The Quasi-Elemental Plane of Dust
The Quasi-Elemental Plane of Dust is a place of entropy and erosion, where things slowly grind down into nothing but dried dust. Formed by the intersection of the Elemental Plane of Earth and the Negative Energy Plane, it is a vast dark expanse filled with swirling clouds of dust borne on barely-perceptible air currents. Gravity here works like it does on the Elemental Plane of Air, where one picks their own ‘down’ direction. However, this is the only similarity with that pleasant and easily-habitable plane.
As with other para-elemental and quasi-elemental planes, the tenuous borders between the planes bleed through each other to form differing environments. In the Tumbling Rocks, dust particles clump together to form larger stone-like masses that are constantly moving and grinding against each other, the stones getting bigger as one nears the Elemental Plane of Earth. In the other direction, the Storm of Annihilation forms where the Negative Energy Plane impinges on Dust, creating a swirling storm that can literally cause matter to explode. The border with the Quasi-Elemental Plane of Ash is not much better; it is known as the Wasting Place and is a region where eroding dust and freezing ash mix. The Consumption is the border with the Quasi-Elemental Plane of Salt which is on this same plane, where any water in the air, or in any living thing, crystallizes into the tiny scintillating granules that characterize the area. The Oasis of Filth is the border with the Para-Elemental Plane of Ooze, and is a disease-ridden mire. Finally, the Sands is an area of cooled volcanic sand near the Para-Elemental Plane of Magma, very fine sand that will foul any machinery that is brought through the area.
