System Details

Upsilon Andromedae is a major population center of the Bandorian Protectorate; at just under 45 light-years from Sol, it is within easy return-trip range of most warp-capable ships, and the warp spacelanes are less dangerous and more documented closer to Sol. This system has four planets; two of these are technically in the system's habitable zone, and one of them has two terraformed, inhabited moons. The fourth planet also has one large moon, but it has not yet been terraformed to make it completely habitable for humans. The two terraformed moons both had some indigenous life, and the terraforming process was completed with minimal extinction of existing species. This system is renowned for its rogue asteroids, and both the inhabited moons have many shield satellites that are placed in position to take the full impact as asteroids enter the moons’ upper atmospheres; these satellites are equipped with thrusters that allow them to push the asteroids to escape velocity away from the moon. Unfortunately, the massive gravity of Obariant pulls in many rogue asteroids; however, they do not usually hit the moons. There are several space stations orbiting Obariant which are equipped with powerful energy weapons and missiles to destroy incoming asteroids; these are usually effective, but the shield satellites are there just in case. The last asteroid impact on the surface of Degaulle occurred in 3269, and the last asteroid impact on the surface of Gnatabon occurred in 3321. Many Bandorian naval ships are based in this system, and the Duskhan League has a major presence here as well. This means that there are many Kroll ships in the system, and this makes some people nervous.
