An ancient Mayan queen, Lucia (Shiva Negar) is accidentally summoned when a teacher digs up a crystal skull, and she prepares for a ritual that will unite her with a sun king and end the world. Rory, Ethan and Benny all fall victim to her spell, leaving only Erica and Sarah to save the day. By turning to Benny's grandma for information, they find out that Lucia is one of two sun gods who created Earth, but were split by the moon goddess's power. By using Ethan's moonstones, they manage to break Lucia's hold on their friends and destroy the skull, and the queen altogether. (thetvdb.com)
