Lunar Subterrane

The Lunar Subterrane is the final dungeon in Final Fantasy IV. It's a massive cave complex, filled with strong monsters. It can only be accessed from Crystal Palace once the Giant of Babil has been destroyed.

The caverns contain a great deal of hidden passages and strong monsters, including dragons. As the final dungeon, the strongest equipment pieces in the game exist here (for the original Super NES release at least). It is also inhabited by many monsters, especially several types of dragons. There are also many monsters hidden in treasure chests, and at the bottom of the cavern lay several sealed relics guarded by minions of Zemus. Eventually, the caverns leads to the Lunar Core.
