Haven: Abandoned Orbital Uplift Base

From publisher blurb: Shaped like a long, thin, empty tube, 33/94/09.55 is a damaged and abandoned void factory which once produced advanced circuitry for laser weapons has now been taken over by a large group of mixed Uplifts, eager to escape persecution on some of the Flame Worlds. The orbital has been renamed ‘Haven’ and has since become hostile to humanity and a magnet for renegade Uplifts.
