Sarahlia is a human warlord.
Despite riding around on a giant bat, having a spirit bat following her around, creepily collecting vials of blood from fallen enemies, and having eyes that flash red in the presence of blood, she firmly maintains that she's not a vampire, what are you, crazy?
She was last seen pissing off Orcus, while in a temple of Orcus, and desecrating a symbol of Orcus. Orcus closed the portal, trapping her in his realm. After several weeks of torture, Orcus finally killed her. Her body was dismembered and sewn into ten different ghouls, which ultimately wound up under the control of Harthur as exarch of the Nightbringer.
