The Poison Forest is a land that is perpetually on the edge of death. The water is tainted, plants stunted and poisonous, and the animals are sick and appear to be in a state of perpetual decay. Most believe the land is tainted by the ash that blows in from the Wastes, which lie a few miles to the west, but nobody has uncovered the truth of the matter.
The forest is a source of True Wood, and a few brave and desperate souls eke out a living on the edge of the region. These settlements are frequently plagued with the same grey depression as the nearby city of Jerris, and those who live in the area keep an eye out for signs that whatever taints the Poison Forest does not infect their own lives.
