Gray Oak Night Talk

Before delving into the specific form of any empire, one must first establish an underlying rule that runs through all the forces in the entire continent: magic talent is extremely scarce. In this land, the number of core magisters that each empire can stably possess is locked at the level of "two to three hundred people." This is not a coincidence in the setting, but is determined by the origin of magic on this continent: the proportion of the population that can be trained to become formal spellcasters is roughly the same in all civilizations, and they all stay at an extremely low probability. Therefore, two to three hundred people is not the upper limit chosen by an empire, but the upper limit set by this world for magic itself. All the military systems, social structures, talent selection and political systems of the five empires are different answers that evolved around this hard constraint.
