Trevor was the last surviving member of the Belmont clan, a family who dedicated their lives to fight creatures of darkness commanded by Lord Dracula and protect mankind. However, rumors spread that the Belmont clan practiced black magic attracting evil to them, causing the family to be exiled and excommunicated by the Church, with everything the family owned being razed and destroyed by the people they swore to protect, eventually leaving Trevor all on his own at an early age.
