The Librarian

This ghastly figure collecting knowledge and souls. No one really knows what his true purpose is. Letters that bring unsuspecting adventurers the his lair with unknown magic are part of the tales that mother tell their children when they misbehave.

The Librarian is the ruler of the Great Library and commands the Candle Golem and the Ink Fox. His most loyal and vile subject, however, is the Demon Wall.
