Together with her two siblings, she was a progenitor of the contemporary Hive species and one of its chief gods, having made a pact with the Worms of Fundament. She is driven to become the mightiest warrior in the universe. After the Hive's conquest of the Harmony, Xivu Arath and her Hive left her siblings for deep space, claiming Oryx had grown too powerful for her to accept. Her current whereabouts are unknown.
