Once Upon a Time, a group of spell punks created a mask for a great king, referred to as the Nightmare King. The Nightmare King used the power of the mask to terrorise Skylands, before eventually the mask was stolen from him and split into 8 pieces all across Skylands. Thousands of years later, Kaos has set out to find all the mask pieces to reunite them and destroy Eon and the Skylanders, prompting them to try to find the pieces before he can.
