Cain Nightrode is the pretty much the Leader of the Rosenkreuz!!

The vampires terrorist organization Rosenkreuz and its members are the primary antagonists in the Trinity Blood series. The Orden is led by the crusnik Cain, who is also referred to as "Contra Mundi."Preferring to work in the background and keeping their activities secret, they often manipulate unsuspecting humans and vampires into doing their dirty work for them.
The Orden claims to want to make a "new world order," and many of their activities center on triggering a new apocalyptic war between the Vatican, the New Human Empire, and Albion. Given Cain's desire to destroy the world, however, he may be manipulating the entire organization to suit his own own personal vendetta.
