The Aqumis Free State
The Aqumis Free State was founded in the early 4th Era, and is the youngest internationally recognized nation in Minecraftia. It is a tiny frozen island at the southern tip of the Southern Sea.
It was originally planned by Kaiser Von Dragestein as a theoretical place where people who did not wish to live in either Empire could stay. At the time, most of the island was Kythiran property. After several negotiations, both sides agreed to remove their claims on the island, leaving it politically neutral.
The Free State has no official leadership, and only has one habitable building. Due to its remote, frozen location, it isn't very hospitable. To add to this, the Kythirans placed bunkers and trenches, as well as having the Empire's only Arctic Proof marine ship continuously present.
