This Dahon is NOT the Queendom of Dahon.
This is an alternate-historical FanT nation, set on a timeline where the Japonic incursions of the sixth century AD failed to displace the native powers at their weakest and so bring peace, succeeding only in occupying the mostly unwanted eastern third of the main island. As of 2018, no less than 5 roughly equally powerful nations vie for supremacy over the entire archipelago.
