Varn Campaign World
Fela Thalor is a grey-elven polity of the eastern portions of Varn. It lies in the middle (heightwise) regions of the tall rainforest whose canopy is the Cuauhtla nation and whose floor is ruled by the centaurs; the borders of Fela Thalor also extend to the temperate forest north of the jungle. (Alternately, the temperate forest is the heartland of the grey elves. Still working out the details.)

Ruled by a Matriarch.
