When Its The Worse Case Scenario

A crossover between Ninjago and Heroes Of Olympus!
This is a headcanon of mine! So i decided to make it into a story!!! :D
It's all in Nya's POV, though it might change on certain occasions
So you know how djinjago started falling apart in skybound? Well the world is starting to fall apart now too. So now its up to Nya, the ninja, and the seven(plus Nico) to save it once again before it falls apart completely.
