Sky Keep

The Sky Keep is the final dungeon in Skyward Sword. It is located underneath the Statue of the Goddess in Skyloft. It has eight rooms in total, and to navigate them Link must alter the building's structure by using several terminals throughout the dungeon which operate much like a sliding puzzle. Six rooms are designed in style and theme of each of the other six dungeons in the game, three of which contain pieces of the Triforce which Link must collect. The other two rooms consist of the entrance and the room where the miniboss, Dreadfuse, is fought for a Small Key.

Link discovers Sky Keep after successfully passing the Silent Realm challenges of the Goddess. Afterwards, Link recieves the Stone of Trials, which he must insert into the empty hollow of a bird statue that contains an identical stone in one of its eye sockets. The statue fires a cannon ball, which shatters parts the land mass where the Statue of the Goddess sits. Link can then use his clawshots to enter the dungeon.

After the Triforce is completely collected, Link wishes for the destruction of Demise and so the Sky Keep breaks away from Skyloft and lands in the Sealed Grounds, where it is revealed to be part of the Sealed Temple. When it falls, the Sky Keep destroys The Imprisoned by crushing it.
