The Remnant Dynasty is broken into 3 major regions.
The home of the proud orcish clans, Baile Duchas is a wilderness of forests and hills at the north-eastern edge of the Kairen Mountain range encircling the Nocthian Plateau. The major city is Gor'osh.
The central region is really two separate regions--Safehold (the plains and hills) and the mountains themselves. The major city here is Lyodanoir, the capital. The newly-constructed Winter Wall blocks a key choke-point against monsters from the Nocthian Plateau.
The southern region is home to the largest population of goblins. A center of industry has sprung up around Byarsha.
