The Deadwoods

From publisher blurb: The Deadwoods hex is another in the Lake of Abominations series. It features a spur of the Darkwood called the Deadwood, ruled by an undead treant, and a small goblin village established at the edge of the Deadwood, hoping that their proximity to such a fell place will grant them a measure of safety from a larger goblin village to the north. It also features two goblin race-as-class options: the goblin warrior and mage, as well as rules on goblin demographics.
