Chapter 1 : darkness rises

After the destruction caused by lord garmadon the ninja and every citizen of ninjago was helping to rebuild ninjago city .

Sensei Wu told kai ' I left some boxes at the temple of airjitzu , go pick them up for me .

Kai groaned but as he was told .

Kai's pov

I was merely heading towards the airjitzu temple when a dark shadow of sorts crossed paths with me and before I knew it , it went right through or rather in me . Now I know how Lloyd felt when he was possessed by morro .

One month earlier :

The colosouses was marching through the city destroying everything in its path , the remaining ninja as well the resistance were fighting back with everything they had left . Even so it wasn't enough . Ronin smirked and said ' if I had a quarter every time the city was attacked i'd be rich ' . As always the unexpected seemed to happen , a portal had opened up in the sky revealing Wu on a dragon wearing the golden armor followed by kai , jay , zane and cole each on their respective dragons . Everyone was overjoyed with seeing their friends again that they failed to notice that they weren't the only ones to escape through the portal . A dark shadow or if you look closely an oni also escaped .
