Moon server

The  (月サーバー) is the hidden fourteenth server. Before the Catastrophe, it was the test server and was referred to as "N_VOEN". People speculated that the server would be used for player content in the future, which turned out to be true in the Homesteading the Noosphere expansion pack&mdash;at least, it would have been, had the Catastrophe not occurred.

Overview
During the game era, this server was called "N_VOEN" and was a testing server before expansions were rolled out. Shiroe created his Roe2 alt on this server some time prior to joining the Debauchery Tea Party. Whenever a new expansion is about to be released, N_VOEN is closed off starting around a week before the release.

The Catastrophe
The Ancients, after receiving a premonition of a dangerous foe housed on the Moon (the Genius), gather together to stop them. While preparing to invade the Prison of Time, one of its dungeons, they are ambushed by the Genius&mdash;or rather, the Genius-Travelers inhabiting their bodies&mdash;and quickly find themselves overwhelmed.

Elias Hackblade, in an attempt to salvage their forces, leads a suicide group to delay the Genius while their allies drew all the mana from Theldesia's Intercity Transport Gates to power up their transport gate and attack the Prison of Time. This occurs right around the same time as the Catastrophe, causing Adventurers to find that the transport gates are no longer functional upon awakening in this world.

After the Catastrophe
After dying, Adventurers are taken to Mare Tranquillitatis on the Moon server, where they sacrifice Empathiom to revive.

Krusty, after the incident with Takayama Misa's Calamity Hurts at Seven Falls, awakens before the Genius Bucaphi in Mount Kunlun, one of the floors in the Prison of Time. His memory of this encounter is sealed away when he refuses to accept her power and is thrown into the Zhongyuan server.

Locations

 * Mare Nectaris - An area mentioned in A Sunday in Akiba. (Officially translated as "Sea of Soma," which is a literal reading of its kanji.)
 * Mare Tranquillitatis - A dungeon on the Moon Server. Adventurers who are killed eventually end up here before sacrificing some Empathiom to revive.
 * Pilgrim's Citadel - Originally a separate location, it has now been absorbed into the Prison of Time.
 * Prison of Time - A twelve-floor dungeon that now houses the Genius. The currently-known floors, in unknown order, are:
 * Mount Kunlun - The area where Bucaphi resides.
 * Corridor of Confusion
 * The Sacred Wine Palace
 * The Bamboo Field
 * Rampart of Needle Tower
 * Sky Labyrinth of Imbrium - An area mentioned in A Sunday in Akiba. (Possibly a dungeon that houses Mare Nectaris and Mare Tranquillitatis.)
