(A/n: Short prologue I know...)

Nobody knew the truth about Morro's defeat.

They all assumed he died with the Preeminent.

That wasn't him, in fact.

Because ghosts can mimic, it was a different ghost disguised as him.

Morro knew he'd be defeated and abandoned somewhere, and no one knows where.

Morro was clever, so he could be anywhere and observe them from afar.

He was a crafty ninja.

All of the ninja thought Morro was the one who fell, but they were all wrong.

The Ninja all planned a party day, but they will have to wait two months for it to happen because things could go wrong.

Nothing could possibly go wrong, or could it?

Things can happen at any time in NinjaGo.
