Gilles de Rais
Vlad Tepes, Elizabeth Bathory, and Gilles de Rais, three of the twelve master vampires, form an alliance and enter the mountainous area of Helea, killing every person they find. They then attempt to awaken Lilith, the mother of all vampires, so that they can have her power. Opening her tomb does not awaken her, but it does create a cloud over Helea that blocks the sun, making Helea a dark eden for vampires.
