Ninjago: The Dragon's Crystal

A long time ago, before elemental masters existed, elemental dragons were in their place. These dragons had amazing powers, some could cook meat by breathing fire to create delicious meals while others could sooth wounds by creating some cold ice to cool them down. These dragons used their powers for day to day life until the humans came to their island. At first they where treated like friends until they turned on the dragons. Using their powers, they tried their best to fight off the humans, many dragons being slaughtered in the process. But then the First Spinjitzu Master arrived, and turned one of each element into a human, elemental masters to be exact. These elemental masters were humans, but they could control the element they where given. In order to protect them, The Queen Of All Dragons and The First Spinjitzu Master created three elements. The protectors. These where energy, void and fear, but energy banished void and fear to be in the spotlight. Left behind from these events are the Dragon's Crystal, the Red Crystal and a mysterious crystal. The Dragon's Crystal can turn a human into a dragon, which is a painful process, and the Red Crystal did the opposite. The day has arrived for the dragons to get their revenge for what the First Spinjitzu Master has done, and to return the elemental masters back to their original forms, and in the process, finding the answer to a mystery. Where are the masters of void and fear?
