The music is soft in most places in Crystalsong Forest, but not here. Though the Chamber is near the center of the forest, one cannot find it until one stumbles into it. That’s because it’s surrounded by a small maze of crystal spires. Yet if one turns just the right way he'll pass through them and into this shallow basin. The innermost spires tower above it and arch in slightly, forming a vaulted ceiling high overhead. The forest’s song is trapped here, bouncing from surface to surface and swelling with each impact, so loud one's ears ring. No other creatures are here, nor are there any indication of previous visitors. The music makes one believe that they are hearing life itself.LoM 98
