For Ren:
The area is likely in the southern foothills of Mt. K as they move into the central plateau of modern day Tanzania. The lands are largely tribal controlled, but which one controls the area in question (particularly given the the vagueness of the directions and the fact that the lines on the map change often) you cannot say whether it is the Maasai, Mijikena, or some other tribe.
The list of fauna is extensive, really too long to list, from the typical savanna dwellers (giraffe, wildebeast...) and their predators (Leopards, hyena...), dozens of species of birds, to the apes that dwell in the jungles of the foot hills. The list really is too long to make. Your knowledge of paracreatures extends to the types associated with the typical species of the area.
