Medieval Europe: Father Christmas is a fading memory, after Christmas hasn't come for several years. A young orphan girl, Ayden, receives a magic crystal from a dying elf, with a warning that the North has lost its magic, and that she alone can save Christmas. Ayden and her orphan friends begin a perilous journey and must escape dragons, goblins, bandits, ogres, and other fantasy creatures as they team up with Airk, the wayward son of Father Christmas, to return a stolen Christmas orb to the North.
