The fifth and most primal layer of the land is the Aethersphere. It follows the Terrasphere, Mythosphere, Mnemosphere and the Akasphere. It is the place where the primal elements are perceived in an ever-shifting fluidity. It is the core elements of form itself, that from which every other form is made. Here lay the components of the grand archetypes which lay in the Akasphere, their essences revealed to be a medley of elements in constant change.
At the level of the aethersphere the maps of the Mythica dissolve into their primary components.
