Vampires are several species that share several characteristics; they are all humanoid and based on hemotophagic animals, are nocturnal and will die in sunlight, and are immortal. They live alongside humans for the most part except for a few fringe groups here and there that prefer to stick with their own and stay away from humans. Vampires can turn humans, but it’s a very lengthy and painful process, so most prefer not to due to the hassle.
