Crim had rented out Tzeentch's library for far too long. One fateful evening he checked out a book - bound in human leather, no less - whose title couldn't be pronounced by sane creatures. The librarian gave him some trouble but one twitch of his nostril told the beast he wasn't messing around, and soon the book was Crim's (although it was due by Wednesday of next week).

This was his first mistake, as he donned his true blue sweater and took a seat in the +2 armchair of leather. He cracked open the tome, glancing upon its unintelligible pages, and a spark of curiosity cast from his young, foolish mind ignited the carpet beneath his feet.

"Oh man, oh god, oh man oh god oh god oh man!" Crim the Dog announced, looking left, right, back, forth, up, and down for an extinguisher, but there were none to be had. Needless to say, Crim got out of there, book in hand.

Unfortunately, he took a wrong turn at the Astronomy section, where no man nor monster had set foot since Astronomy was invented. Crim knew if he didn't act fast, the walls of reality would close in and he would be lost forever in the halls of infinite knowledge. He took a gander at the novel in his possession, and decided on the wrong course of action.

Reading aloud the mystical runes contained within, a force overcame him. Blood spouted out of his mouth from the power of the foul words. He decided this may not have been such a good idea after all, and stopped reading. But he had already believed far too much. A portal to gods know where opened beneath his feet, and he began to fall into an endless spiral, his eyes bubbling out and demon spirits erupting from his hardcover and tormenting him for eternity.

(Fun fact: Crim's sweater was forever tainted by the warp.)
