The Wall, protecting Insomnia.

The magical barrier known as the Wall has long kept the empire at bay, and thereby maintained the peace, yet not entirely without struggle. Sustaining the Wall imposes an immense physical burden upon the king, but to let it fall for even a moment would be to invite total annihilation.

The Magic of the Lucii - III

The Wall (魔法障壁, Mahō shōheki?, lit. Magic barrier) is a transparent magic barrier that surrounds the city of Insomnia in the Final Fantasy XV Universe. Erected 150 years before the events of Final Fantasy XV, it protects the Crystal within from outsiders and is maintained by the ruler of Lucis, who uses the Ring of the Lucii to channel the Crystal's power to manifest the Wall. Upholding the Wall drains this ruler's life-force. As shown in Final Fantasy XV: Episode Ardyn, the Wall generation is augmented by various amplifiers positioned around the city.

The Crystal projecting the Wall from the Citadel.

According to documents produced circa the advent of the Kingdom of Lucis, metal procured from adamantoise shell was used in the construction of conduits used to channel the Crystal's power into the Wall around the Crown City.

Over 150 years ago Niflheim Empire declared war on Lucis and Accordo. Accordo was annexed, and the king of Lucis erected a magic barrier to protect his country and take up a siege position. Originally the barrier covered large portions of the continent, but thirty years ago in the culmination of the Great War, King Regis's father, Mors Lucis Caelum, consolidated the power of the barrier over Insomnia—strengthening it—to protect it from the empire's newly developed magitek soldiers.[note 1] Insomnia thus became isolated from the rest of Lucis, and Niflheim began to make further inroads into Leide, Duscae and Cleigne regions. In M.E. 734 Niflheim conspires to bring the Wall down by having the Adagium destroy the Wall amplifiers, but the plan fails.

On the day a peace treaty is to be signed between Lucis and Niflheim, magitek infantrymen breach the Wall and infiltrate the Crystal Chamber. They bring the Wall down, and Niflheim airships invade the Crown City. The absence of the Wall allows daemons to spawn in Insomnia, plunging it into chaos.

Kingsglaive use magic to project walls.

King Regis and the Kingsglaive use protect magic to erect magical walls to shield themselves and those with them, which is similar to the Wall but in a much smaller scale. After Regis dies, the Kingsglaive members lose the ability to use magic, but Nyx Ulric again projects a barrier to protect Lunafreya Nox Fleuret when he gains the power of the Ring of the Lucii.

Niflheim invades Insomnia and Prince Noctis embarks on a journey to reclaim the throne of Lucis. While infiltrating the imperial magitek laboratory Zegnautus Keep, he learns the empire has been developing a device that could disable the Wall, as well as the Lucian royalty's and Kingsglaive's magic, called the Wallbreaker Wave. A version of this device seals Noctis's powers while within the area.

Ardyn's Wall covers the Citadel.

In the Windows and Royal Editions, Ardyn Izunia erects a magical barrier around the Citadel when Noctis returns to Insomnia, implying he crafted it to torment Noctis. It resembles the Wall that Regis used to project and the shield magic Kingsglaive use, but with a red hue rather than blue.

Behind the scenes[]

The Wall is similar to the palings seen in Final Fantasy XII. The term is the same for both in Japanese. Likewise, the Wallbreaker Wave is similar to the crystal jammer from Final Fantasy Type-0, used by Milites to disable the magic used by the Dominion of Rubrum to defend their capital.



  1. Takka's dossier says that "King Regis scaled back the Wall", but this seems to be a mistake, as Regis didn't ascend until after the Great War.
