A world of fear and darkness, where after becoming an even darker creature of the night in order to defeat Dracula, Batman succumbed to his curse and spread the vampire plague to the rest of Earths heroes, forming the Blood League. These unstoppable super-vampires have chased the quenching of their thirst across the universe, waging war against Rann and its defender Adam Strange. However, an attempted invasion attempt of Earth 13 resulted in their appetite for blood being redirected by the sorceress Annataz towards coffee.
