Zura is the Goddess and Queen of vampires. Orcus sees vampires as something created by plague or disease. Orcus prefers liches and undead that are created by necromancy. However, Orcus doesn’t realize that Vampires can be created from necromancy as well.
Zura is the mate of Bane. She wants to be the goddess of the undead and Bane wants to be the god of the living. Together they work closely together. For she knows without the living the undead can’t exist. There has to be a harmony of balance to keep things in order. Lawfulness is the only this can work.
Zura is the first Vampire and made a Demon Lord by a more powerful Demon Lord.
