Lake Moss was an edible plant that grew in "carpets" in Deepwoods lakes. It had a spicy, peppery taste. It was grown by webfoot goblins in the Four Lakes, and also grew in Farrow Lake alongside rock-sage, water fennel and sweet-root kelp. A traditional webfoot recipe used them with fried fish, glimmer-onions and beck-lentils. It was mentioned in Doombringer.
