Fourteen hexes north, two northeast of Alakran.
Breathing poison while he lived and negative energy exhalations in his unlife, Dragotha left his favored preying grounds north of his lair a toxic zone. Their hazards persist even today. The place is not barren - fauna and flora can be found in relative abundance, but the animals are stunted with a strange sheen to their skin, the plants oddly twisted and crimped.
Food or water taken from the area does 1d6 poison damage on a taste, or on a full meal or drink, 3d6 poison damage and save (CON, DC 13) or take 1 level of exhaustion. Two hours of travel in these gray hexes has the same effect as a taste, and eight hours, the same effect as a meal.
