Hold on, it looks like Millium wants to tell you something.
Hey-hey! White Rabbit here! Lammy scanned this article and said it contains unmarked spoilers for all Trails games. Turn back now if you don't want to get lasered! Okay, byee!

The Reverie Corridor (夢幻回廊) is an instance of Phase Space located on the ground floor of the Old Schoolhouse of Thors Military Academy, Heimdallr, used as part of the 'Land of Trials' system devised by the Gnomes of Erebonia.


The Reverie Corridor is one of several phase spaces accessed in Zemuria. It was created by the Gnomes and reputedly utilises some of their finest technology, such as the creation of a large-scale phase spaces, the expansion of flexible materials and the development of the Awakener's trial system.[1] The Reverie Corridor that appears below the Old Schoolhouse itself, however, is not an official trial and is the result of a disturbance triggered by the action of a different trial.[1]

Trails of Cold Steel II

Following Rean's return to Trista to complete his education at Thors, on the final night before the departure of the rest of his graduating class, the Old Schoolhouse suddenly shines in a similar fashion to how it did upon the activation of Valimar's trial. Rean, and a host of his gathered companions decide to investigate the strange occurrence as part of their final mission as a class. Upon entry to the phase space, Valimar notes its peculiarities and links to the Gnomes.

After completing the series of corridors, each themed after one of the lower elements and defeating several Cryptids, Class VII and company confront Loa Luciferia, a being similar to one they fought in the Realm of the Great Shadow, only this time , it is blazingly bright. The being tells them it is but a 'shadow' trail and grants no reward, a trail that never should have existed but Class VII state that overcoming the challenge is reward enough.


At the end of Trails of Cold Steel II, Epilogue: "Winter's End", the interior of the old schoolhouse transforms into the Reverie Corridor. The area has no fixed structure and changes its layout completely every time the players enters the dungeon from outside. Every time, monsters will revive and treasure chests are reset, allowing players to conquer it as many times as desired. The party can reorganised by talking to any of the team members at the base of the corridor. After reaching certain points, it will become possible to warp back to the base area.[1]

All Class VII members and supporters can temporarily use Overdrive no matter who they are linked with. The amount of link EXP gained in battles has also been increased to three times its usual amount. The enemies in this area are significantly stronger than those in the final chapter and must be approached with due caution. The specifics of enemies fought will be recorded in the "EX: Reverie Corridor" section in the notebook.[1]

It is possible to purchase Phantasmal Mirrors at the base of the dungeon. Characters can equip different mirrors which in turn transform the said Class VII member into one of five otherwise unplayable characters: Altina Orion, Crow Armbrust, Vita Clotilde, Lloyd Bannings or Rixia Mao. They will also receive the new character's Quartz set, replacing the original Class VII fighter. However, these forms can only be used in this dungeon. Each of the 5 mirrors cost 200k each.


  • During development the Reverie Corridor was referred to as the Infinity Labyrinth (無限迷宮) or Reverie Labyrinth (夢幻迷宮). The game's debug mode lists the Infinity Labyrinth under "Special", which would take place after "Crossbell/Epilogue". For more information and screenshots, see the entry on TCRF.
  • The revelations in Trails into Reverie describe 'reverie corridors' as examples of phase spaces created for a specific purpose. AZOTH mentions the 'Land of Trials' system devised by the gnomes to test their awakeners specifically. The name 'Reverie Corridor' may not be exclusive to this one location, but rather may be a catch all term for phase spaces that involve trials as a whole.
