Auril

The Frostmaiden and spiteful, apathic Godess of frost, wind and Rime. She is the neutral evil goddess of winter and cold in the Faerûnian pantheon. The embodiment of winter's cruelty and all its deadliest aspects, Lady Frostkiss had a heart of ice to match her lethally cold beauty, eternally preserved beneath a sheet of rime. As Talos, leader of the Gods of Fury, eroded her power over snow storms, The Cold Goddess made her season even more frigid to remind the people in the north who controlled the cold.
The Frost Sprite Queen was additionally seen as being synonymous with the Queen of Air and Darkness by some communities of fey, such as those of the Shiverpine Forest in the Deep Wilds.
