I really like how the potential of whatever might be hidden in the tomb is the draw for risking the dangers of the canyon. On that note, this seemed to be the case from what I read, but once someone is conscripted to guard the tomb, have they lost their mind to the music forever? I really enjoyed that the favors owed to each cave dweller were not in the section of the tomb you would associate with them, it was nice to see the juxtaposition of their distrust for each other with their unknowing dependence on getting what they desire from others.
