Clearly not a hemovore by birth, Lawrence is intent on receiving the synthesized hemovore serum that Virgil's brother Trey unwittingly created.

Mother Taneesha and the Hell's Belles - Cross-dressing pimp (and hemovore) Mother Taneesha runs a seedy nightclub in New Orleans' "Storyville" district.

Virgil learns that Trey had unwittingly taken part in a plan to synthesize the hemovore mutation, creating a serum that Wolfinger intends to sell on the black market to anyone wealthy enough to procure its fountain-of-youth-like properties.

They were created when the Ancient Haemovore went back in time to follow the flask containing Fenric's life essence.

Fenric begins to give orders to the Ancient One, an old Haemovore in control of the other monsters, to continue to assault anyone in their path.

He hadn't told her what was happening, because of her own part in it all. She was one of the wolves of Fenric, doomed to die, to rise as a haemovore, to seek the flask and free Fenric.
