Stirba is a ten-thousand-year-old sorceress and the queen of all werewolves.

Stirba maintained her werewolf coven inside of a castle keep in the mountains of Transylvania. Here, she conducted various occult rituals which involved blood sacrifices and orgies.

Stirba's greatest nemesis was the werewolf hunter Stefan Crosscoe, whom she referred to as her "brother" and her "beloved".
