natural resources.
There may be some hint of galactic civilization in these systems, or on the planet in question perhaps a secretive trader has retired here, or fugitives may be hiding from the Empire. These locales are excellent for hidden bases, or if nearimportant trade routes, may be a convenient stopover for independent traders.

31: Hidden Base
There is a base on this planet that someone wants to keep a secret. This immediately sets up a conflict for the characters, since that someone will probably hunt them down to prevent anyone else from finding out about the base. Alliance and pirate bases are logical choices. Other options may include the Imperial military or corporate interests (possibly a weapons or biological engineering research facility). Wealthy individuals may have a private hideaway.
This result means the planet is a homeworld for an established alien species. It could be Calamari (home of the Mon Calamari and the Quarren), Sullust (home of the Sullustans), or one of thousands of other homeworlds throughout the galaxy. Most of these planets have modern starports, a sophisticated trader network and a high level of technology. Almost all homeworlds of atomic tech level or higher have already been subdued by the Empire unless the characters are in unexplored regions of space.
34: Luxury Goods
The planet produces luxury goods, such as liquor, finished gemstones (such as the Garnib crystals), spices, art or other goods. This planet may be self-sufficient, or may be devoted exclusively to producing the luxury good (which would requiring importing everything else).
The inhabitants of this planet devote most of their time to manufacturing goods. The goods generally fit into three distinct categories: low tech, mid tech, and high tech. These goods may be for consumption by the planet’s own residents, or they may be for export to other planets. They may be finished items, which are shipped directly to markets, or the planet may be an intermediary step, whereby the planet takes in raw materials from one planet, and then processes the material so that it can be used in the production of a finished good, which is manufactured someplace else.
Low tech items are simple manufactured goods, such as handiworks, native crafts, furniture, basic medicines and woven cloth. The goods may be mass produced in factories, or may be made individually by skilled craftsmen
More complex items are produced on this planet. Textiles, mechanical weaponry (projectile weapons), pharmaceuticals, paper goods, vehicles, and primitive versions of high tech goods, such as computers and plastics, can be manufactured on these planets. Assembly line factories are frequently necessary to produce these goods.
Modern computers, blaster weapons, superhard plastics and alloys like transparisteel, polymers, chemicals, bioengineered life forms, advanced bio-immunal medicines, cybernetics, medical equipment, droids, vehicles and starships are all considered high tech goods. high tech goods almost always require advanced manufacturing methods.
Optional Modifiers: Mid tech Planets: +2 Starport; +2 Tech Level. High tech Planets: +3 Starport; +4 Tech Level
This planet is an important Imperial military facility. It has one or several large bases. Sector capitals, planets near strategic trade routes, Imperial ship yards, and weapons manufacturing planets have huge military bases.
Optional Modifiers: +3Starport; +2Tech Level
Mining planets depend upon the minerals and metals iocked beneath the ground. These planets truly drive the Imperial economy, because without the raw materials there would be no starships or vehicles. Blaster gases are also mined, but are taken from gas giants (such as the Tibanna gas mine on Bespin).
Optional Modifiers: +2Starport; +1Tech Level
51-55: Natural Resources
These planets utilize naturally occurring resources such as wood (for logging), animal skins, and glaciers (“harvested” for fresh water). Other products that could be harvested are raw materials for medicines and pharmaceuticals, and may be either plant or animal derived. This category differs from agriculture because the products aren’t food.
These planets are used for scientific and academic research. The world may have abundant resources, but the particular company or university may have an exclusive charter and is allowed to decide who develops the planet. Research may be for purelyscientific oracademic knowledge, but other planets, like Gorsh, are studied for new chemical compounds with practical applications.
Service planets tend to have a multi-classed social system and great wealth. The exclusive higher classes have control over the wealth and resources, and the lower classes provide services and goods to the wealthier individuals. Service planets tend toward direct sale to consumers, or may be devoted to banking, legal services, medical services, or financial markets.
Optional Modifiers: +1Starport; +2 Tech Level
Aplanet with a subsistence economy is working hard just to survive. There is little to send to other worlds to generate income, and if the planet has to import many goods, the debt could be staggering. Another option is a planet that depended upon one product which has lost a great deal of Its value, and as a result, unemployment and poverty have grown dramatically in recent times.
Trade planets tend to be the most active and exciting planets in the Star Wars galaxy. They are blessed with being on a good trade route, and as a result, everyone stops here to sell goods, make deals and purchase goods for resale at other locations. Sector capitals, planets that produce manydifferent products and planets with wealthy populations are often trade planets.
Optional Modifiers: +3Starport; +2Tech Level
Government is the means by which a society determines what is permissible and what is forbidden. Governments can regulate business or corporate behavior, or even eliminate entities such as businesses. They can severely curb a citizen’s rights, or be very permissive.
The following results determine what type of government has been established on this planet, but it is up to the gamemaster to determine what the government in question believes in – these categories simply detail by what means the government operates. If the gamemaster wishes to generate more variety, roll on this chart multiple times to determine secondarygovernments or to determine a strong influence within the prime system of government.
One thing to remember is that most planets in the galaxy are under the firm control of the Empire. This chart assumes that the planet is under Imperial control (with the notable exception of the Rebel Alliance result), although many primitive planets (feudal or stone tech levels) have been left alone simply because they offer too few resources or tax revenues to be worth the effort.
Most Imperial planets have been allowed to retain their traditional form of government, but all Imperial worlds have troops and equipment deployed to help the local population remember who is in control of the situation. Many, but not all, planets have Imperial governors who act as liaison between the Empire and the planetary government. On some worlds, the governor has assumed control (an action well within his or her authority). Particularly troublesome worlds are often subdued by Imperial military crackdowns.
To determine the government type, use the sixsided percentile system. This generates totals between 11 and 66. It is best to use two different color dice, reading one color die before the other. For example, if you’re reading the red die first, and you roll a “5” on the red die and a “6” on the blue die, your roll is a “56” (Representative Democracy).
Several different groups (tribes, nation-states, corporations or whatever else – you decide) have formed an alliance. The degree of cooperation and the vitality of the alliance differs from situation to situation. Typical purposes for alliance include an improved economy, mutual defense, or the arrival of a situation so compelling that the different groups can put aside their problems to accomplish “a greater good.” Betrayal is always a possibility, especially if there are other competing alliances.
Anarchists stand for the individual and his or her rights above all else, including government. Anarchist governments could conceivably be quite elaborate, but would exist only to insure that each individual has complete freedom.
Anarchism is commonly perceived as a lack of law and order, and on many planets, that is indeed the truth.
13-16: Competing States
Several nation-states, tribes or corporations are actively competing for control of the planet. The intensity and type of competition varies, and can range from economic competition to open war.
21-22: Corporate Owned
This planet is owned by a corporation, trade guild or other large business interest. Most of these planets produce goods for use or resale by the parent corporation. Other corporate planets are for the pleasure and relaxation of the executives and employees – in essence, giant recreation planets. Residents are almost always employees of the corporation, and have strict guidelines and rules to follow, such as having to pay rent on corporate housing, or being required to purchase goods only from corporate retailers. The corporation is allowed to do whatever it likes (with the agreement of the Empire, of course). Conditions on planets are widely variable, from harsh and repressive to agreeable and comfortable.
Optional Modifiers: +3 Spaceport; +2 Tech Level
Dictatorships are commanded by a single individual, such as a charismatic military officer, or an insane politician who will execute anyone. Dictatorships are almost always repressive and intolerant of divergent political, philosophical and social views.
The most important social organization on the planet is the family. There are a variety of possible scenarios, including a pre-tribal state, where families have little or no technology and constantly engage in warfare with each other. At higher tech levels, a small group of elite families could control the government, either overtly or through behind the scenes manipulation of the government in power.
A multi-structured social system, in which important officials (nobles or royalty) are entrusted with a specific area of land. They must manage the territory, provide tax revenues to higher-level officials and make sure that the commands of these higher-level officials are carried out.

32: Guild/Professional Organizations
The planet is controlled by a guild dedicated to the advancement of a particular occupation or philosophy. Many trade planets are run by trade guilds (see Celanon). These guilds may also control certain portions of the government, and subtly direct the kind of legislation and decisions that are made.
33-42: Imperial Governor
This is a planet where the designated Imperial governor has taken control, either due to civil unrest, sheer ego, or belief that the previous government was inept, disloyal or unresponsive.
Military planets are controlled by either the Imperial military or a local military organization. They tend to have governments which perpetuate only the military structure, ignoring the needs and desires of the civilian populations – martial law is a way of life. Harsh, brutal crackdowns can occur with only minor provocation. Civil rights take a low priority when compared to accomplishing government goals.
A type of government where absolute authority is granted to one individual, often called a king or queen. The leadership position is normally granted by heredity. Planets may have patriarchal (only male rulers) or matriarchal (only female rulers) societies.
53: Organized Crime
Aplanetary or galaxy-wide criminal organization has established a government loyal to the criminal leaders. Organized crime planets are typically run so that only those who are unswervingly loyal to the criminal organization receive advancement and promotions; opponents are simply eliminated.
Organized crime may also covertly control a government by bribing or blackmailing officials, or threatening their families. These governments are typically oppressive.
54: Participatory Democracy
Citizens vote directly on Important issues (some advanced planets have citizens vote on virtually every proposed bill).
55: Rebel Alliance
Agovernment that supports the Rebel Alliance and its objectives. Few planets can risk openly supporting the Alliance (Alderaan is a painful example of what happens to openly rebellious worlds), but several planets secretly shuttle funds to Rebellion coffers, or offer safe passage for Rebel agents, supplies and weaponry. Hidden Rebel safe worlds also qualify for this designation.
56: Representative Democracy
Planets with a representative democracy have citizens choose officials, who are then charged with representing the “public interest.” These type of governments can experience radical shifts in goals and policy if the population is unsatisfied with performance and threatens to remove the representatives from office.
61: Ruler by Selection/Rite
The ruler is chosen by a series of trials, physical, mental or both. While these governments are often found on more primitive planets, advanced civilizations may use complex testing methods to determine who is most fit to govern a planet, nation or locality.
Agovernment run by a religious organization. Typically, the citizens are required to participate in certain religious rites and profess faith in the tenets of the religion. Theocracies may be highly tolerant of divergent views, but some are also quite repressive.
Tribal governments seldom control more than a small portion of the planet. Tribes are groups of many families who have banded together for mutual survival, or who sharecommon beliefs. Tribes are often precursors to city-states and nation-state governments, but many highly advanced and sophisticated tribal governments are found on planets throughout the Star Wars universe. Tribes can be nomadic, depending almost entirelyupon hunting and foraging for food, or they can settle, which indicates the development of agriculture.
The level of technological achievement is important in determining what goods the planet can manufacture, as well as what they are likely to be interested in purchasing. Few planets fit directly into one of these classifications.
This classification system, utilized by Imperial bureaucrats, represents the typical level of technology to be found on the planet, but there may be areas where individuals have developed or somehow acquired more advanced technology. Planets with no sentient inhabitants are considered Stone level by default. Roll 20.
Stone level civilizations have loosely-knit cultures and the basic social unit is likely to be the tribe. The society makes and uses stone tools and may have developed primitive agriculture. These people do not understand the concept of money, so trade will be by barter. There is no transportation network.
Feudal planets have a more complex social structure and have begun to produce primitive manufactured goods. They have learned primitive mining and ore-processing techniques. Transportation is normally by ship or caravan.
Industrial planets are beginning to understand mass production, and have established more complex political and social structures. Windmills, waterwheels, wood or coal furnaces will be used to generate energy. These planets typically want to acquire knowledge to help improve their technology. Motorized transportation, projectile weapons and the beginnings of mass communication are common.
Atomic planets have advanced, large-scale production of goods. They will be very interested in new technologies. More advanced alloys and plastics become available. Space travel is in its infancy. Established industries, such as transportation, communications, medicine, and business, quickly progress and grow.
Sophisticated communications, such as computers and satellites, become readily available. Industry becomes more efficient, mechanization is very common, and the precursors of droids appear. Energy weapons are beginning to be discovered, in-system space travel is common and colony ships to other planets are a distinct possibility. Repulsorlift may be developed. Natural resources may become scarce.
This is the stage of most planets within galactic civilization, and is characterized by hyperspace travel, droids, blasters, and highly efficient industry. Planets at this level are often integrated into the galactic economy, and produce many goods for export, but also import many goods.
For more information, see our Starport and Space Station Guide.
Most populated planets have access to one of the many Trade Routes known as Hyperlanes. Hyperlanes were routes through space in which a spaceship could safely travel without colliding with a body in space, or some other phenomenon such as a black hole. There were five major routes in the galaxy, with hundreds of secondary routes and thousands of minor ones. Scouting new hyperspace routes was an incredibly dangerous task for an explorer.
In many parts of the galaxy, hyperlanes required periodic re-entry into realspace to manually maneuver the ship towards the next hyper-point. Pirate raids were common in these spots. The Galactic Empire and other governments often sought to lessen this threat by constructing deep-space platforms and space stations located at hyper-points so ships could refuel, repair, or transfer goods. Mine fields and probe droids were also deployed.
Major Trade Routes
• Rimma Trade Route, established in 5500 BBY, was a major trade route that ran from Abregado-rae in the Core Worlds to Kathol sector in the Outer Rim.
• Perlemian Trade Route was a vital trade hyperroute that, along with the Corellian Run, made up the border of The Slice.
• Hydian Way was the only hyperlane that crossed the entire galaxy.
• The Corellian Run started at Coruscant, looped around the Deep Core, went through Corellia, and continued on to pass through Tatooine before terminating near the remote Outer Rim world of Naos III.
• The Corellian Trade Spine began at Corellia and headed in the direction of Duro. It eventually passed by the Greater Javin before tapering off.
Major Exports / Imports
This should be chosen by the gamemaster only after considering the government, tech level and planet function as a whole. The gamemaster must decide what the planet produces for its own consumption, what it ships to other planets and what it must purchase from other planets. The whole galactic economy is built upon the fact that most planets specialize in producing certain goods and must import goods from other planets for survival.
Imperial bureaucrats group goods within eight general categories. Within these categories, planets may export or import only a few products. The categories are: low, mid, or high technology, metals, minerals, luxury goods, foodstuffs and medicinal goods. For more information, see our Starport and Space Station Guide.
These are the names of locations of cities, towns, and villages. Capitals and cities with starports are usually identified here.
Points of Interest
These are locations that might be of interest to the player characters or may be mentioned in NPC conversations.
Where in the galaxy the planet is located. This may be the Core Worlds, Colonies, Mid Rim, Outer Rim, Hutt Space, or Unknown Regions
A sector was an area of space or land framed by an artificial, conventional boundary.
A planetary sector contained a number of solar systems. Sectors were also regional political divisions. The galaxy was divided into a little over 1,000 sectors. Under the rule of the Galactic Empire, individual sectors were placed under the authority of a Moff, or sector governor. Several sectors could be regrouped into an Oversector governed by a Grand Moff. During the Republic Regional Governors controlled the various political sectors and were in charge of protecting the hyperspace lanes and planets in their sector.
This the planetary leader if one holds this position. This can be an individual or appointed representative of the planet’s government. An example would be Queen Amidala of Naboo.
System / Star Name
Generally, the system and the star are named after the most important planet of the system.
The gamemaster should determine the type of star for the system. White, yellow-white, yellow, orange, and red stars could conceivably support habitable planets (yellow and orange are most likely). White dwarfs (which were once red giants) may have once supported habitable planets, but they were burned when the star became a red giant. Binary stars can support habitable planets, and although rare, this is not impossible, as Tatooine shows. This is possible if the stars are close enough to each other so that the planet orbits both stars, or the stars are so far apart that the planet can orbit around only one of the stars (this will almost always be the case). Trinary stars could also support habitable planets, but this is even less likely.
Distance from Core
This is the distance in light years from the Core Worlds.
The gamemaster, at his option, can elect to detail the rest of the system. This is a matter of choosing the types of planets and their names, and provided you don’t start explaining the detailed astrophysics of the system, odds are likely no one will complain.
In general, terrestrial planets will occupy the inner orbits of the system. Next will be the gas giants, possibly followed by frozen rock planets.
Gas giants will be the only planets capable of supporting habitable satellites. Most satellites for terrestrial planets will be little more than hunks of frozen rock and ice, although they could be a large “companion” satellite. Gamemasters can list other planets on the Planet Template. Moons of particular importance can be listed in the Orbital Bodies section).
As stated earlier, create the planets that fit your story. These are just guides to provide a hand to help gamemasters create worlds. You can always use a established world or create your own worlds for your stories. As a gamemaster you create the story and world that best serves your campaign. After you have a planet establish you can look into what kind of life and fauna will be located there.
