Sabel Jackson was taken from her mother, Sally Jackson, and twin brother, Percy Jackson, at the age of one. Although she was raised by Chaos, she refuses to take any power from him as he took her from her real family. She was just like her brother turned out to be-sarcastic, strong, all ways getting in trouble, and loyal-and obeyed almost all of Chaos' wishes. She watched over Percy ever since they were both five years old and always found a way to help him out, even though it was against Chaos' wishes. After Bianca di Angelo dies on a quest in the place of Percy, Sabel wanted to show her gratitude and revived her, allowing Bianca to be able to look over her brother, Nico. Bianca and Sabel grow into the best of friends and Sabel trains Bianca to defend herself.
Sabel gets into an argument with Chaos about not being allowed to go see her brother, which turned into a fight shortly after. Chaos and Sabel fight full on, powers and everything, and when Sabel ends up winning, her and Bianca go down to Earth to see their brothers. Sabel finally gets to meet her mother and her brother and Bianca finally gets reunited with her brother. But the real question: do Bianca and Sabel get to stay on Earth?
