Moon Culvert

The Moon Culvert (ムーンカルバート) is one of the lower areas of the Second Tower of Ar tonelico, located far below Pastalia. It consists of several walkways and lifts placed above a large hole, whose purpose seems to be unknown. There are several rumors of this place being the location of a hidden treasure, but very few people have actually come in search for it.

Prior to the Ar tonelico II Events
The Moon Culvert is in fact one of the multiple redesigns the Second Tower suffered when the AHPP abandoned their support for Tyria and the Third Tower of Ar tonelico project. This hole was made as an alternative shooting point for the XP Shell, and Frelia would perform the tasks that Tyria was supposed to carry out. However, due to the Grathnode Inferia, these plans were never realized, and the Moon Culvert stayed as a great hole because there was no time to add the mechanisms and rails that would be used for the shooting of the Shell.

Several years later, Infel, having discovered that it wouldn't be possible to bring back Nenesha to life after some time researching the Heart of the Land into which her soul was sublimated after their combined Metafalica failed and Raki killed her, decided to store the Heart in this place to keep it away from curious eyes until the day in which Hibernation would be executed. However, the information was somehow leaked, but got twisted in the process, making everyone think it was some kind of rare jewel or incredible treasure.

Some years prior to the game, Leglius Branchesca's daughter, Alicia, went to this place enticed by the rumors of the treasure. Leglius and his wife came after her, knowing the Moon Culvert was a very dangerous place. However, after they had found Alicia, the ran into a berserk IPD, who killed both Alicia and Leglius' wife. This event left a great scar on his heart, which made him continue following blindly the orders his boss, Alfman, issued him.

Layout
The Moon Culvert has all the conditions to be a very annoying dungeons: several floors interconnected by lifts, a high encounter rate and several treasure chests hidden in an optional path which the player may end skipping by accident if they take the other path. However, the encounter rate and number is thankfully low, although the enemies have gotten stronger once again here. Therefore, it's advisable to be careful in battle, as the first time coming here starts a gauntlet of sorts through two other dungeons.

Additionally, it isn't really possible to completely explore the area on the first or second visits, as the first time around the lifts leading to the lowermost level aren't operational, while the final room kicks the player out of the Culvert upon defeating the boss here for story reasons, so it will be necessary to visit it at least three times in order to find everything this area hides. Similarly, the enemy rosters change after Phase 3 has finished, so the second visit will have much stronger foes awaiting for the player.
