Paraelemental Plane of Ooze

Between the planes of elemental Earth and elemental Water is the Paraelemental Plane of Ooze, also known as the Swamp of Oblivion. Close to Earth the rocks and dirt took on a clammy dampness. As you move toward Water, the density decreases to a quicksand-like state and then thinns out to muddy silt. Spells and devices that provides water breathing capability works in this plane also. Pockets of Water form an irregular bubble in the muck. Pockets of Earth are solid nuggets suspended in the ooze. The Paraelemental Plane of Ooze touches the planes of Earth, Water, Minerals, Steam, Dust, and Salt, and could be reached directly through the Ethereal plane. Ooze is the location of Ghaunadaur's realm, the Cauldron of Slime. The only other name that survives in lore related to this plane is Bwimb, another possible prince of para-elemental evil.
