Tonga

Tonga is an island state part of the Islanders Schlentonist Confederacy, and it is the main capital for their confederacy. It is where the Attention Seekers live, in an ethnostate. On the island, they run several senate meetings and are the representative body for the other islands.

While Fiji is where Castle Fiji is and the king, Little Fiji, the Attention Seekers have more power in many ways, so the capital is on Tonga instead.
