Troile is an ancient Cainite, and the progenitor of the modern incarnation of the Brujah clan. According to myth, the original Brujah Antediluvian was diablerized by Troile, who was his own progeny. It should be noted that, while Troile is not technically an Antediluvian per se - at least, not by Embrace - Troile is frequently referred to in this fashion after becoming a third generation vampire.
