The Great Marsh of Fablehaven is a mysterious, large expanse of soupy terrain that's one of the most perilous, least explored areas of the Fablehaven preserve. An abundance of moss and vines burden the trees, and shreds of mist swirl near the ground. The warm air reeks of decay. Fuzzy mushrooms and slimy rocks decorate half-drowned islands. Various paths run through the marsh, some real, some counterfeit. Explorers must beware of the Swamp Hag, who uses fake trails to lure travelers to their demise.
