Moderately tall, greying at the temples, and charming - when he isn't talking about the Ancients
Hamilton Alexander is the leader of a “coven” or group of the Cult of the Ancients. In conversation, he alternates between an intense, charismatic charm and the sense of near-lunacy as he details his beliefs and the goals of his group.
Met by the party first in The Brotherhood of Knives during their adventure “A Knife in the Hand is Worth Two in the Back”, he has hired the group to protect the sect members on their trip to Athame (The capitol world of the Brotherhood). During the trip, he and his followers had several meals with Xavier and invited Hat and others, though for the most part they declined invitations to dine.
The party suspects Hamilton (or his followers) of being secret powerful psionicists, mind-controlling their audiences during their public discussions of their religion.
