Vipero hopes to alter the ancient prophecy. He orders the Dragons of the Dark Rift to find and eliminate the Sol Dragones. If they succeed, nothing will stop him from destroying Diego's world and claiming ownership of Sol, a star with unlimited spiritual power.
Diego and Racquel travel with their dragons to the Dark Rift, the entrance to the magical realm known as the Xibalba. Together with the Sol Dragones, they battle Vipero's immense army in a fight to save or shift the Mayan prediction. The fate of earth depends on victory or defeat, and Diego is the key.
His choice - to betray Magnifico or stay true to the Sol Dragones - will determine the outcome of the conflict.
