Castellan Crowe
Castellan Garran Crowe is the simultaneously both the Captain and the Brotherhood champion of the Grey Knight Purifiers. Ironically, aside from the standard Matt Ward dickery, the Crowe is probably one of the only Grey Knights (other than Brother-Captain Stern. FUCK YEAH) that has not earned the rage of the Knight players.
Why is he is not part of Ward's Dick Club?
It is partially because of this fucking weird sword. A daemon sword (WTF!?) called the Blade of Antwyr. Crowe acquired guardianship of the sword because it had mindfucked and ass raped every other guy who used the sword but has not affected him. This surprisingly pleased many Writefags who have grown weary of the fuck overused evil-thing-corrupting-good-thing cliche of many occult genres. The fluff is fairly straightforward and states that Crowe is constantly brings him physical and spiritual peril as the sword attracts chaos to it wherever he goes cough...One-Ring...cough, constantly trying to corrupt him in the process.
Though most veterans have rightly begrudged Crowe's retarded Ward stats of fuckwittery, many believe that during the time Ward was writing the Grey Knights Codex, he had walked out of the room to glance at other shit-pieces of his work in an effort piss off more people with his faggotry. So distracted by his own self-proclaimed awesomeness, that a more competent writer (i.e. everyone) had happen to see one of the hero characters he was working on and sat down to write the rest of this hero's backstory. Matt Ward being the Spiritual Liege that he is, did not notice that one of his heroes had become awesome and simply moved on to the next idiocy he was planning to do. Thus were we given this little chunk of reprieve in a book filled with Rage.
