This is a small, struggling Colony which survives off the traffic from the core of the ICC out to the frontier world of Pandora. It is a domed Colony, as the atmosphere of Thedus is thin and has little oxygen. The world is not self-sufficient; it has a full space Service Base, but all other items are in short supply.Aliens Adventure Game (1991), Leading Edge Games.
There are three communities on Thedus, each of which is built around a reactor that also provides power for an Atmosphere Processor. The expansion of the Colony is limited by the shortage of power, and the population subsists on ship service and maintenance, and providing for the crews of vessels that are being worked on. The crime rate on Thedus is very high, and many unwary travellers never leave the planet.
