The Nation Archipelago is made up of two separate groups of islands. The first group is in the east of the archipelago and consists of seven islands, which together make up the state of Seven. A large number of islands are named after countries, hence the name of the archipelago. The second part is formed by Asian and Truth Island, making up the state of Clymene. The famous Rock of Arnmod is located about 60 feet off American Island in the archipelago.
