I've got an idea for a campaign and could do with some input.
The basic premise is that the PCs start at rank 4. They've been reliable acolytes for a while now doing various acolyte-y things (and i might ask them to write me a short list of their notable exploits as background). However, their inquisitor has recently died (warp accident). How sad. An trio of other inquisitors have asked the dead inquisitors interrogator to tidy up his affairs, gather his assets and generally wrap things up.
This interrogator has gone through the dead guys files and merged all his acolytes into several cells. The PCs are one such cell. He is now going to use them to help him tidy up the dead inqusiitors affairs and after that as a mercenary/black ops group to achieve things that need to be done "off the books".
Early missions will focus on silencing former acolytes and agents who know too much and are judged (by the interrogator) as untrustworthy. Later he will start using them to achieve inquisition missions, particularly where they can't go in wavering a writ of authority.
Eventually, he'll see the profit motive and start renting them out to all and sundry including rogue traders, criminals, other branches of the adeptus, etc.
The PCs will often be in the dark about the aims and orientations of the jobs principal. They will receive dossiers of information about their job, a slush fund type budget and told to get on with it. If they are captured they have suicide catechisms that can be used to self terminate.
First mission will be killing a trio of people on Prol VIII, former acolytes/spies/etc.
Second mission will be recovery of some of the dead inquisitors effects and murder of those investigating them (on a train between hive cities, yay for train heists!)
But i'd love some more ideas of missions for them to do.
Ideally i'm after quite simple missions, not long stories or continuing sagas. And they are being used mostly as an off-the-books black ops team, a bit more militant and a bit less investigate-y than most DH teams. These are the guys you send in to get stuff done, not the guys you send in to figure out what needs to be done. Earlier missions will be tailored to cleaning up an inquisitors business, then general inqusiitorial tasks and finally all kinds of stuff.
Any ideas?
