Hecate

Treasure tools:
- Trigon - which she seen frequently with
- Traverso - her personal transverse flute which she sometimes plays.

One of the Trinity of Bal Masqué, entitled as "The Priestess." Members of Bal Masqué refer to her as "Our Great Priestess" and Margery Daw refers to her as "Princess of Stars." Sydonay cares for her a lot, and to her dismay, Sydonay often calls her "My Hecate." Bel Peol always mentions turning her into an "eternal existence." During the creation of the Great Binding Chain in ancient times, she went by the name "Nüwa."

Hecate is a sad, quiet, and somewhat emotionless character, who has taken up the habit of prayer, despite having no one to pray to and Bel Peol considering it an odd thing to do, and frequently laments that she is "empty."
In the light novels, it is implied that Hecate is praying to Bal Masqué's god, Snake of the Festival. Hecate's emptiness is a result of her lack of sense of self.

Her position is very important with respect to what the Bal Masqué plans to do with the Reiji Maigo, since she is the one who can take the power of Reiji Maigo and send it out to everything in Seireiden.

In contrast to her counterpart in the anime, the light novels depict Hecate as a cold and feared leader that even the entirety of Bal Masqué fears her. She has a hobby of trekking up mountain tops, yet she despises mountain climbers who litter her favorite sites, so she slaughters them on sight.
