Mainstreaming refers to a social movement within the vampire race, in which vampires attempt to integrate themselves into everyday human society. The mainstreaming movement was made possible by the invention of synthetic blood, which prompted vampires to reveal their existence to humanity, in an event known as The Great Revelation. The Great Revelation was informally known as "coming out of the coffin," and was orchestrated by Roman, the Guardian of the Vampire Authority. Attitudes towards mainstreaming within the vampire community were mixed, with some, particularly older vampires, regarding "mainstreamers" as traitors, who have lost all sense of their priorities.
