Mantle however is often off the radar for Atlas, and even then they'd have to have border patrol for an entire continent, which I doubt the whole military would try to do. Meaning more than likely, the Kingdom, which is only the capital really, is what has the lockdown.

Mistral itself isn't the entire continent of Anima, its the city. The villages are often self-governed, but the Council has final say. Even then, they can easily break off and self-govern as was the intent behind Oniyuri.
