The Order of Sir Martin (officially referred to as the Most Noble Order of the Fallen King), is a bloodline of the Nosferatu clan of vampires. Bloodline legend accredits the formation of the line to an ancient monster called Martin of Jerusalem in the late 11th century. In truth, the Order of Sir Martin acts as a sort of secret police for the Invictus, a rare few forsake the First Estate for the Ordo Dracul.
