A particular form of Spellsong is the Grand Chorus, celebrated by the priestesses of the temple of the Promenade of Eilistraee. This is the greatest ritual of worship to Eilistraee, ""an ever-changing song of celebration led by a senior priestess who guides the song with an overriding theme or melody"". The Chorus could bring into being beams of moonlight, which intensity grows with the emotion of the singers. If such radiance meets with real moonlight, Eilistraee's power will make it so that all beings and items that the priestesses are touching or carrying while singing can, at will, be transported along a web of moonlight for as far as it reaches. In that way they can move from the location of the Chorus to any place on the surface lit by the moon and it is through this spell that the priestesses would travel to the surface for their missions.
