Oath to Order

The Oath to Order is a magic song taught to Link when he rescues the first of the Four Giants from Woodfall Dungeon during his quest to save Termina from Majora's Mask 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 -- If you saved all four of them -- come and hold up the Moon for the player to enter and defeat the evil inside Majora's Mask.
