Hecate is a Titan who sided with the Olympians in the First Titanomachy. She became known as the Goddess of Magic as a reward for this alliance. However, she has been bitter toward the Olympians since the end of the war because she was not named a major Olympian Goddess. Instead, she has spent the last five thousand years covertly working with Kronos to free him and overthrow Olympus. Particularly, she holds a grudge against Hades for holding a vast and powerful realm that entitles him to be called a major god despite lacking a seat on the council. This hatred is furthered at the end of Lightning Thieves when he returns to the Olympian Council.
She is one of the maiden goddesses, and as such, most of her followers are instead the natural sorceresses whom she patrons.
