The Tyranny of Dragons: Dawn of Heroes
Our Lady of Silver, the Moonmaiden, the Night White Lady
Selune is thought to be among the most ancient of Faerun's deities. Most humans in Faerun consider the moon in the sky to literally be the goddess gazing down on the world, and the trailing motes of light behind it her tears. She is also a goddess of stars and navigation as well as motherhood and reproductive cycles. She is seen as a calm power, frequently venerated by female humans as well as by a mix of other folk: navigators and sailors, those who work honestly at night, those seeking protection in the dark, the lost, and the questing.
There are many legends about Selune, chief among them being the tale of the battle at the beginning of time between Selune and her sister, Shar. The Tears of Selune, the cluster of starry lights that follow the moon around the sky, are thought to be brought about by the goddess's joy, sorrow, or both.
Milk, a symbol of motherhood, is used in many rites performed by the worshipers of Selune, as are trances and meditation. Those who favor her typically set a bowl of milk outside on each night of the full moon.
