Aether

Aether is the god of the upper air, the aether, that makes up the heavens. Aether (also known as akasha or spirit) is the fifth element of western alchemy, and it is the god Aether who gives it his name. Its hard to tell exactly who his parents are. Some insist he is the child of Nyx and Erebus, others that he rose from Chaos like Gaia, Ananke and Tartarus. His origin aside, he plays little role in mythology.
