The Mwangi Expanse
Most view the Mwangi as never ending jungle. Although they are right there is much more to the landscape than just that. There are savannahs, mountains, costal regions with hills and valleys, and of course there is jungle. The Mwangi Expanse is not made up of just one country or people, but of many isolated tribes and cultures. One of the defining features of the Mwangi Expanse is the thin veil to the Feywild. Because of this it has created Shifters among members of the Humans who live here. Also causing man eating plants and the creation of intelligent man eating Gorillas.
Sargava, rests within the Mwangi. A colony of multiple cities started by Cormyran interests. The colony has since declared independence from Cormyr with the help of bribed pirates and Varisian navy who saw this as a chance to hurt Cormyran interests. Sargava sustains itself through trade and cheap labor.
The Expanse is so large and diverse that it would be near impossible to map any of it and entire kingdoms have been swallowed up by the jungle waiting to be found. There is a lack of centralized government, Making the Mwangi a region, not a country. The most common religions are The Old Faith, worship of Zehir, and demon worship. The Silver Flame is a minority religion practiced almost exclusively by the Sargavans. The Aspis Consortium has great interest in the area. Due to the exotic goods and unfound treasures just waiting to be taken and brought to the rest of SAGA at large.
