He has round golden eyes and waist-length golden hair tied into a braid. Aether harbours a deep hatred for the Archons and Celestia. Beneath a veneer of calmness and humility, Aether is a calculative, domineering and dangerous person, despite his deceptively angelic and innocent appearance. He wields every element in Teyvat, and is likely one of the strongest beings in Teyvat. Aether is skilled in every field, from cooking to alchemy. He enjoys fishing and collecting flowers.
