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 Infernal Castle (煌魔城(こうまじょう)), also known as the Vermillion Apocalypse's Castle ((あか)魔王(まおう)(しろ)) and Blaze Demon Castle in Falcom's romanisation, is a castle in Heimdallr. It is usually located beneath the Valflame Palace.

Members of the Hexen Clan can summon the castle through the incantation Lucifen Lied, after which the stage will be used for the Infernal Rite. It offers a stage for the ultimate clash between Divine Knights that have been awakened in preparation for the Rite.

The subterranean castle, approximately 800 arge in height, is pushed toward the surface level by the purgatory's great tree (煉獄(れんごく)大樹(たいじゅ)). Its roots can be seen surrounding the castle. It is also responsible for spawning high-level spirits in the second stratum of the castle.


As chronicled in the Black Records, the Infernal Castle appeared during the War of the Lions on 1 July, S.952. It was sealed three days later, on 4 July S.952, by Dreichels Reise Arnor and Lianne Sandlot.

During Trails of Cold Steel II, it was summoned again by Vita Clotilde on 31 December, S.1204, only to disappear again later that day.


The castle's layout and contents change depending on both who summons it and what circumstances they summon it in; the iteration seen at the end of the Erebonian Civil War differs from the War of the Lions version. The former consists of multiple sections, indicated as:

  • Stratum 1
  • Stratum 2, at ca. 100 arge height
  • Stratum 3, which is said to be the place where light and dark are always at odds with one another
  • Highest Stratum
  • Vermillion Throne, where the Infernal Rite takes place

The areas are riddled with high-level spirits from the Dark Ages and, in the case of the Erebonian Civil War iteration, archaisms brought in by Ouroboros.

At the end of each stratum you fight a boss:

  • Duvalie and Bleublanc are fought in Stratum 1
  • Xeno and Leonidas are fought in Stratum 2
  • McBurn is fought alone in Stratum 3
  • Vita and Crow (and later the Vermillion Apocalypse) fought in the Vermillion Throne

Note: Rufus Albarea and Altina Orion are never refought in this dungeon, possibly because they are planning to betray the Noble Alliance.

  • The Infernal Castle's Highest Stratum originally featured two additional floors, which were removed from the final version of the game.
