Selûne, was the name of Toril's only natural moon. Seen from Toril, it appeared to fit within the size of a human fist held at arm's length. It was quite bright on a clear night, able to cast pale shadows.
Selûne was followed in the sky by the Tears of Selûne, a constellation of very small celestial bodies that was often identified as composed of nine stars, but which in reality consisted of hundreds of asteroids.
