The Home of the Gods. The final resting place of Exalted souls. Long ago, this Plane Above was a powerful, ordered structure known as the Lattice of Heaven. This was destroyed during the Dawn War by the Primordials. Now it is a vast ethereal sea. Millions of miles separate the distinct Domains of the Gods, islands floating in this sea, each with their own natural laws and orders of being. Special ships travel at such speeds they can make the journey between domains in a matter of weeks. Most Domains are the home of a God or several Gods, either good or evil. Some Domains were once the home of Gods now deceased. In the sea, there is no gravity and air is not required. Anyone can float alone anywhere in the sea until they starve to death, and you can travel very slowly in any direction you want just by willing it. Githyanki pirates and strange, giant creatures ply the far reaches, treacherous to travelers.
It is difficult to travel between the Astral Sea and the World without powerful rituals or the direct invervention of the Gods.
