Aduba-3 was an isolated planet on the Outer Rim that became a haven for criminals and spacers with nowhere else to go. Originally settled by colonists from the Sacred Way religion, Aduba-3 became saturated by outsiders after a bogus chromium rush—this scam, run by the criminal Tenloss Syndicate, led to the planet's sole city of Tun Aduban becoming a shadowport by the era of the Galactic Civil War.
