No offense or disrespect, but when you said homeworld and wallworld, you got me thinking of Steven Universe, since they use homeworld.

Anyway, even without the Colossal and Armored Titans, it seems more like the original family of Reiss was a former enemy before Rod fell and Historia took control with a different objective that was not controlling the people.
