Hordes of daemons depicted at the bottom of a painting.

Eos is plagued by hordes of daemons, vicious nocturnal creatures of various forms that strike fear into the hearts of even the most seasoned hunters. Daemons are denizens of the night, and the more predatory among them are drawn to the roads after dark. People now dread the setting of the sun for fear of what monsters might be lurking in the shadows. In recent years, the daemons have grown in number while the nights have grown longer. The correlation between the two phenomena is yet unproven, but scientists persist in their search for a link.
—Daemons of the Night at the tutorial

Daemons (シガイ, Shigai?, lit. Corpse) are nocturnal monsters that plague the world of Eos in the Final Fantasy XV Universe. They are humans and animals parasitized by the Starscourge and have started to appear in greater numbers. The Wall maintained by King Regis prevents daemons from spawning in Insomnia. Niflheim employs daemons in its military.

Daemons resemble recurring enemies in the Final Fantasy series. Their otherworldly appearances contrast the more realistic monsters encountered in the daytime.


Daemons are beings that thrive in the dark, and are damaged by light. They lurk in old ruins and caves, and emerge out in the open at night. If they are out when the sun rises, black mist begins to emit from their bodies as they take damage from sunlight. Daemons are thus also repelled by the bright lights of inhabited areas, and even the strongest headlights of cars. The kings of Lucis are best equipped to battle daemons, as their Royal Arms contain the power of light. The Crystal is believed to have the power to repel daemons.

Spoiler warning: Plot and/or ending details follow. (Skip section)

Recently turned daemons retain some of their former selves. Iedolas Aldercapt, who had sought the Ring of the Lucii, still focuses on obtaining it from Noctis when he becomes the daemon Foras. Ravus Nox Fleuret, meanwhile, begs Noctis and his friends to destroy him, unable to control his actions. Throughout the battle with Noctis and his friends, Ravus curses Ardyn for turning him into a daemon.

Noctis VS Marilith

Noctis fights Marilith.

As a child, Noctis Lucis Caelum was attacked by a Marilith. The daemon killed the woman protecting Noctis, and was fended off by King Regis.

Now an adult, Noctis heads to Altissia with his friends Ignis Scientia, Gladiolus Amicitia and Prompto Argentum. They are attacked by Niflheim while on the road, and an imperial airship releases the same Marilith that injured Noctis long ago upon them. Enraged, Noctis engages the daemon and destroys it.

Kingsglaive: Final Fantasy XVEdit


Diamond Weapon.

The combined forces of Niflheim and Tenebrae use a variety of daemons to breach the borders of Lucis. Among them is Diamond Weapon, which forces the opposing Kingsglaive to retreat.

During the fall of Insomnia, Niflheim deploys several Diamond Weapons to ravage the Crown City.

Final Fantasy XVEdit


A Grim Reaper-type daemon.

All daemons were once normal creatures until the outbreak of a parasite introduced that began mutating organisms into monsters. The ancient civilization of Solheim is implied to have fallen to daemons, as legends tell that 2000 years ago mankind was being eroded by a plague, and till present day daemons still lurk in old Solheimian ruins. The plague subsided by the hand of the first Lucian king, and the following centuries of peace led to the formation of four new nations.[1]

The Empire of Niflheim, ruled by the Aldercapt family, seeks to become the new Solheim, and attempts to recreate its lost technologies and conquer the world. In M.E. 501, the imperial army discovered a life form previously unknown to them: daemons.[1] Although not directly stated, it is possible Niflheim discovered daemons from old Solheimian ruins. It is implied that Niflheim's experiments with these "new" life forms brought Starscourge back in a large scale, and inadvertently infected their own people with the plague.


A magitek soldier in Kingsglaive: Final Fantasy XV.

Imperial research has shown that on the cellular level, daemonic cells disintegrate when exposed to light, but this can be countered via modern armor. These soldiers make up the imperial magitek infantry, who start out as human babies who are changed through various procedures.

The Empire's use of daemonic energy spirals out of control, with daemons overrunning the Zegnautus Keep, the imperial magitek laboratory. Daemons slaughter civilians in the capital city of Gralea, while a "vanishing disease" that at first is not understood to be Starscourge, sweeps the imperial lands turning its citizens into daemons the Empire cannot control. West Gralea had to be quarantined to prevent the parasite from spreading as more people kept disappearing. The city is ultimately taken over by the daemons, including its high ranking imperials, such as Ravus Nox Fleuret and the Emperor himself. Every time a human becomes a demon, their clothes are left behind, such as the many uniforms and the Emperor's robes in the Keep.


Ravus as a daemon.

Prince Noctis embarks on a journey to reclaim his throne after the Crown City of Insomnia is destroyed by Niflheim that steals Insomnia's Crystal. After the Oracle, Lunafreya Nox Fleuret, dies, Starscourge begins to overwhelm the world even more rapidly, as she was the only person in the world with the power to heal people from Starscourge. Noctis's mission shifts from reclaiming Lucis to saving the world from daemons, and he believes he can do so by the light of the Crystal. When he finds the Crystal from Zegnautus Keep however, he is absorbed inside it and learns of his calling as the True King from the astral god Bahamut. The True King is the king spoken of in prophecy who will arrive when the world is veiled in darkness to bring back the light.

Noctis disappears for ten years during which time the sun never rises again and daemons take over the world. Civilization collapses as daemons run amok and most people who don't migrate to the town of Lestallum, mankind's final stronghold, are killed. When Noctis returns he finds a world teeming with daemons with previously inhabited areas like Galdin Quay abandoned.


A daemonic Ardyn Izunia.

Noctis reunites with his friends and heads to the ruins of Insomnia to kill Ardyn Izunia, his immortal ancestor whose soul had been corrupted by daemons. 2000 years ago, Ardyn was a member of the Lucis Caelum bloodline who fought daemons by absorbing them into himself, but this corrupted him and made him something akin to a daemon himself. Unable to enter the afterlife with his corrupted soul, Ardyn has plotted for millennia against the Crystal that had rejected him and the Lucis Caelum bloodline that had continued to reign without him. Ardyn has become the embodiment of daemonic energy in the world, but when Noctis sacrifices his own life to erase Ardyn's soul, Eos is cleansed of the Starscourge. The daemons disappear as the sun rises.

Spoilers end here.



An Iron Giant taking damage from sunlight.

Daemons are encountered on the field at night and in caves during any time of the day. If Noctis and his friends come upon them while driving the Regalia, they will stop the car and get out to fight. Daemons are fiercer and stronger than the creatures that appear during the day. They will not disappear if the player is in a battle with one even if day breaks. If facing a powerful daemon for a hunt, it is advised to wait until 3 AM to start the fight, as once day breaks, the player simply needs to drag out the battle and the daemon will continuously lose HP from sunlight. With the Starshell, Prompto can weaken daemons by lighting up the surrounding landscape with a series of flares.

When Ignis can drive the Regalia at night, the player can open the main menu while the Regalia is on auto-pilot to prevent daemons from spawning.

Their attacks not only drain a character of their HP, but also reduces their maximum HP without putting them into the dying status. As such, one should keep the warp button pressed at all times when facing powerful daemons and should finish them off quickly as soon as possible.

Other appearancesEdit


Noctis chases after Lunafreya Nox Fleuret's white dog Pryna through various dreamscapes until he loses his magic powers and becomes surrounded by Cerberus beasts on a fiery plain. A demonic Noctis appears to kill Luna and the dog he was following turns black and scorched.

Cerberus is a three-headed dog that guards the underworld's gates in Greek mythology. It appears as a daemon in Kingsglaive: Final Fantasy XV and Omen, but doesn't make an appearance in Final Fantasy XV.


Dæmons are benevolent spirits that exist in classical mythology. They are of the same nature as mortals and deities. In Final Fantasy XV, they appear more like demons. A demon is "an evil spirit or devil, especially one thought to possess a person or act as a tormentor in hell."
