It is composed of three Ornate Pedestals. Initially, two of them contain an Iridescent Gem each and the last one is empty. Attempting to place other gems will result in a failure announcement, but placing another Iridescent Gem will activate the switch and power Archive Chandeliers, the Archive Orchestrina, Ancient Guard Posts, and the Fountains of Knowledge. Activating the switch for the first time will immediately set the Nightmare Cycle to the Nightmare Phase accompanied by a sound that plays in every underground biome. Additionally, Nightmare Ramparts will permanently spawn in the Lunar Grotto. The power can be cut again by removing an Iridescent Gem.
