Under the dark sky, Aither's forces reign supreme. There is no human who can stand against him and his army of undead beings. He fells his enemies and conquers the neighboring territories, earning him untold honors in his homeland. Even slanderous names such as "the Cursed Knight" do not sway him from the path he has chosen.
In Greek mythology, Aether (Æthere, Ancient Greek: Αἰθήρ, pronounced [ajtʰɛ̌ːr]) or Aither, also known as Acmon, is one of the primordial deities, the first-born elementals. His name means "light" in ancient Greek. Aether is the personification and elemental god of "the bright, glowing upper air of heaven - the substance of light". He embodies the pure upper air that the gods breathe, as opposed to the normal air (Ἀήρ, aer) breathed by mortals. Like Tartarusand Erebus, Aether may have had shrines in Hella, but he had no temples, and it is unlikely that he had a cult.
