Darklands

Across the Casdo Ocean from Vailya is a continent only named "the Darklands". The name is given by explorers from Casdomildei, as the natural inhabitants have not named the continent and refer to it only as their homeland. The Darklands themselves are plagued by a civil war between several anthropomorphic Auran species. There are three An Settlements; Dawn Harrow, the largest and most well established of the three; Stormwatch, sitting on the steep cliffs north of Dawn Harrow, steering ships toward Dawn Harrow; and Black Mission, a trading post between the An and native Agadae.
Of native species fall into two castes, The Alpha and Beta castes; Alphadae and Betadae respectively. The Alpha castes are the civilized and have developed culture, permanent settlements, and other traits you would associate with the civilized world. The Betadae are partly intelligent, but are either subservient or herded by the Alphadae. One exception to the Betadae classification is a toppled Alphadae, the Roadae, kept as servants and slaves by the Agadae Alpha Caste.
The continent itself has a warm and tropical climate. However the continent is covered in a constant black overcast that varies from pitch black to a dark grey that stifles large overgrowth. The color is fueled by the ocean's supply of water and sporadic volcanic activity, mixing the water and ash into toxic, low-hanging clouds. Alphadae and most Betadae are accustomed to the air quality, with some herded Betadae cultivated to have adverse affects to the air to keep them subservient.
