Hello once again! I've been asleep for about a year now, but I'm back. Two years ago I played a 3-session Dark Heresy mini-Campaign with some childhood buds, but all the missions and characters were taken from online.
This time around, I'll be using the 2ed book and mostly making up the plot myself. I would like to give a brief summary of my thoughts so far, and then ask for any advice a Dark Heresy
GM might give me on things I should read, things to consider, etc. Some expert advice!
For an acolyte to be raised to the rank of Inquisitor, the consent of three Inquisitors or an Inquisitor
Lord is required. There have been cases where the situation has called for an acolyte to take on full
Inquisitorial responsibilities immediately without the blessing of three Inquisitors or a Lord. For
example, if an acolyte's Inquisitor is killed in action, he or she may inherit their Inquisitorial Seal
and fulfil the role of an Inquisitor subject to repeal by another Inquisitor.

I thought I'd play around this, having the acolytes arrive in the Askellon system from 2ed to meet an Ordo Melleus Inquisitor who is a nice guy, and then dies tragically. The system is described as having very few inquisitors, so I think i'd have them take up his role and finish solving whatever crises ended their beloved leaders life.
Following this, I was thinking another Inquisitor would arrive and repeal the Inquisitorial Seal, and he'd be a mean old dude sending them on gak missions. Eventually it would be learned that he is a shapeshifting Daemon and was playing them for fools! Damn him! Revenge would be enacted, everyone is promoted by an Inquisitor lord to the rank of Inquisitor, and as a sequel they could form a conclave to kill the demon when he comes back from the warp.

NO ONE EXPECTS THE INQUISITION
