Why couldn't we have a non-magitek opponent invading Eorzea via long ship and horse back? I would so kill to see a game where we have horse back riding knights, long ships, castles, and good old magic backed King Arthurian forces flying fire breathing dragons going up against the Eorzean Alliance. Heck, make the enemy forces go full spanish inquisition!

They even have a good reason to invade: They see a land where people are riding giant yellow birds, talking to strange crystals, and dealing with all sorts of weird technology. This could lead to the entire horse driven nation going on a massive witch hunt to tear down all the madness. At least it seems like it makes more sense than having yet another manifest destiny story with a superior tech powered nation.

Go figure the seasonal event would get me going on this.
