The Southeast of Thessan is covered with dense temperate rain forest. Fernhollow is home of the Kender and it is here that the Halfing race had their start. The duchy of Fernhollow is a paradise for the small folk, consisting of dense forests, mossy hills and green fields. Rarely will any hill not have a door in it and if it weren't for the trees and shrubs, the whole region might be mistaken for a town. Fernhollow once held a road south into Yod, however orcs patrol a massive stone and earthwork fortress called Vorg's Wall which now blocks off the mountain pass.

Fernhollow has been strongly effected by magical forces in the past. Openings to the World Cavern and fey controlled regions have infused the region with wildmagic energy.
