To her horror, she learns that her mother serves Wrath-Amon and her father is the serpent man Astivus, making her a half-breed. From that moment, she is terrified her Serpent-Man heritage will assert itself. When her father Astivus, who loved Jezmine's mother, sides with Jezmine and her mother against Wrath-Amon, Wrath-Amon banishes her father and mother to the Abyss. A magical potion applied to her Star Metal shuriken allow Jezmine to magically summon the throwing stars to return to her. She shared this potion with Zula.
Jezmine hated Astivus, despite his love for her. She and Conan were able to free her mother during a trip to the Abyss, and later Astivus escaped when Set and the Serpent-Men banished over the years were freed from the Abyss by Wrath-Amon. Once again, Astivus chose Jezmine and her mother over serving Set, and it is implied in the final episode that Jezmine might be willing to reconcile with him. Unlike Valeria, Wrath-Amon doesn't kill her.
