Swamp of Oblivion (Plane of Ooze)

The border region between the planes of Water and Earth is a horrid swamp where twisted, gnarled trees and thick, stinging vines grow from the dense muck and slime. Here and there within the Swamp of Oblivion (also called the Plane of Ooze), stagnant lakes and pools play host to thickets of weeds and monstrous swarms of mosquitoes. The few settlements here consist of wooden structures suspended above the muck. Most are built on platforms between trees, but a few stand on stilts driven deep into the muck. No solid earth underlies the mud of the swamp, so houses built on poles eventually sink down into it.
It is said that any object cast into the Swamp of Oblivion can’t be found again for at least a century. Now and then, a desperate soul casts an artifact of power into this place, removing it from the multiverse for a time. The promise of powerful magic lures adventurers to brave the monstrous insects and hags of the swamp in search of these treasures.
