The Color of Blood: Primordial Vampire

After death, Caleb thought he was destined to wander an empty purgatory for the rest of his existence. When a chance encounter with a dead goddess of death offers him the chance to leave this place, he only reluctantly jumps at the opportunity. It's only after he spawns into a brand new world that he realizes that she actually never offered to bring him back to life. There, he finds he has become the Primordial Vampire. And some of the locals deities aren't happy about it, especially when he begins to gather followers for his dead goddess.
