The Central Region was the place where most of the development efforts of the army were focused, mostly because it would be the center of their operations throughout the entire continent.
Unlike other regions, this place doesn't have any secret realms, and that's on purpose. This place would essentially become the federal army's headquarters. Sure, having a secret realm or two might accelerate the strength improvement of their soldiers, but that would remove their reason to explore other regions. Soldiers need to visit other places to keep everything in check and maintain the security of the entire continent.
Having no secret realms here doesn't mean that the Central Region's influence would be low. This place, after all, was destined to be the center of the federal army's activities for the entire continent, so it will definitely see a lot of traffic.
