Talya

Talya was the consort of Razza before Riftwatch fell. Their relationship was fraught: Razza was cheating on her, and ultimately betrayed her for the succubus Xeriope; Talya seemed to be having her own secret relationship with Adorenna, who was Razza's apprentice at the time. They were using some kind of arcane device for their purposes that required the sacrifice of sentient beings. Ultimately, after perceiving some failure on Talya's part, Razza used the device on her, presumably killing her. The device was operated by Adorenna, who was deeply shaken by the experience.
