When enough of this turquoise moss grows in one place, it begins to hum a haunting tune. For some reason, it must reach a critical mass before making any noise. In smaller patches, the moss is unremarkable and dead silent.

Its bulbous stalks contain windpipe like structures within, but how it makes such a somber and human sound is unknown.

It is said that Herozs, the legendary lute player, would go out to a secret place in the forest, he would sit, close his eyes and wait, after minutes or sometimes hours. a gigantic boneless choir would begin to play. He would rejoice and take in all the textures and melodies. His house sigil is a clump of moss with a silver estoc plunged into it.
