Bonetrader- The Koronus Expanse is strewn with the bones of alien races long forgotten. For most Rogue Traders, these ruins are curiosities at best and grim reminders of a shadowed time before the Emperor’s light spilled through the Koronus Passage and into the Expanse at worst. Most Cold Traders make their living sorting through the debris of forgotten species and passing on the baubles they uncover to the bored nobility of the Calixis Sector in exchange for vast sums of money. Of course, sometimes the alien devices and artefacts that Cold Traders salvage have greater purposes and powers than one might guess, and thus have unforeseen consequences upon their buyers. The dread Halo Artefacts are such cursed objects, and many of the lost races of the Koronus Expanse left behind equally wicked machines in the most innocuous of packages. While certain nobles will pay a great deal for any object of alien manufacture, there are those within the Imperium, and some say beyond, who do not wish to see the most dangerous of these artefacts entering the Calixis Sector. These cursed devices are the primary interest of so called Bonetraders, merchants, and grave-robbers who traffic specifically in psychically resonant objects left behind by careless or malicious precursors. For Bonetraders, psykers are an integral part of business. Only a psyker can be relied upon to separate valuable caches of buried artefacts from the detritus of dead empires scattered across the Koronus Expanse. However, as any successful trader knows, trust is a luxury, and a particularly expensive one at that when one is dealing with those touched by the Warp. A Bonetrader may need a psyker—or indeed, a great many psykers—to carry out his business, but he must also know how to handle the trouble that any given psyker could bring down upon him if he is not cautious. Beyond the usual perils of the Koronus Expanse, anyone who relies on taking psykers into potentially dangerous situations must be prepared to clean up the messes that follow.
