Two powerful brothers, separated at birth, find each other after being tortured and turned into vampire killing machines by sinister forces for use as weapons of Dark Ages warfare. They were fierce when starved and then unleashed into battle and slaughtered an astonishing many. But while being immortal, they were not immune to manipulation, lies, betrayal, or their own growing desires for truth and morality in a brutal world. Upon further transformation into creatures even more powerful than all the vampire elders, they struggle in their quest to maintain peaceful lives across history, from Medieval times to Nazi Berlin and present day USA, searching for answers to existence. Neither one wanted to be monsters, but was there a way to use their powers for good?
