Seshru

Sassy Sexy Seductive Sussy Silly Ssssssssy Seshru (this is just cringe lol), or simply just Seshru, all we know is that she changed her name at some point, is Renn's mother, and also the exiled Viper Mage: one of the Soul-Eaaters, Yeah, she's hot, but don't look into her eyes, she could hypnotize you into doing whatever she wants. She also has a few big snakes, and clutches a piece of the fire opal, before this bit was destroyed.
In Outcast, Seshru did not plan to kill Torak, just take advantage of his spirit walking ability for presumably malicious purposes. Combined with her seduction power, Seshru could go far. Seshru also wishes she could have made Renn into a tokoroth. Her signature sign was a stick with a clay blob for a head and some googly eyes, which she used to drive Torak into insanity with. Just imagine the dumbest object you've ever seen having such a capability. Then Seshru broke the glaciers and began to flood Lake Axehead, before several clans came along to mob together, the most epic ending in any of the COAD series, Renn smashed the piece of the fire opal, which Seshru wielded, Seshru got arrowed once before shrinking into wtf pain from watching the fragment be destroyed.
