As an Inquisitor you have for a time pondered on the sudden collapse of warp routes to an strategically vital fortress world and junction of warp routes but none of your investigations into the area has given any result, nor has attempts to contact the planet been successful for Astropaths. The world is specially important because with the warp routes to and from it down an entire sub-sector is cut off from the rest of the Imperium, just now when an Ork Waaagh is anticipated to be launched upon it its separatist plagued worlds.
But suddenly time seems to stop and an inhuman voice whispers to you, telling you of the tech-sorceries employed by a previously unheard of xenos race to break communications to and from the planet, and that the population have been overrun and enslaved by the aliens. The voice offers to produce an agent of extraordinary capabilities to re-open the warp routes, but in exchange for this service the voice requests thatyou shall agree to give up any single one thing that is yours to give in the future when the voice so decides to collect its debt, or it promises to see to your continued existance in misery and defeat.
What to do?
