The Blood Moon

Skender Albescu is a man with a curse, sinking him down into the depths of insanity. Vampirism grants him superhuman abilities, but costs consumption of warm human blood. Without it, a neverending existence of burning pain and mindless rage awaits. His only cure is to undo the unholy bargain and slay the demon, Khaban, that bestowed it unto him. The magic of the moon is slow to forgive a murder, though.
