This plane of existence, like the others, was created in the beginning when the Great Bard sang everything into existence. It is intended as a barrier between the mortal Material Plane and the Astral Plane. This plane surrounds the Astral Plane, serving as its barrier.
When the fifth Ishu ascended, he traveled beyond the stars and found himself in an endless sky where he was met with a boat made of clouds. He made his way through the Plane of Air until he found himself in a colossal ocean. On the surface was a whirlpool which led him to the bottom of the ocean. There he found a giant wall of earth with many dark cave systems but one cave system had crystals that illuminated a path for him. He made his way through until he got to a burnt land with rivers of magma and clouds made of smoke. As he walked there, the ground cooled where he stepped and the sea of lava split, allowing him to walk through it. He continued until he got to a star that emitted a harsh, blinding light. Using his newly gained powers, he darkened the star's light from harsh to gentle and became one with it. He crafted a crown from the golden light of his realm. He then built a grand palace on the edge of the star.
