To stop the MergeQuakes from getting worse, the Ninja travel to the Temple of the Dragon Cores to learn more about something called "The Coalescence."

Sora and Nya search for the Dragon Core with a magical compass. Arin and Lloyd get put to the test in Mother Garden. Wyldfyre and Kai play keep-away.

Bonzle and her team set out to search for a certain sorceress, but first they'll need a map. Meanwhile, Arin struggles with his Spinjitzu training.
