Limbo

The Ever-Changing Chaos of Limbo is an Outer plane in the Great Wheel cosmology model that embodied the chaotic neutral alignment.

The plane of Warrior's Rest in the World Tree cosmology was similar to Limbo in many ways but not quite as morphic. The batrachi formed a realm in Limbo called the Supreme Throne which became its own plane in the World Tree cosmology model. Limbo was lost during the Spellplague and may have fallen into the Elemental Chaos.
