The Aerilpar Forest, also known as the Wood of Dark Trees, both for its animated jungle and the dangerous beasts that prowled it, was located in Veldorn in the Shining South.
The Wood of Dark Trees was found between the Giant's Belt Mountains to the north and the Liontongue River to the south.
True to its name, the trees of this steamy forest were evil. It was widely rumored that the trees were some kind of animated monster created by a foul wizard. A host of monsters lived within the forest including flying snakes, dark trees, and a pair of mated Chimerae.
In the blighted Aerilpar Forest, there is a grassy hill known as the Mound of the Sleepless. No trees grow on it and no monsters dare approach it. Rumour has it that beneath the bound is a labyrinthine series of tunnels where time and space seem to twist and curve. The tunnels are said to be inhabited by umber hulks, thri-kreen, ankhegs and other bug-like creatures. These creatures serve Kharapaiz, a chitinous beholder prince, who dwells in the deepest parts of the labyrinth, guarding an artefact of unimaginable power.
