In the oldest tales he has no name, and is simply called "the Traitor", but was presented with the name "Ahab" during the Dark Ages. Others claim that the traitor's name was wiped from the clan's history, and he was given the name "Ahab" to mark his treachery in the wake of the Baali Wars - so it isn't clear if he is a 'Judas figure' or an actual vampire.
It is said that Ahab survived the Baali Wars by betraying his battle-brothers to devil worshipers in the dark caverns. According to Salubri lore, he continued dealing with infernalism, and some even imply that Saulot's diablerie was only possible through Ahab's intervention.
