THE PARAELEMENTAL PLANES
The planes of Smoke, Magma, Ooze and Ice lie between the main Elemental Planes. They are realms of duality, in which two forces combine to make one. Less known and less traveled than the four elemental planes, they also hold some native inhabitatnts.
The Plane of Smoke is where Air and Fire meet. This plane's filled with foul smoke. A body can't breathe here without magical assistance; the hot atmosphere is completely saturated with choking clouds and noxious fumes. Like on the Plane of Air, down is relative and beings have to fly in order to get around. Few are Earth pockets. There's little native life here to do any building, except for a Place called the Chocking Palace, where Ehkahk the Smoldering Duke rules over smoke mephits and other fume-based creatures.
Fire and Earth combine to form a plane more inhospitable than the Plane of Fire, the Paraelemental Plane of Magma. The efreeti and dao meet here to trade and few other creatures of earth and fire dwell on this plane rather than their own. Otherwise, lava mephits are all a body's going to find here. A basher named Chilimba claims dominance over the entire plane and nobody seems to care enough to challenge him.
Earth and Water merge to form the Paraelemental Plane of Ooze. Mud and slime fill an ocean with no end and no direction. Conditions are like those on the Plane of Water, but the substance here is opaque and thick. Nothing can survive here except ooze mephits. No known cities or palaces exist, even in the few pockets of pure water of fresh air. Seems that the only use of this place comes from its function as a prison; banishments have lead to this plane's pseudonym, the House of Chambered Madness.
Water and Air form the Plane of Ice, wich has a navigable surface and breathable air, and nothing else but ice and snow. Immense glaciers, ice flows, snow fields and frozen seas make up the entire landscape. At the heart of the plane, Cyronax rules over all ice elementals and mephits, hoping to extend his influence eveb onto other planes. This plane produces a rare resources called eternal ice or unmelting crystal; it 's extremely hard and almost unbreakable.
