So about that last one I did, note that I put ninjago near the US. The age of imperialism was when many western nations (like the US, UK, France, Germany etc.) would colonise and set up spheres of influence in places like Asia, literally all of Africa except for Ethiopia, Australia, and other places. Past ninjago, like most asian countries, looked much more classical and not modern. I think that ninjago would become modern from becoming a colony of a western nation. And with the location i put it on in a map, that nation would be the US (definitely not bc im from america and they speak english in ninjago lol). Like most other colonies, they became free after World War 2 (I'll put a bit after this).
