Otherworldly deities' playground for the all-knowing. One cannot help but feel despair within its confines.

The Seraphic Gate is an optional dungeon featured in all Valkyrie Profile titles, and is accessible after saving at the last save point in the game and reloading. In Valkyrie Profile, this means finishing the game first, as it is not possible to leave the final dungeon. In Valkyrie Profile 2: Silmeria, it is possible to complete the Seraphic Gate before facing the final boss. In Valkyrie Profile: Covenant of the Plume, it is necessary to obtain all three endings in order for the dungeon to become available.

The Seraphic Gate shares some common characteristics across all three games:

The dungeon has no relation to the actual storyline of the game: it thus contains humorous references which either mock a certain aspect of it or break the fourth wall.
The dungeon is very large, divided into multiple floors with only one save point at the very beginning, thus requiring lengthy backtracking when nearing the end.
The dungeon contains very valuable treasures, but also very powerful enemies and bosses, the latter often being stronger than the final boss itself.
The dungeon allows the player to recruit characters which were either not available during the main game (non-playable characters or villains) or have left the party. This can lead to aberrations such as both Brahms and Dylan or Hrist and Leone being present in the party at the same time.
Gabriel Celeste and the Ethereal Queen always feature as bosses.
Hamsters always feature as random enemies.
The dungeon can be completed up to ten times in order to obtain the Angel Slayer.
