a guy in some village, who was a complete kook and seemed to think he was a goblin. The guy never dropped the act, even when i mindread him, but i later found out, that the village was terrorized by a demon who required human sacrifices. I wonder if the guy started his act to get away from being offered to the demon, but "lived too deep into" his character.
Edit, another good example was a nasty prankster wizard, who soulforged a guy with a chicken (soulforge in DivDiv2 lore means, that if either one of them is hurt, the other dies too), and also has several encounters with the pc, where he speaks in rhymes and summons monsters, that attack the pc.
Another example is a quest, where a talking tree wants you to get rid of a goblin, who has pissed it off by literally pissing on it
