Here is what I found in the 4e FR Campaign Guide:Aren't the Primordials imprisoned on Abeir by Ao? I'm just curious as to how they manage to do this. I like the idea of the evil gods freaking out, I might steal that, but their response in my version would probably be different.
"✦ The Elemental Chaos: The primordials dwell in this roiling storm of raw creation. This section offers a brief tour of major primordial realms."
The Elemental Chaos provides essential building blocks for all matter in the cosmos, the primordial seed of all that is. The gods fear this wild plane of unimaginable extremes, and they respect the primordials that call it home. The few primordials that remained in Toril when Abeir split away never fought the gods as their fellows did. These primordials are sometimes worshiped as deities despite their elemental origin
The Elemental Lords
Five primordials rule realms within the Elemental Chaos. All but the chaotic evil Bazim-Gorag are unaligned.
Akadi: The Queen of the Air is the mistress of flying creatures and all that takes to the thin air. Her airwalkers teach that wisdom can be found only in trial and error, a foundation for faith as thin as the air that their mistress embodies.
Bazim-Gorag: The Lord of the Pandemonium Stone (see the sidebar) is an ascended batrachi dedicated to pure chaos. He is chance incarnate, invoked by the powerless, the gamblers, and anyone who has lost hope in anything but an impossible twist of fate.
Grumbar: The Lord of the Earth is a being of stone and dirt, the foundation upon which all else is built. The earth makes no choices—it simply is. His earthwalkers resist change in any form.
Istishia: The Lord of Water is the embodiment of the constantly mutable nature of water. Not interested in Umberlee’s storms or Valkur’s sailors, he is an aloof and uncaring being.
Kossuth: The firewalkers who revere the Lord of Fire espouse the cleansing properties of flame and its role in the renewal of life. Kossuth is most often appealed to by lay folk as they watch their homes burn to the ground. They find him entirely uninterested.
Seven Lost Gods: This term has been used to describe different groups of powerful entities at different times, sowing confusion even among learned sages. Some of these so-called “lost gods” might have been primordials. One group of beings that could fit this designation includes Dendar the Night Serpent, Kezef the Chaos Hound, and Borem of the Boiling Mud. "
