She explains to Daniel that Anubis has unleashed a race called the Haaken who had been imprisoned by the Ancients thousands of years ago after they used Ancient technology to relentlessly attack the Ancients, Asgard, Nox and Furlings. She tells SG-1 that there are three pieces of the artefact and that it was originally created by the Ancients to bind the Haaken away, and that Anubis seeks it in order to control the Haaken.
