To those saying that the creatures aren't vampires: vampire is a generic term that refers to any creature that feeds through vampirism, i.e. on life energy/blood. Legends of such creatures have existed for millennia, through almost every civilisation, with each legend differing slightly, except regarding the vampiric feeding, obviously. The idea of the refined, charismatic vampire only really appeared with the short story 'The Vampyre' in 1819, before that there were creatures like the Romanian Strigoi, African Adze and ancient Babylonian Lilitu, all of which are vampires, just not the type popularised by novels like Dracula.
