The capital city of the Yalen kingdom was located to the east of Kera, Arthur's hometown.
In-between lied many cities, strongholds, and camps of varying sizes covering the ever-stretched wilderness of the kingdom.
Farming was taken care of by strongholds that defended the fertile lands from attacks.
Villages, like the one Arthur found in the middle of the mountain range Rovero, were rare and didn't exist unless they had special means of defending themselves against monsters, like the ring of illusions.
Nonetheless, the Yalen kingdom stretched wide and far as Arthur could see from his seat in the plane.
Although mounts were also used for long-distance travel, it was of a lesser-luxury than planes that used mana as fuel.
Ever since the industrial revolution of mana, fuels like diesel and gasoline were buried in what is called The Era Before Magic.
Mana was a renewable source of energy that could be used at the same time as being 'resupplied' the world.
