Expansion takes place in the future, Il Mheg < Ala Mhigo

This is presumably a few centuries to millennia after an apocalypse. Of course it isn't going to look the same. We can't even be sure that specific geographical features would look the same. But, Il Mheg is mountainous, and so is Ala Mhigo, so that renders the theory plausible at least.

By that logic you could say anything is any other thing. Ishgard's kind of like a snowy future Skalla, isn't it? They're both made of rocks. Maybe the Dawn Throne in the Azim Steppe is Amdapori because they both made a lot of dome-shaped things. It seems like a massive stretch.
