Bound Chest

From Zelda Wiki.org

The Bound Chest is a artifact from ancient times. Mentioned only in The Minish Cap, the story says how a hero was granted the Picori Sword and used it to seal all the world's evils inside the chest, using the sword to seal them inside.

Years later, in The Minish Cap, Vaati destroys the sword in an attempt to get the Light Force, releasing all the monsters at the same time. There is a possibility that the Bound Chest is also part of the pedestal that the Four Sword resides in, as the sword is said to seal Vaati and Ganon inside it until it is removed.

The Bound Chest has similar properties to Pandora's Box, a Greek myth.
