Pandemonium
From Threesong
The Iron Aether, commonly known as Pandemonium, revealed its true nature when somebody finally found the volume switch; It plays heavy metal at merely concert volume, and is a base of operations for Stance's faction, xXxRiverxofxLyexXx, who worship the Gods of Metal at their tombs in this plane. These gods are popular among the gith, who account for about a third of Lye's members. The plane sometimes manifests in the sky above concerts in other planes: the catwalks of the Iron Aether. Founding myth: The Quiet King and the Gods of Metal
