I think we can all agree, Warhammer 40k's Inquisitors are cool customers. Once you put aside their whole shtick of being able to commit genocide on a whim, exterminatus-ing planets that have fallen to the predations of Chaos, they're basically Witch Hunters hanging out in a moody and noir-ish sci-fi future. There's a reason folks are excited for Dark Heresy.
They get to wear fun hats, run around with inquisitorial warbands filled with strange characters and xenos, and they get cool names like Ravenor, Eisenhorn, Adrastia, and Obiwan Sherlock Clousseau. Wait, what was that last one? Oh, you aren't familiar with the work of Obiwan Sherlock Clousseau.
