Just when the Jewel Riders try to find the last Crown Jewel and complete the magic of Merlin’s Jewel Box, Lady Kale disguises herself as Queen Anya and sneaks into the Crystal Palace, where she seizes the Jewel Keep and with it the Jewel Box, as well all the magic jewels stored there. Using their powers to create a dangerous "antimagic" device, Kale time-freezes all of New Camelot. When the Jewel Riders find the final Jewel, Kale magically transports it into her hands and strips them of their powers. The girls are helpless to stop Kale from proclaiming herself the new Queen of Avalon.
