Ha, I knew that someone from Hosa would try to kill him, especially some kind of maniac who burns everyone who comes) poor Lynch, it's dangerous to visit madmen
apparently, he was an Inquisitor or an Abbot :(
He couldn't have been an Inquisitor, as far as I understand.
Maybe Brack cursed or poisoned him, and he started eating coal for some reason. Or maybe it was a helpful tip from a healer.
