Arbiter's grounds was originally a prison before it fell into ruin. It was used as a prison for only Hyrule's worst criminals, before they were sentenced to execution or life time imprisonment in the Twilight Realm. The mirror of twilight and chamber of the sages were located at the top of this prison.
By the time of the events of Twilight Princess, all that is left of the once mighty prison are empty ruins. One of the last known prisoners at the grounds was Ganondorf. However, when the sages tried to execute him, the Triforce of Power prevented his death and they trapped him in the mirror of twilight.
