Everlon is a Duchy of the Iskari Kingdom of Iskandar. Its capital is the city of Natharos.

Everlon was once a regional Thaindom of the Kingdom of Urland. Its last Thain; Kennard, was overthrown by Idarius Harrow during the Forty-Years War, and the city became part of Iskandar.

Since that time, the duchy has been ruled by the powerful House of Harrow.
