What if Ninjago and Chima exist on the same planet?

Hear me out. I think Chima is a third main island in Ninjago. What if there was a third-god-like being other than the great master and the Overlord? He could be bluish and invent Chi. And in his islands, he made great lakes of Chi and had the animals drink from them. Maybe he is the Great Master's brother or something.
