LAN Castle - Depths is a dungeon unlocked once the player starts chapter 7. It, for some reason is named LAN Castle - Depths despite having LAN Castle already with its own "LAN Castle - Depths". This dungeon contains one part, LAN Castle - Underground.


The following items can be found in the dungeon. Items in the treasure chest can only be obtained once. Numbers are marked on the map.

Note 1: Stars on the map are hidden item locations. They will spawn in one of the locations and can be found through Treasure Search. They can be picked up once every time you enter the dungeon. To find more hidden items, you need to re-enter the dungeon.
Note 2: The number beside the treasure items on the table indicate the point on the map where they can be obtained.

Chapter 7: Fetal Contraction

The party search for Uranus, the ancient CPU that "defeated" the Deity of Sin. They find her by making a ruckus and ask her how to defeat the Diety of Sin Arfoire. She explains that she and three other dead CPUs could only seal her. The party knows to seal the Diety of Sin they must have damaged her. She explains that the Diety of Sin exists as an amalgamation of all negative emotions and desires. If the party desires something else opposite to that, the Deity of Sin will be defeated. Nepgear decides that their desire to save Gamindustri is what will defeat the Diety of Sin. The party thanks Uranus.

Apocalypse: A Savior's Sorrow

The party follow an old man's advice to seek the cursed sword which will slay the Diety of Sin. They find a rusted sword to which they are disappointed with. Nepgear decides to keep it anyways.
