The Mirror of Twilight was created by the Golden Goddesses — Din, Nayru, and Farore — to banish the Interlopers to the Twilight Realm. It serves as a link between the Twilight Realm and Hyrule, allowing beings to travel between the two worlds as desired. It is housed at the top of the Arbiter’s Grounds, where it was used in past ages to banish criminals convicted of crimes against Hyrule or the Royal Family to the Twilight Realm.
