Analysis
The benefits of choosing the core territory at the edge of the Serevian Dungeon were clear. For one, the restocking and resupplying of necessary goods and supplies for the Serevian dungeon team became a lot more convenient for the Kandrian Empire. Otherwise, the routine supply shipments sent by Kandrian Empire would need to enter the Serevian Dungeon. Once it entered the Serevian Dungeon it was vulnerable to attack from hostile Martial Apprentices who had no qualms about attacking supply shipments in order to hind the Kandrian Empire.
Protecting the supply shipments heavily enough to deter the attacks from other competing nations would require an immense amount of Martial Art resources that would make the already expensive expenditure of the entire endeavor far greater than it already was.
