Xanthor

Xanthor's portrait from Might and Magic VIII: Day of the Destroyer.

Court sage and advisor to Catherine.

Horn of the Abyss 

He was captured and imprisoned by the barbarians and eventually rescued by Bidley. In gratitude for being saved, he told Bidley the location of Island of the Vengeful Serpent - the resting place of the Horn of the Abyss. But the truth was, he hoped that the pirate would die. Bidley (and maybe others) believed him to be a  Mage.

Later, after finally getting the Horn of the Abyss, Bidley was asked to give it to Gavin Magnus by Solmyr. He quickly suspected Xanthor of telling the Wizards about the Horn.

Lost Lore 

Xanthor (along with Marcus Finch) is a professor at the University of Erathia and the narrator of a few legendary accounts of events around Antagarich during the events of Heroes of Might and Magic III. According to these stories, he is the nephew of Agar and has 'little training in the mystical arts'.
