Hermit: an always-generated-peaceful, sessile human monster. Possibly only one can generate per game. He or she collects books and will ask for books when chatted to. In exchange for each book, they dispense a rumor which is false if the book was cursed and true otherwise.

A more complicated extension is that rather than simply taking the books, they could instead stash them into a magic-chest-like extradimensional space, the contents of which show up in an identical chest in the Wizard’s Tower. The significance of this is left up to the player’s interpretation.
