Located next to the Vagoth Forest, the capital of the Empire of Dixon, the city of Jeffer, was situated slightly eccentrically in the middle of the empire. Built over a 70th-floored dungeon, the Imperial Capital was the biggest city, in terms of area, on the continent until recently.
The Imperial Capital was a melting pot of races and cultures on the continent. Housed over three million people, the city of Jeffer was undoubtedly the densest and most populous settlement in the landmass.
Infested with countless monsters, like vast and dense forests, dungeons were a risky way to earn a fortune. When a certain condition is met, diving into a dungeon could be the safest way to make a living at the same time.
Many individuals attempted to conquer the dungeon like the demon lord eons ago. All conquests failed until the hero, who ended the rule of the demon lord on half of the continent, managed to capture the dungeon. The hero then became the first emperor of the empire.
