The Keep of Forgotten Time is a location on Final Fantasy XII: Revenant Wings which houses the Eternal. It is protected by strong aegyl warriors, which are in truth, the anima of those same warriors, kept alive by Mist for eternity. It is later revealed as the gate to Feolthanos' true home.

Mission 79: Wings of MidnightEdit
- "The massive creatures Tomaj saw in the keep are powerful scions of old. They are led by a great black wyrm the party has encountered once before."
The mission starts off the with Titan in the middle of the map. After he is slain, Ramuh will appear to the northwest. This pattern is repeated with Shiva appearing in the east after Ramuh's defeat, and Ifrit to the northeast after Shiva's defeat. Once the Lord of Flame has fallen, Bahamut will finally descend upon the battlefield, and only his defeat will complete the mission and unlock him on the Ring of Pacts.
