Mezmer Full Stop
RICHARDO! THE CRAZIEST PC NOW HAS THE POWER OF A DEMIGOD!
Pavor, the villain from the tutorial dungeon could qualify.
he's forcibly retired and kicked out of his own dig and sent to a sanitarium .Somehow though he gets out and sneaks into the dungeon where he found the book and six of his old students were still excavating. Pavor sets fire to everything, killing his whole crew, while he himself escapes deeper down. By the time the PCs track him down, he's naked, wielding two cleavers and has for some reason sewn his mouth shut and his eyes closed. The PCs kill him but no one knows why he did what he did. And no one ever found that book.
There's still that giant spider living at the bottom of the Superne Castle that no one talks about.

Brand harnessing peoples souls for that reason.
Whatever it is the Doffe's hands do.
The weepers in darkness.
The fucking Pox! It's the only thing that actually destroys your soul in this world!
The winds that we're carrying away Bobbie when her soul was separated from her body.
