The capital of Oegesia wasn't far from the protagonist's village. If one rode a horse non-stop, it would take about ten hours to reach. In fact, this so-called nation was quite small, especially when compared to the ancient nations of China. At best, it could be likened to a county in Europe during the Middle Ages, perhaps even just a duchy.
The speed of the Green Goblin hoverboard was many times faster than that of a horse. In less than an hour, the group had traveled from the village to the capital. It was a majestic city built against a mountain. Although the main buildings of the city weren't very large, there were several villages on its outskirts. While these villages weren't particularly big, their combined population was substantial.
