Pandemonium

Also known as the Great Maelstrom for the wild storm of the same name that rages there, the plane of Pandemonium is a place of constant change and the source of most of the chaotic energy that flows across the Sea of Dreams. The plane is mostly uninhabitable due to the hostile conditions but certain creatures amazingly have been able to flourish there in spite of this, namely the Slaad, a race of frog-like brutal creatures that relish in causing chaos in any way that they are able.

The Great Maelstrom is a massive storm that ravages across the plane, fueled by the elemental energy released when the Shards that make up the Elemental Conflux collide with each other.

Pandemonium is located on the outer rim of the Sea of Dreams, pressed against the barrier of Ethereum that separates the Inner Realms, which is made up of the Sea of Dreams and everything residing within it, and the Far Realms.
