Lorelei

Lorelei (ローレライ, Roorerai), the Composer of the Heavenly Notes, is the Spirit of Guidance under the element of Sound. Lorelei appears to be a young boy with his feet fading to a flame-like ephemeral substance. People living near Ariad Riverbed have heard Lorelei's symphony on full moons. He rests in the River of Songs.
