Juliette was once known as Nerthus, who was described by Tacitus in his "Germania." After a millennium on the run, however, she came into contact with St. Hildegard of Bingen in the 12th century, who provided her with an elixir that ended her dependence on human blood for sustenance. Since then, Nerthus (now known by her alias, Juliette de Montrose) has been a philanthropist, aiding penitent vampires who want to escape from the path of evil and become useful to the humans they once preyed upon.
