The Inquisition

Inquisitor Schongard stepped back from the table where Glaw was strapped and pulled off his soiled surgical gloves.  He was a broad man with thin brown hair and a chilling mask of black metal surgically fixed to his face.  No one knew if this mask covered some grievous injury or was simply an affectation.  Dark, unhealthy, bloodshot eyes regarded Endor and myself through the oblong slits in the metal.
"Brothers," he whispered.  His phlegmy voice never wavered from that low, hushed level.  "His resistance is quite the doughtiest I have seen..."
--Dan Abnett's Xenos, Book One of the Eisenhorn Trilogy

Everybody wants to be an Inquisitor.  We want the power to move among worlds, to have generals and emperors do whatever we say, to command fear and devotion in the average man.  We can't help it.  That's one of the main reasons why Warhammer 40,000 is as big as it is.
Oh, and Eisenhorn is a wuss and he should use his Inquisitorial postition to its full extent instead of pansying around with local laws and working undercover, but that's just me.  At least he's not a liberal.  Then nobody would buy the second book to his trilogy...
Anyway, Inquisitors rule.  Always have, always will.  These are the men who are fiercely loyal to the Emperor, or at least to their ideas of him.  They move through the Empire and beyond like avenging angels, striking down enemies both real and imagined in the name of the Emperor Deified.  Raging Chaos daemons and the twisted alien gods fall before them like wheat before a scythe.  They are the Imperium.
The Inquisitor roleplaying game is probably awesome to play, if they would have just set it up properly.  They should just use the existing 40K scale of figures, so you'd have an unlimited source of stuff to fight, and you could use your existing armies in the games.  But hey, what do I know?
Inquisitors have always been able to be added to Imperial armies, but now those awesome heroes among men at GW have made an army dedicated entirely to the Inquisition.  May the name of Andy Chambers be praised, yea, and the name of Gavin Thorpe be exalted.  May the cherubs and seraphs sing praises to the GW staff, and may their offspring be plentiful and their lines never fade...
Right, where was I?  Oh, raving about the awesome Inquisition.  Actually, there's probably no need for me to say any more.  The inherent coolness of the Inquisition should speak for itself.  If you don't agree with me, you can expect a visit from your local agent soon...
