I''ve been discussing with a friend about an idea for a DH campaign and was wondering how it holds up.
A group of acolytes are hunting a dangerous heretic on a derelict ship / in an underhive / insert any dark spooky place with their inquisitor. The men and women have served together for a long time and the inquisitor is a charismatic, bold individual. The kind of guy you''d follow to Hell and back. The group corner the heretic, only to be ambushed themselves. The villain offers the inquisitor power and glory for a price, to which the inquisitor surprisingly agrees. The acolytes are deemed as a sacrifice and have to escape an overwhelming onslaught of warp entities and madmen.
The acolytes, shocked by the inquisitors betrayal, manage to escape the situation and are captured and questioned by an another inquisitor, as well as suspected of heresy. However, they are given a chance to redeem themselves and clear their charges. All they need to do is to finish their mission, as well as to hunt down the traitor inquisitor.
