Queen of Air and Darkness

The Queen of Air and Darkness was a powerful archfey who ruled over the Unseelie Court.

Description
The Queen of Air and Darkness had no physical form; her presence was merely felt in the Unseelie Court. If magic was used to see her, however, she appeared as a beautiful but terrible female faerie with angular features, bone-white skin, all-black eyes, and long black hair.

Possessions
The Black Diamond, sometimes called the Night Diamond, was an artifact of immense power and evil of unknown origin. It sat atop her throne in the Unseelie Court.

Divine Realm
The Queen of Air and Darkness ruled over the Unseelie Court, the divine realm of the fey pantheon of the same name, which accounts variously placed as being either in Phlegethon in Pandemonium or in the Plane of Faerie.

Relationships
The Queen of Air and Darkness reigned over the Unseelie Court, the foes of the Seelie Court. She was opposed by the elven deities of Seldarine, namely Corellon Larethian, Erevan Ilesere, Rillifane Rallathil, Sehanine Moonbow, Solonor Thelandira, and Angharradh. To them, she personified the corruption that could grow even in those of fey lineage.

Auril the Frostmaiden was believed to be synonymous with the Queen of Air and Darkness by some communities of fey, such as those of the Shiverpine Forest in the Deep Wilds.

History
Once, the Queen of Air and Darkness was the sister of Queen Titania, ruler of the fey, in the land of Ladinion. But one day a group of dwarves, who had been mining in a mountain to the south, brought to the Seelie Court a great, ten-faceted black diamond they had found as a gift for the fey queen. However, Titania was away swimming that day so her sister accepted the gift. This diamond began to corrupt her, transforming her nature, and one day she took the diamond and other magical treasures and left in a chariot of smoke and fire that was said to have appeared out of the sky. Some time later the mountain that the dwarves were mining exploded, slaying the dwarves and causing sickening smoke to cover the land.

Worshipers
She was served by unseelie fey, including bramble faeries, quicklings, and spriggans. She was also known to have a fondness for yeth hounds and hell hounds.

The glouras, fey beings of the Underdark, had ties to the Queen of Air and Darkness and the Unseelie Court.
