Aerdrie Faenya is the elven goddess of Air, Weather, Freedom, Impulse, Fertility, and Birds.
Aerdrie appears to be a tall, elven woman with feathered hair and eyebrows. A pair of large bird-like wings, with feathers that constantly change color, sprout from her back. The lower half of her body vanishes into a misty whirlwind, so that she never appears to touch the ground.
Though a member of the Seldarine, Aerdrie Faenya is also worshiped by ki-rin, lammasu, aarakocra, and avians. A small number of air genasi close to elven communities also take her as their deity. She is the primary patron of the avariel, or winged elves. Aerdrie particularly loves, and is loved by, the avariel, although many elves who wish for the prospect of good weather and gentle winds also worship the Winged Mother.
Aerdrie's realm, a floating palace called the Aerie, shifts across the border between Arborea and Ysgard; sometimes it is found in Arvandor and sometimes in Alfheim. Flying processions of eagles, falcons, and other flying creatures can fill the sky around her palace for hours, and when they find perches they can fill entire forests.
