Another doozy... The early references to 3 bring to mind mask Mask of the Third Man and Hawkmoon... "U" shaped conductor is throwing me off pretty hard... High pitch and low pitch makes me think of the Deathsinger and Gorgons... At the same time I'm almost leerily of it meaning pitch as in to toss... The final but about reality makes me think it has something to do with the vex.
