Seven years ago, the Empire came to Ninjago to take it over as their expansion of the galaxy grew. While the ninja fought them, an explosion happened that pulled Ninjago and the sixteen realms parrel to it together in an event we now call the Merge. The ninja disappeared after it, and the Empire easily took over the merged lands. Arin and Sora have been best friends since the Merge and Arin hopes his childhood heroes return so that he can find his parents. One day during a race, a dragon comes out of nowhere being chased by Dragon Hunters. Sora and Arin try to save the dragon, but get captured along with it by Lord Ras. But the two get saved by none other than Lloyd Garmadon, the former leader of the ninja.
