[@Tenlock] Oh you are free to play a sanctioned psyker in a regiment, but as far as being anything to do with the Inquisition...that is a no-no. This is, as the title suggests, a Guard RP. We have no time for the Inquisition here.

I would have thought a regiment cobbled together to form a spearhead would have been a top priority for the Ordo Militarum. Watchful agents to make sure guard who have already lost the bulk of their regiment don't get any independent ideas.

But, if you are really against the idea, I'll just run with the Commissar character, well, commissar acolyte.
