The Elemental Chaos is the fundamental plane within which are contained all of the former elemental planes and energy planes as well as the planes of Limbo and the Abyss. A tempestuous sea of ever-changing terrain and clashing elements, with stability only enforced in isolated locations, the Elemental Chaos is ruled over, at least in name if not fact, by the primordials and is the equal and opposite of its divine counterpart, the Astral Sea, as the primordials are the opposites of the gods as demons are to devils.
In spite of its chaotic and dangerous landscape most parts of the Chaos are relatively easy to travel through, or at least so much as most other planes.
The Elemental Chaos has existed as long as the Astral Sea, but prior to the Spellplague was unknown to nearly all inhabitants of Toril. During the sundering of Abeir from Toril the primordials, with a few exceptions, who inhabited the Chaos lost their influence over Toril and the surrounding space and were driven from the local multiverse into a separate and parallel existence, where Abeir also dwelt. Only with the Spellplague and the subsequent swapping of material between Abeir and Toril has the Elemental Chaos again become a part of the local cosmology, reabsorbing the local elemental planes as well as the Abyss and Limbo.
Though most of the Elemental Chaos is an ever-changing landscape defined by chaos and unpredictability, there are planes within the Chaos that have a more defined set of stability. These sub-planes, called realms, are formed through the will and power of mighty elemental beings, often primordials but including other denizens of the Chaos as well. Within these realms a sort of order is maintained, often reflecting the nature of its creator and ruler. This is not always entirely true and the Abyss, for instance, is as chaotic and dangerous, if not thoroughly more so, than the rest of the Chaos.
