Summon your wind-up Dalamud minion. Do not attempt to pry open under any circumstances.
After Dalamud's fall, a wealthy Ul'dahn noble commissioned a famous troupe of musicians to write a dirge for the heroes of Carteneau and play it across Eorzea so that the deeds of the fallen would not be forgotten. This wind-up model of the red moon has naught to do with the dirge.
