Korowin, the Mad

Korowin, the Mad is a patron associated with forbidden knowledge that comes at a cost. He found his origin when he stole a book from Palarian's library that has given him nearly limitless knowledge. He will offer his knowledge to you in a seeminly gracious display of goodwill. This is merely an act, the more and greater knowledge that someone draws from this patron, the more they lose their minds. Even after accepting forbidden knowledge once, some report a strong internal urge to read more, even when they're aware of the effect.

"More. I need to know. Any price is one worth paying. I can find a way out of this if I just go deeper."
