Final Fantasy Wiki

The spirits of past kings of Lucis.

There once lived a man, born to a mortal but blessed with powers divine. Conjuring a collection of glaives he dispelled the darkness plaguing our star. As a reward for his efforts, the gods granted him a holy Stone—the Crystal, which he was to guard at all costs, for it would one day choose a King to see us through the coming disaster and lead us to salvation.

Cosmogony chapter "The Crystal"

The kings of Lucis, also known as the rulers of yore, form the Lucis Caelum bloodline that wields the Crystal's powers by birthright in the Final Fantasy XV Universe. They are the monarchs of the kingdom of Lucis. According to legend, the Crystal is of divine origin and was bestowed to humanity alongside the Ring of the Lucii, which harnesses the Crystal's power for a chosen few.[1]

The kings' spirits are referred to as the Lucii (pronounced: lucy-eye) in Kingsglaive: Final Fantasy XV, but the past kings are not called Lucii out loud in Final Fantasy XV, only in written form in the lore tutorial "The Magic of the Lucii", some of the Archives entries, and in the Legacy of the Lucii Armiger Unleashed Technique. Rather, the Lucii are being referred to simply as "the kings of Lucis" or "rulers of yore." Despite being referred to as the kings of Lucis, there have been queens, such as the Rogue. The first king is said to have reigned some 2000 years ago. Regis is the 113th king, meaning that on average, the reign of each monarch lasted less than 18 years.

Three of the monarchs are included as new boss battles in the PC and Royal Editions.


The Crystal is the divine cornerstone of the Kingdom of Lucis. The Stone has a will of its own, and channels its sacred power through the Ring of the Lucii to the monarch who bears it. Monarchs in the line of Lucis have the innate ability to conjure magical weapons. A handful of close attendants are also afforded access to this selfsame power. 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 destruction.

"The Magic of the Lucii" lore tutorial from Final Fantasy XV

When a monarch of Lucis dies, their spirit is taken by the Ring of the Lucii. The one who wears the ring can communicate with the spirits of the past kings and queens, known as the Lucii, whose spirits reside in the ring. The Lucii don suits of dark armor that never show their face. Though each suit is unique, they resemble Bahamut, who presents himself similarly.

The kings can extend their powers outside of the Lucis Caelum lineage at the monarch's behest, as shown in Kingsglaive: Final Fantasy XV where the Kingsglaive wield some of King Regis's magic, and in Final Fantasy XV where Prince Noctis's friends share in some of his powers, such as forging weapons from thin air and using magical potions and Elemancy. During Noctis and his friends' travels, potions and elixirs gain their healing power from him[2]—without Noctis, they would be just regular soda. In Final Fantasy XV: Comrades, the Glaives can use some of the Lucian kings' powers via Royal Sigils said to be protective relics of past monarchs.

Prince Noctis inherits a royal arm; the "soul fragments" symbolize the bonding of the Lucian kings' souls.

The kings are entombed across Eos in hidden royal tombs, and leave behind weapons of their legacy known as royal arms to empower their descendants, namely, the True King. Only those of the Lucian lineage can brandish the royal arms, which glow when grasped by their rightful wielders. Using the royal arms drains the wielder's health, but they are especially good against beings of the dark.

The Lucian bloodline has a special power to brandish their inherited royal arms all at once, known as Armiger, although this state can't usually be sustained for long. The weapons will materialize as crystalline silhouettes that circle the king who can rapidly attack their opponent with a new weapon each hit. According to the Final Fantasy XV Ultimania, unleashing the combined power of kings (Armiger) and the Crystal can eradicate the Starscourge[3], the plague upon the planet of Eos. The members of this bloodline can teleport, a skill used for both offense and defense in the form of warping and phasing through enemies' attacks, use various types of magic, project magical barriers as shields, and summon weapons from thin air to the grasp of their hand.

The gods are said to have blessed the Lucis Caelum bloodline, the Scenario Ultimania positing that the Astrals "blessed the King and the Oracle with their powers"[3] but the specifics of the magic the gods gave them is ambiguous. "The Crystal" chapter in Cosmogony says the Founder King was born a mortal but "blessed with powers divine". According to Final Fantasy XV: Episode Ardyn – Prologue, the nobles of House Caelums used their "god-given powers" to purge the scourge from the land, and thus earned the masses' trust. According to the lore tutorial, the monarchs in the line of Lucis have the innate ability to conjure magical weapons, and Noctis's dossier describes his magic as "innate power". Final Fantasy XV -The Dawn of the Future- specifies that the Lucis Caelums' ability to conjure weapons from thin air is a power gifted to them by the Astrals.[4]

The kings of Lucis combine their powers.

The Crystal is a magical stone of divine origin that is a source of immense power whose light is said to be for the benefit of all of mankind. The Final Fantasy XV Scenario Ultimania posits that rather than being able to use the Crystal's true power, the kings of Lucis have the responsibility of protecting it, and that the Crystal picks the "Chosen King" when disaster comes to the world.[2]

For the last 150 years, the king who protects the Crystal has shielded it from outsiders by maintaining the Wall, a magical barrier that isolates Lucis from the rest of the world. Upholding the Wall drains the king's life-force, accelerating their aging. Having conquered all other lands, bar Lucis behind its magic barrier, Niflheim Empire reigns supreme, only repelled by those who derive their power from the Crystal.

The Old Wall is a series of towering statues strewn throughout the Crown City of Insomnia. Honoring the ancient kings of Lucis, who dwell within the Ring of the Lucii, it activates when the city is in danger at the behest of the current monarch if they are strong enough, or one deemed worthy by the kings of old. According to the Final Fantasy XV Scenario Ultimania, the statues were created 2,000 years ago to serve as coffins to each hold the soul of a dead monarch. From these coffins, the monarchs would await the coming of the "Chosen King." The statues were also intended to serve as the Wall that protects the kingdom of Lucis.[5]


The Accursed[]

The man who was to become the first king of Lucis was rejected by the Crystal before his ascension to the throne for the darkness that had come to inhabit him. He was cast aside and the Crystal would choose another in his stead.

Somnus, the Mystic[]

The Mystic.

The Founder King lived 2000 years ago and is the younger brother of The Immortal Accursed. He was served by Gilgamesh as his sworn shield; Shield of the King would become a title given to the Lucian monarch's main bodyguard. The Founder King is said to have risen to protect the first Oracle, and is known to have wielded a longsword. Out of all the royal arms, Noctis displays a preference for the Blade of the Mystic, as he wields it the most out of all battle features in which he wields a royal arm.

The Mystic fought the Starscourge 2000 years ago, and founded the nation of Lucis. He is the most prominent king in Kingsglaive: Final Fantasy XV. He talks to Nyx Ulric and is the last king standing at the battle's end. His statue depicts him with sleek armor, a waist cape, and horns protruding from his shoulders and helmet. In Final Fantasy XV: Comrades, the Mystic's Sigil: Graviton, allows the bearer to create a powerful gravitational force that draws enemies close, while limiting their abilities. The Mystic has an extended role in the Windows and Royal Editions of Final Fantasy XV: he appears as a boss in the final dungeon, and has a monument in Keycatrich. After acquiring all thirteen royal arms, interacting with the statue yields the Founder King's Sigil that lets Noctis use Armiger Unleashed. He also acts as the final boss for Final Fantasy XV: Episode Ardyn.

The Wise[]

The Wise.

Believed to be the first king who raised the Wall of the Lucian Kingdom, he is known to have wielded a simple sword. His statue and spirit in the Ring of the Lucii are thinly armored with multiple wings.

In Final Fantasy XV: Comrades, the Wise's Sigil: Dragoon Drain, allows the bearer to perform a leap jump attack, its animation being similar to Aranea's Dragoon Dive. The Sigil also allows the bearer to replace their curative spells with HP and MP lancet-draining attacks, making the Wise a Dragoon archetype despite his royal arm not being a spear.

The Royal and Windows Editions have monuments dedicated to a some of the rulers of yore, which are signed by "Optimus Lucis Caelum," the 108th Lucian king. Noctis being the 114th king by the typical lengths of a generation would suggest that this king may have been the Wise.

The Conqueror[]

The Conqueror.

A king said to have lived in times of chaos, who rose as a champion that united the Lucian continent and fought for his people, allowing them to usher in a great age of prosperity. He is known to have wielded a halberd. The Conqueror's statue and Lucii form has thin armor, with a waist cape, and long, thin capes hanging from his elbows, with his helmet having a long, hair-like tassel on the top.

In Final Fantasy XV Comrades, the Conqueror's Sigil: Elemancy, allows the bearer to temporarily imbue the surrounding area with elemental properties with an elementally-aligned weapon.

The Clever[]

The Clever.

A king said to be well versed in the arts, be it the physical, the intellectual, martial, or that of skill. He is known to have wielded a crossbow. His statue and Lucii form has thin armor with several lengths of a segmented cape draped over his back, and antler-like extensions on his helmet.

In Final Fantasy XV Comrades, the Clever's Sigil: Spectral Arms, allows the bearer to conjure an arsenal of eight special armaments and wield them while replacing their offensive spells.

The Wanderer[]

The Wanderer.

A king who found no boundary to the land and wandered the world, going where no man had gone before. He is known to have wielded twin swords that could combine into an enormous besieging weapon. The Wanderer's statue and Lucii form depict him with bulky, segmented suit of armor, a monocle-like object on his left eye, and, curiously, four arms with circular joints, suggesting the statue can rotate his arms at these points.

In Final Fantasy XV: Comrades, the Wanderer's Sigil: Cheer, enables the bearer to empower their comrades with five status enhancements.

The Oracle[]

The Oracle.

Though the Oracles are known as the royalty of Tenebrae, one of the royal arms is the Trident of the Oracle, and one of the twelve statues of the Old Wall in Insomnia is the Oracle King who wields a giant version of the trident in the battle against the Diamond Weapons. As told in the monoliths in Steyliff Grove Menace, this king likely watched the Oracle of his time perish before his eyes, and thus took up her trident. Due to her not having a successor yet, the Oracle King held a temporary status as both a king of Lucis and Oracle of Eos. In Kingsglaive: Final Fantasy XV Nyx and Glauca end up fighting on the Oracle's shoulder, but the statue tosses the trident and warps away and Nyx and Glauca fall. The horn at the front of his helmet resembles a bird. The statue has a broad chest, long cape and heavier body compared to the others.

In Final Fantasy XV: Comrades, the Oracle's Sigil: Healing Light, enhances the bearer's curative spells.

Crepera, the Rogue[]

The Rogue.

Believed to be the first queen, the Rogue disliked the watch of the public eye and took to the shadows to enact her rule. She is known to have wielded a shuriken. Her statue and Lucii form has a thin suit of armor, a narrow waist cape, heels on her armored shoes, a horned crown covering her eyes, and a extensions on her shoulders adorned with four long ribbons.

In Kingsglaive: Final Fantasy XV, she jumps at the arriving Diamond Weapon and threatens it enough it uses its main attack. Her statue holds up a collapsing cliff after Niflheim's first attack.

In Final Fantasy XV: Comrades, the Rogue's Sigil: Aerial Ace, enables the bearer to perform a mid-air step after attacking.

She has an extended role in the Windows and Royal Editions of Final Fantasy XV, where she is fought as a boss in the final dungeon. Living guardian statues fashioned after her Lucii form also appear as bosses in Final Fantasy XV: Episode Ardyn.

The Tall[]

The Tall.

He is a king known by his girth and strength, alluded to like that of a mountain. The Tall is known to have wielded a chainsaw-like greatsword. His statue and Lucii form have broad, bulky armor, with a broad chest, and a comparatively narrow, but long cape.

In Final Fantasy XV: Comrades, the Tall's Sigil: Aura, enhances the bearer's attack power, but prevents them from casting curative spells.

The Just[]

The Just.

A queen who devoted all efforts to uphold peace and was beloved in turn by her peoples for her serenity. She is known to have wielded a tall shield. Her statue and Lucii form has incredibly large and heavy armoring, with large shoulders that have a three round holes, and thick, forward-facing horns on her helmet.

In Final Fantasy XV: Comrades, the Just's Sigil: Omniguard, enhances one to conjure a 360-degree protective barrier around the bearer and their allies.

Tonitrus, the Fierce[]

The Fierce.

A king famous for his personality; to his people, a kind, loving, and just king; to his enemies, a veritable demon of merciless brutality. He is known to have wielded a great mace. As a statue and Lucii spirit, Tonitrus had bulky, segmented armor, and a tattered cape on his left shoulder. His most prominent feature is the disc on his head.

In Kingsglaive: Final Fantasy XV, the Fierce wreaks perhaps the most damage, destroying buildings and imperial airships as he goes. Even after losing his arms the statue still continues but is the only statue who is defeated.

In Final Fantasy XV Comrades, the Fierce's Sigil: Rampage, allows the bearer to use powerful martial arts; when stringed together, the combos can unleash a powerful special beam of energy attack.

The Fierce is fought as a boss in the final dungeon in the Windows and Royal Editions of Final Fantasy XV. Living guardian statues fashioned after his Lucii form also appear as bosses in Final Fantasy XV: Episode Ardyn.

The Pious[]

The Pious.

A king known for his eponymous piety, leading Lucis with a rule guided by divine principles and worked closely with the Oracle of his era. He is known to have wielded a scepter that smote with a blade of light. His statue and Lucii form has light armor, with a thick cape draped over his shoulders, and a bishop-chess-piece-like helmet with a tall crown similar to that of a pope.

In Final Fantasy XV: Comrades, the Pious's Sigil: Multicast, enables the bearer to cast two offensive spells in a row.

The Warrior[]

The Warrior.

A king whose life was forever changed when his beloved queen was killed by assailants. He is believed to have wandered the world and waged an era of global war fueled by a vendetta of bereavement and is speculated to be the king whose worship inspired the Safety Bit accessory. The Warrior is known to have wielded a katana, a weapon not of the lands of Lucis, and is the only king laid to rest outside of his home nation. His statue and Lucii form depicts him with somewhat thick armor, a tattered cape, and a large volumed feathered tassel on the top of his spiky helmet.

In Final Fantasy XV: Comrades, the Warrior's Sigil: Untouchable, enables the bearer to provoke enemies and dodge their attacks. The bearer does a vacuum wave when dodging.

Regis, the Father[]

The Father.

Regis Lucis Caelum, the 113th king of the dynasty. He is known for the love for his family, and for wielding a saber-like sword. Regis made a trip across the lands of Lucis before his coronation and is the son of King Mors Lucis Caelum, who consolidated the power of the magic barrier over Insomnia. King Regis's Lucii adds a light suit of armor, and a sleek helmet that retains the horn-like extension that his crown had.

In Final Fantasy XV Comrades, the Father's Sigil: Revitalize, enables the bearer to restore comrades' maximum HP by sacrificing their own.

Other kings[]

Optimus Lucis Caelum, 108th king.

The Windows and Royal Editions add monuments to the three kings faced as part of the expanded final battle gauntlet. Each monument has the crest of "Optimus Lucis Caelum" the 108th king of Lucis, and the crest is different than the usual skull and angel wing crest used for Regis, instead having one feathered wing and one skeleton wing. Optimus could be the "The Wise" who erected the Wall approximately 150 years ago, as per average reign length. Number 108 is considered sacred by the Dharmic Religions, such as Hinduism, Buddhism, Jainism.

The True King[]

Noctis Lucis Caelum is the 114th king of the Lucian dynasty, and its last member. He was chosen by the Crystal to become the True King, the culmination of the Lucian bloodline as the member who can use the Light of Providence to eradicate Starscourge from the world.


Kings of Lucis stand beside the Oracle in the painting of the prophecy.

In the Old Calendar Era, Starscourge spread across the globe, a plague that lengthens the night and turns people into daemons. The Astrals want to purge the darkness and Bahamut handpicked two people who would become able to wield divine powers to counteract the plague, and to one day save the world from it. This became the prophecy of the True King.

As depicted in Final Fantasy XV: Episode Ardyn – Prologue, the Oracle was chosen first, and the world awaited the gods' decision on who to crown king. The decision was to be made between the two sons of House Caelum: Somnus, who ruthlessly rounded up the infected to exterminate them, and Ardyn, who traveled the realm alone to heal people by absorbing the malady into his own body. According to legend, Bahamut picked the first Oracle from the land of Tenebrae, and her calling is to help the king of Lucis. She has the power to commune with the Astrals and heal those afflicted with the Starscourge. Ardyn, the eldest son, was chosen by the Crystal to save the world and was to be the first king of Lucis. His ascension was thwarted when Somnus declared himself as the Chosen King and Ardyn was denounced as unclean and demonized by his brother whom Ardyn claims was jealous of him.

Somnus is said to have joined hands with the Oracle to travel the world and dispel the darkness that plagued Eos. According to Cosmogony they embarked on a journey across the land to forge covenants with the Astrals. Starscourge subsided by Somnus's hand, and peace was restored to the world that now laid in ruin in the aftermath of both the Starscourge plague and the War of the Astrals.

Bahamut gifted Somnus the Crystal alongside the Ring of the Lucii, so that one day the True King would be born of his lineage and fully banish the Starscourge from the world; though the plague had been pushed back, Ardyn's corrupted soul had become the Starscourge incarnate. The True King is said to surpass even the gods and have the power to banish the darkness from the world at the cost of his own life. The Lucian kings are sworn to protect the Crystal until that day arrives. The Crystal exudes great magical power, and is said to hold the soul of the world. Somnus ascended the throne and became known as the Founder King, whereas Ardyn's transition had rendered him immortal and was imprisoned in Angelgard.

Ardyn being celebrated as a great healer.

With the plan to cleanse the world of Starscourge in motion, Bahamut disappeared and the remaining Astrals fell into slumber. According to Final Fantasy XV: Official Works, the Astrals fell into slumber due to having overextended their powers, and thus it fell to the surviving humans to protect Eos with the powers the Astrals had granted them.[6] According to Final Fantasy XV -The Dawn of the Future- however, the true reason they rest is because they had defended Eos from Bahamut's Teraflare.

For the next two millennia the kings and queens of Lucis expanded their territory, extending the kingdom's sphere of influence to the regions of Cavaugh, Leide, Duscae, Cleigne and Galahd. Daemons eventually returned to the world and began to plague Lucis. A king and an Oracle embarked on a quest to seal the most ferocious of them in underground dungeons, a secret known only by few.

As told in Final Fantasy XV: Episode Ardyn, Ardyn was eventually released from captivity by agents of the Niflheim Empire. He took the surname of "Izunia", and vowed to have his revenge on the Caelum dynasty and the Crystal. He discovered he now has the power to daemonify others and thus spread the plague. He even daemonified the Astral of fire, Ifrit, who was surprised to meet a member of the Lucis Caelum lineage under such circumstances. The 113th king of Lucis is Regis Lucis Caelum CXIII, and Ardyn eventually travels to Insomnia to confront him. Ardyn wins against Regis whose Ring of the Lucii animates the Mystic's statue. Though Ardyn tries to get closure on their feud by felling him, the Mystic only wishes for Ardyn's salvation, realizing the mistakes he had made millennia ago. Bahamut removes Ardyn from the city before he can kill Regis, who is yet without an heir.

Fifteen years before the start of the game, the Lucii told Regis that his son Noctis will be the Chosen King spoken of in legend,[5] and Regis was chosen as a "ruler of yore".[7] Though crushed by the revelation, Regis tried his best to give Noctis a good life and a happy childhood. Though the Wall Regis upholds only now covers the Crown City, his health is failing him at 50. Regis ponders for how much longer he can keep projecting the Wall, but is reluctant to pass the torch onto his beloved son, knowing it would do the same to him. Regis eventually decides to accept a suspicious peace treaty with Niflheim, with whom Lucis has warred for hundreds of years, and sends the 20-year-old Noctis away from the city before the signing is to take place to keep him safe and to give him the best chance of fulfilling the prophecy.

Ravus wants to be judged by the Lucian kings and gain the Ring of the Lucii's power.

During the treaty-signing Niflheim's forces draw their weapons upon the Lucians and war breaks out amid the Crown City. Emperor Aldercapt and Ardyn—who has established himself as the chancellor of Niflheim—steal the Crystal and the Wall dissipates. The Crown City is invaded by daemons and magitek troops. General Glauca is tasked with taking the Ring of the Lucii from the king, and it is also sought by Ravus Nox Fleuret, the former prince of Tenebrae who is of the Oracles' bloodline. Ravus begrudges Regis and his kingdom for having abandoned Tenebrae when Niflheim invaded it, and believes his heritage entitles him to the ring's powers and could make him the True King. When he acquires the ring and puts it on however, he is judged unworthy by the past kings and the ring burns him, although he survives with a lost limb.

Regis is accompanied by Lunafreya Nox Fleuret, the Oracle and Ravus's sister who has never blamed Regis for Tenebrae's downfall. She is Prince Noctis's childhood friend and considers her calling to be helping him become the Chosen King. They are protected by a member of the Kingsglaive, an elite unit of soldiers for whom Regis has lent the ability to use his magic: Nyx Ulric. Regis passes on the Ring of the Lucii to Lunafreya with instructions to take it to Noctis. He stays behind to fight Glauca to give Lunafreya and Nyx time to escape, and is killed, his spirit entering the ring. The Kingsglaive lose their ability to use magic.

Nyx puts on the ring and communicates with the past kings.

Nyx is soon attacked by one of his fellow Glaives who has turned against the monarchy, Luche Lazarus. Luche is tricked into putting on the ring and is deemed unworthy by the past kings and burned alive. Nyx's superior, Titus Drautos, reveals himself to be Glauca, and attempts to claim the ring. Nyx puts it on and finds himself in another dimension, where he speaks to the rulers of yore and faces their judgment.

When the kings see Nyx fights for the future, at the spirit of King Regis's urging, they grant him their power in exchange for his life. Nyx passes the ring to Lunafreya, then uses the Ring of the Lucii's power to engage Glauca. The resulting battle sees Glauca fatally stabbed by Nyx, with the empire's Diamond Weapons destroyed by the Old Wall, summoned effigies of the past kings of Lucis. Nyx dies at dawn as part of the blood price of using the ring's powers.

Lunafreya escapes Insomnia with the Ring of the Lucii and eventually makes her way to Altissia where she speaks with her brother Ravus. She asks him to take the ring to Noctis as she is collapsing from the strain of her duties, but he turns away at the sight of it, and says delivering the ring to the Chosen King is her duty. Although Ravus doesn't think Noctis is worthy of Lunafreya's sacrifice, he has come to believe the prince is the only one who can become the True King.

Noctis is on a journey to collect the royal arms of his forebears and forge covenants with the Astrals with faraway help from Lunafreya. He believes his mission is to reclaim his kingdom by toppling the empire, and is initially unaware of the gravity of his role as the True King. He is being helped by Ardyn whose true identity Noctis is unaware of, and doesn't like or trust him. Ardyn has fallen from the gods' and the Crystal's favor and his name has been scrubbed from history books. He seeks to extinguish the Lucian bloodline as revenge, and defeat the True King. Knowing that this is Noctis's fate, Ardyn helps the prince get the full powers of the Crystal so that he could then destroy him.

Noctis wields the power of kings to fight Leviathan.

Lunafreya calls upon the souls of Lucian kings when Noctis fights the Astral Leviathan to forge a covenant with her. The kings answer, the royal tombs across the land light up, and Noctis enters a sustained mode of Armiger, the power of kings that lets him wield all of his royal arms simultaneously. As told in Final Fantasy XV: Comrades, Lunafreya releasing the magic of the tombs returns the kings' power to the former members of the Kingsglaive.

Noctis receives the Ring of the Lucii from a dying Lunafreya, and eventually makes his way to the imperial capital where the Crystal now lies. His mission has shifted from just reclaiming Lucis to that of saving the world, as without an Oracle keeping the darkness of the Starscourge at bay, daylight is rapidly vanishing from the world. Noctis believes he can use the Crystal's power of light to fight the darkness, but when he infiltrates Gralea his kingly powers are temporarily disabled by the imperial Wallbreaker Wave that can neutralize all magical phenomena exhibited by Lucian royalty. When Noctis finds the Crystal he is absorbed inside it. He meets Bahamut and learns he must sacrifice his life to bring light back to the world.

Noctis sleeps inside the heart of the Crystal for ten years, during which Eos is plunged into an eternal night and daemons take over the world. People's only hope is that the fabled King of Light of the Lucian lineage will come as per the prophecy. The Kingsglaive, the power of kings now returned to them, work alongside the Hunters and the Crownsguard to protect Lucis and mankind's final surviving outpost, Lestallum. The Glaives sport Royal Sigils bearing the insignias of the kings and queens of old, each possessing a unique power evocative of the sovereign to whom it once belonged. Some say the rulers of the past thus found a way to lend their strength to the warriors of the present.

The clash of kings.

Noctis returns ten years later. Noctis and his friends meet with Ardyn who stays with the Crystal at the Citadel. Ardyn places various obstacles upon Noctis's way, including the Fierce, the Rogue and the Mystic now enslaved by the Starscourge. Noctis overcomes them and battles Ardyn both wielding the power of kings. Late into the battle, five of the kings appear at the perimeter of the Citadel's ruins, with Ardyn indicating that their presence is to call Noctis forth to oblivion. Noctis emerges victorious and ultimately kills Ardyn by drawing his royal arms and striking him with each one.

He calls upon the spirits of past Lucian kings to confront Ardyn's spirit in the afterlife. The spirits of the old kings attack Noctis until his soul is taken by the ring, and his spirit enters the beyond. The royal arms the Lucii had plunged into his body emerge from him, and the kings combine their powers to banish darkness from the world and erase Starscourge from Ardyn's soul. The prophecy fulfilled, the Ring of the Lucii disintegrates as the Lucian bloodline ends with Noctis's death. Noctis appears upon the throne of Lucis marked Noctis Lucis Caelum CXIV with Lunafreya Nox Fleuret, the last Oracle.

Alternate endings[]

Final Fantasy XV: Episode Ignis depicts an alternate ending where Noctis doesn't die, and stays to rule Lucis as its king after Ignis Scientia seemingly devises an alternate method of purging the darkness from the world.

Final Fantasy XV -The Dawn of the Future- depicts yet another alternate ending to the saga where Ardyn accumulates power too great for the Ring of the Lucii to purge, and Bahamut decides to destroy all life on Eos to cleanse the Scourge. During his sleep inside the Crystal Noctis learns of the world's history as well as the history of his lineage. Noctis, Ardyn, the Lucii, the revived Lunafreya and the other Astrals eventually combine their forces to defend Eos from Bahamut's megalomania. Ardyn sits on the throne with the Ring of the Lucii and is impaled by the Lucii so they may emerge in the Beyond and fell Bahamut's spiritual self, while Noctis and the others fight the Sword God in the physical realm. Light returns to the world, but the Astrals fade and the Crystal shatters. The Lucis Caelum lineage doesn't end, as Noctis doesn't die, ready to live the rest of his life happily with Lunafreya.


Battle against The Fierce.

The player can visit numerous royal tombs across the land to inherit the kings' royal arms. Some are optional while others are obtained as part of the story. In the Windows and Royal Editions, collecting all 13 royal arms and interacting with the monument of the Mystic in Keycatrich yields the Founder King's Sigil that lets the player use a new form of Armiger, called Armiger Unleashed.

The Fierce, The Rogue, and The Mystic are fought as bosses in Insomnia in the PC and Royal Edition versions.

Musical themes[]

"Kings of Lucis" is a track on the Kingsglaive: Final Fantasy XV: Original Soundtrack, which accompanies the Lucii's appearance in the movie. In Final Fantasy XV Windows/Royal Edition, the boss battles against the Lucii were added with new battle music specific to these encounters.

Behind the scenes[]

The kings' spirits in the sky in the Dawn trailer.

The Lucii first appeared in the Dawn trailer shown at Gamescon 2015, where Regis holds the young Noctis at a rainy Citadel with the shadows of the Lucii looming about them. This scene doesn't appear in the final game, but appears to depict the scene where Regis learns of Noctis's status as the Crystal's Chosen.

Visual effects studio Image Engine created the 23-minute battle scene where the Lucii come to life for Kingsglaive: Final Fantasy XV. Square Enix sent Image Engine a variety of environments and other assets at the start of production, and Image Engine commenced the animation process using body and facial motion capture provided by Square. In addition, Image Engine's own animators donned Xsens MVN suits to capture in-house mo-cap data. The animators even filmed themselves acting out fight scenes with cardboard swords, working with a martial arts expert who helped provide direction on combat choreography. Sequence director Yamamoto Kazuhito stayed at Image Engine's Vancouver headquarters to work with the team. For Insomnia, Image Engine team produced a library of buildings, many of which were intended to be destroyed by the Lucii, and populated them throughout the city based on a guide map provided by Square Enix.[8]

Other appearances[]

Dissidia Final Fantasy NT[]

The Lucii loom over the Citadel square.

Insomnia appears as a stage. The arena is the outside of the Citadel where the full game's final battle is fought. Its night version has the thirteen Lucii watching over the arena.

Etymology and allusion[]

Lucis, meaning "of the light", is the genitive singular form of the Latin word lux, which means "light".

Caelum means "sky" in Latin.

There being thirteen past kings who aid Noctis in his final struggle, as well as thirteen royal arms, is an allusion to number thirteen, as per the game's origins as Final Fantasy Versus XIII. The Lucian kings could be compared to l'Cie from the Fabula Nova Crystallis: Final Fantasy series to which Final Fantasy Versus XIII was part of, as they have a mission to a Crystal. "Lucis", "Lucii" and "l'Cie" sound similar, although this could be a coincidence. Both the Lucian kings from Final Fantasy XV and l'Cie from Fabula Nova Crystallis are also homage to Warriors of Light, the traditional Final Fantasy heroes who answer the calling of a crystal.
