Astarte is the only Goddess of Magic left, with the others either dead or stripped of their power. She is one of the Gods called forth in the beginning of time by Amul'Sharar and is the one responsible for adding a touch of wild magic into the Codex of Creation.
She is responsible for the creation of The Rock and thus, indirectly, the Beast, who now roams Galbar in search of souls to devour.
