Shuto

Shuto (首都, meaning "capital city" in English) is the capital city of the Empire. It is located on the whole island in the middle of the middle sea, Chūō Umi.

There are almost ten thousands inhabitants. Most of them are rich, work in the city and travel a lot.

There is no military except for the militia protecting the royal family.

There is an emperor who lives in the palace. The current one is relatively old and from a family that's been in power for decades. The emperor often invites a council formed by people from the four main cities to discuss important matters.

A legend says that underneath the island lives a monster.

The climate is temperate.
