Cid Pollendina: Oh, shut up and help me remodel the Subterrane page!
Please expand this article into a full one. The following tasks need to be completed:
  • specify the Subterrane's sections and its enemy formations in the iOS/Android versions.

This request can be discussed on the associated discussion page. Remove this notice upon completion.

The Subterrane of the True Moon is the area preceding the final dungeon of Final Fantasy IV: The After Years, the Depths. The first seven floors directly mirror the Lunar Subterrane from Final Fantasy IV, but every floor after is new. Bosses from Final Fantasy IV appear to attack the party, such as the CPU or the Magus Sisters, and eventually the Archfiends.

On B12 in the Subterrane, the party has to fight Leviathan and Asura to break the seal leading to last floor, where the Dark Knight will fight them. Clearing the Subterrane will allow access to the Depths and the interdimensional elevator, which can also take them to the tail collector's house.

At each save point the player encounters, they will be allowed to rest and heal their party without needing a Tent or Cottage the first time. If the player has imported their data from previous tales and has the proper characters available, they may witness a scene during the rest. These scenes can result in new Band abilities being learned. The player does not need a specific party to view these scenes or learn these Bands, as long as the characters involved were imported they will be seen. When encountering Rubicante, if Edge is in the party, he player will have the option to duel the Archfiend one-on-one, receiving a Fire Scarf for the feat. The item will not be received if the player fights Rubicante with their full party, with or without Edge in it.

If Rydia is in the party when fighting Asura and Leviathan, they will return to her as summons after being defeated, otherwise they will be lost. Against the Dark Knight, Cecil and Golbez must be in the active party or else the Dark Knight will instantly kill the party when the battle begins. If only Cecil and Golbez are present, after the battle Golbez will die and not be available for play for the rest of the game. If Ceodore and Rosa are also in the party, Golbez will survive.

During certain moon phases and in specific areas, the player can encounter enemies that drop colored tails that can be traded to the tail collector for rare and powerful equipment. The enemies that drop the tails can also be encountered in groups with other enemies in the same areas, but have lower stats and do not drop the tails when in a group.

The Subterrane in the 3D version is different from the other versions.
