Plan
There was a limit to the amount of militaristic capital that each of the nations was willing to spend on the expansion endeavors in the Serevian Dungeon. This limit had to do with the loss of the assets suffered by nations in conflicts with other nations weighed against the profits made by the extraction of the esoteric resources from the territories in the Serevian Dungeon.
Although Martial Apprentices were meant to be deployed in conflicts, no nation was willing to stake too much. The number of Martial Apprentices that were qualified to be deployed in the Serevian Dungeon was not too high. After all, only the Martial Apprentices above grade seven were qualified to be deployed in the Serevian Dungeon. Otherwise, they were simply too weak.
