Depths

The Depths of the True Moon is the final dungeon of Final Fantasy IV: The After Years. It consists of 29 floors, and the party will fight bosses from the original Final Fantasy to Final Fantasy VI. The Creator summons them from Crystals (the Creator did not necessarily destroy the worlds they are from).

Despite that the Depths are in an orbiting moon, the Depths bear a resemblance to the Ronka Ruins from Final Fantasy V, in that it looks like ancient ruins with plants and high technology. This is due to the fact that the Creator's moon is the remains of a space fleet that his race piloted. There are also crystals emerging from the floors of the Depths, and broken shards scattered on some.

The last floors of the Depths is where the Maenads are fought, including Bahamut. Like in the Subterrane, there are save points on some floors where the player can choose to rest to initiate a cutscene between two characters, and learn a band ability such as Spiral Blow.

Trivia

 * It is interesting to note that the color of the crystals and chests on their respective floors match the same color used for the logos from the games the bosses originally appeared in. For example, the floor with Final Fantasy V's bosses uses purple, while Final Fantasy VI's uses red.
