This part of the world is where most of the camapaign's adventures have taken place. From the Great Mountains west into the forests beyond the source of the Chandler Cowles River this area encompasses a huge territory with great changes in geography and population.
Some areas are mostly civilized with a large scattering of settlements by Humans, Demi Humans, and Humanoids. While not always friendly there is always the chance of shelter and groups or communities.
Contrary to what those who live in the civilized areas believe sometimes there are large stretches of land 'out there'. These tend to be the places that adventurers make their living. These areas are for the most part untouched by civilized people (with some small exceptions) and anyone who travels them does so at their own risk.
