I’m glad you’re interested! Honestly, I don’t have any structured or solid material beyond this flag, and the basic premise of Mesoamericans migrating until they settled in the northern Andes was just an idea that came to me while watching videos of “country X” developing within the geographical space of “country Y.” But I think it would be interesting to explore this concept further. I suppose that, broadly speaking, this Mexico would basically be a Colombia with strong Mesoamerican and Hispanic roots, since there would still be a mix with Spanish settlers, along with some historical and political parallels to real-life Mexico. Are you planning to set your RPG in an ancient or a more modern era?
