Westmark is one of seven original Duchies of Eldara.

When King Eldan established the Kingdom, he was backed by seven powerful Vassal Lords, all of whom were rewarded with large territories to govern. The seven stars on the Eldaran flag represent these seven great houses.

Later, following the Cataclysm, King Damion Irazadi subdivided each Duchy into three smaller Dukedoms, so the present-day Kingdom of Eldara has 21.

Half of the Westmark lands were given to the newly created Duchies of Jandara and Savoy.

Today, the Duchy is ruled by the Lady Nalia of the House of Skorupio.
