The Realm of Death

After a long imprisonment under the ground, the Realm’s greatest affinity is with the earth. It is for that reason that the central meeting place for the Thall is a network of caves, stretching miles into the side of a large knoll. Almost completely devoid of sunlight (there are some small hole in the roof of the cave network), very little can grow. Moss and lichen thrive, but in the deepest caverns there is nothing but the drip, drip, drip of icy water, and in some not even that.
The main meeting cavern is spectacular, but only occasionally. When the full moon shines through a fissure in the roof, it illuminates the cave in a beautiful, and to some slightly eerie, light, magnified and reflected a thousand times by the shining water droplets hanging from stalactites and resting on stalagmites.
A warning, though: stray too far from the beaten track in this earth labyrinth, and you could be lost down in the dark forever… if you last that long.

This land cannot be claimed; it is a meeting place for all Thall, who side with the Realm
