I used to laugh every time someone told me the world was gonna end on December 21st, 2012. I used to make jokes about it, but that was before Sensei told me the truth. If I can't solve the four tasks before the twelfth chime of the Ninjago City Clock, everything I know, will vanish.

We used to be able to joke, but know we know, if we can't stop this, the world as we know it will vanish. There's a new evil rising, a new evil that threatened our very existence. All I know is, I have to go in alone. No one can help me.

Not Sensei.

Not Cole.

Not Jay.

Not Zane.

Not Nya.

Not Lloyd.

I'm on my own now, all I have is my sword and the clothes on my back. The invasion has begun. Already, his soldiers are terrorizing my people. My friends. Soon, he will have them all in the palm of his hand. That is, if I can't stop him in time. I may not know this place anymore, but I do know one thing.

My name is Kai, and I am the world's last hope.
