Every hundred years, the Circle of Gaea appears in a different location. In 2002, it was located in Golden Gate Park. The Charmed Ones, Leo Wyatt, Darryl Morris and the Elementals, Tyler Michaels, Rafe, Gabrielle Chambers, and Muriel Hammond found their way to the Circle where they confronted the demon Tempest. With much effort, they defeat the demon and successfully perform the ritual to save the world.
