The Elemental Chaos is the raw material of creation, that from which the universe arose. Untouched by the stabilizing divine influence that formed the world into a more or less permanent state, the Elemental Chaos is a roiling tempest of matter and energy. At times, areas coalesce into coherent shapes and terrain, but much of it resembles a stormy sea of churning destruction. The Chaos is at once the foundation of the world and the greatest threat to its existence. By its nature, the Elemental Chaos seeks to pull the created world into its embrace, and return it to its component parts.
Most of the inhabitants of the Elemental Chaos share a primal drive toward entropy. Many are creative in their own ways, building structures and civilizations, tearing them down, then beginning anew. Demons, however, driven by an insatiable thirst for destruction, seek to draw the entire universe into the vortex of annihilation that is the Abyss, their home.
No traveler to the Elemental Chaos could mistake it for any other plane or world in the infinity of existence. The “ground” might be bare elemental rock, hardening magma, a smooth sheet of ice or glass, or a field of jagged crystals or crumbling ash. Above, mountains of stone drift through the air or float on currents of lightning, while storm clouds collide with sheets of flame. Not far away, the ground comes to an end—a sheer cliff drops into an infinite abyss, or a river of magma cuts across the landscape. Another island might drift nearby, perhaps far below or just above—but sometimes on a collision course. The resulting cataclysm annihilates both landforms and creates something entirely new.
The substance of the Elemental Chaos is raw matter, unworked and unrefined. Air fills most expanses between masses of elemental material, making the majority of the plane at least theoretically hospitable to travelers from the world. In places, though, air is a hazard—swirling in ceaseless whirlwinds that grasp and never let go, or flowing as a liquid, cold enough to freeze fire.
