Jesse's World 5th Edition
General: Bramblewood Marsh is relatively large expanse of wetland in the southern Witchwood. Situated in a shallow lowland surrounding four large ponds (or small lakes, depending upon your perspective), the marsh serves as a drainage basin for a small, unnamed river that flows out of the Barrier Peaks. The marsh is dominated by fields of thick, green grasses, deep pools of water, and dangerous pits full of sucking mud. The edges of the marsh bleed into the surrounding Witchwood, creating dense, more swamp-like areas which combine the worst aspects of the Witchwood and the Bramblewood Marsh into one thoroughly unpleasant whole. The only distinguishing landmark of the marsh (aside from the looming presence of the nearby White Plume Mountain) is the aptly named Sunken Tower.
Creatures: The marsh is home to many of the typical denizens of the Witchwood and also adds clouds of biting insects, large, poisonous snakes, carnivorous plants, and aquatic oozes to the mix, making it one of the most unpleasant (and deadly) places in the Witchwood. Maybe even in the whole valley. Adventurers and explorers routinely avoid the place, finding its environs to be more trouble than they’re worth. Recently, those that do venture to the marsh have reported seeing a large shape winging overhead or slinking through the waters, a shape that can only be described as ‘draconic.’ Whether the creature is merely a large wyvern or some variety of true dragon, chances are the Bramblewood Marsh has just become an even more dangerous locale.
