Royal Librarian of Liathonia
Zathan is the Royal Librarian of Liathonia. He manages an immense collection of mundane and arcane texts in the library in the Liathonian palace, which is at the heart of Vegolis.
He was nearly executed by Rodger Liathon on false charges. The heroes saved him, and he saved the heroes by teleporting them out of the fight, which they probably could not have won.
