Dracula was a novel by Bram Stoker, named after the eponymous villain, (COMIC: Bat Attack!) who was based on Vlad III. In his life, Vlad had actually campaigned feverishly against the vampiric Mal'akh, and in the City of the Saved he hated the reputation that the book gave him.
Bram Stoker was friends with Richard Francis Burton, who was an expert on vampire legends and the Mal'akh who inspired them; Burton's research may have contributed to the novel. (PROSE: The Book of the War)
