31 parts Complete (Takes place after Hands of Time and before Sons of Garmadon). Since Kai and Nya found out what happened to their parents, they feel whole. As for Cole, well, after all those incidents, for some reason, now he feels even MORE separated from the team and doesn't know why.
Ever since Cole went through the rift of the Yin blade back in Day of the Departed, he thinks everything with him is back to normal. But just in, Ninjago City is in great danger and the ninja now have to face a new enemy.
That enemy wants Cole himself.

And during the adventure with Kai and Nya (HoT), Cole discovered a new power inside of him. It was powerful. He liked it, it helped the ninja a lot. Cole was stronger than he ever was before.
And now he's their biggest target .....
In this story, Cole must face the Queen of Ghouls, otherwise the Realm of Ninjago will fall into the hands of Evil...
