“In the oldest tongues of the Ethereal Plane, the word Aetherion meant ‘Breath of Creation.’ It was spoken by the Six Ancient Gods when the first sanctums were forged from elemental harmony. The name was lost during the Void’s corruption, erased from mortal memory, and only resurfaced in divine visions granted to the Ethereal Walkers. To speak it is to invoke the promise of balance—a vow that the world can be healed.”
