A black morass, Marratu Swamp's a suddenly overgrown area in the otherwise desolate Tohu Expanse. Emptiness gives way to dense underbrush, sub-tropical foliage, and aquatic pokemon gathering in the swamp's dark waters. It was never much of a town, but the outcaste of Tohu Expanse called the swamp home. They had a village, but it was destroyed by the scourge. The world doesn't care about them, but there were no survivors.
