Rogue Trader 2015: Halcyon Rising
Considered accursed by many, the Xenosium is a dwelling place intended for the alien. Great upheaval attended the construction of the Xenosium, built at the order of Parsimus Dewain near the end of his life. It is made in the fashion of a prison-fortress — thick-walled and psy-warded. Void-weathered statues with stern faces look inwards at each corner. Often it is said that no human has set foot inside for centuries, but on several occasions, Rogue Traders have brought xenos representatives to Footfall — sentient alien beings, not the beast-traffic intended for circuses and xenosepts — and housed them within the Xenosium. No one seems certain whether or not the Xenosium is presently empty.
