Oath to Order

The Oath to Order is a magic song taught to Link when he rescued the first of the Four Giants from Woodfall Dungeon during his adventure to save Termina from Majora's maks and the falling Moon. It is used to call the Four Giants, but it only works if you call them from top of the Clock Town past 12 am on the final night, once called, the Four Giants will come and hold up the Moon (If you saved all four of them) for you to go to the Moon and defeat the evil inside the Majora's Mask.
