The Western Holy Empire of Divinia.
The Eastern Empire of Adania.
The Central Empire of Arya.
The Southern Arctic Empire.
The empires of the present era were composed of both larger and smaller kingdoms alike, all of which were under the ultimate rule of the imperial power.
The Kingdom of Grisha, one of the significant kingdoms of the Adania Empire, located in the far east, west of the Atlan Sea, was one of the largest exporters of marine life resources throughout the continent.
In its capital known as Adua City, an enormous warp gate—a technology architected by the innovative mages of magic towers and engineered with the assistance of the dwarves—caused a jarring sound as it pulsated, forming a bluish-white whirling portal before revealing dozens of expensive caravans engraved with the [Hero Academy]'s insignia.
Even if unrest or conflicts arose from kingdoms within the same empire, under the imperial law, territorial war could be invoked with a proper justification.
