Trevor is the last of the Belmonts, a family dedicated to monster hunting, so as to protect the citizens of Wallachia. The Belmonts fell on hard times when the Church excommunicated the family and banished them from their ancestral lands. Given practices of the Church's leadership, the excommunication was likely done because the Belmonts knowledge conflicted with the Church's teachings, the association between the Belmonts and the monsters they hunt, the Belmont's martial power.
