Azim

Azim was one of the older vampires. He ruled as a god for a thousand years in a secret temple in the Himalayas, where those who went to worship him never returned alive.

He conducted disturbing rituals and entices Pandora to participate in them in return for Marius' location (when Marius gets trapped in the ice after Akasha awakens).

Akasha spares him during her worldwide slaughter, but for a purpose. She sees him as the ultimate symbol of vampire evil and explodes his body in front of human witnesses.
