Noctis opens the doors to the throne room, puppets of people were hanging by chains.

Prompto: (gasp) What is that?

Y/N: What the hell...?

One puppet was of a Glaive, Nyx Ulric, who had given his life to defend the Crown City. The next one was Lunafreya, Noctis's beloved. The next one was his father, Regis. And the last one was the older brother of Lunafreya, Ravus.

Sitting upon the throne was none other than Ardyn himself. Upon seeing the Chosen King, he grins.

Ardyn: I'm afraid you're out of luck. The throne brings you here? (chuckles) It seats only one.

Noctis: Off my chair, jester. The king sits there.

Getting up, the former chancellor of Niflheim stomps his boot on the stone chair, his grin growing wider.

Ardyn: Oh, Noct...how I have waited for this. Longer than you could ever know. Tonight, the dreams of the blood royal...come to an end.

Gladiolus: Spite's all that's kept him going.

Prompto: Hmph. Talk about a grudge.

Ignis: Ardyn sits the throne?

Y/N: It was never his.

Noctis: (scoffs) Not for long. This is my ascension.

Ardyn then casts a spell, orbs of darkness sending themselves to the four Kingsglaive members. They soon fall to the ground, clutching their chests.

Noctis turns around, shocked that all four of his friends had fallen.

Noctis: What did you do!?

Ardyn: They have no place in this, the battle of kings! Come, Noctis!

The first Caelum then disappears, Noctis looking to his friends once more. He then runs up the steps that led to the throne, the fake bodies of the four people dangling disappear.

Noctis: It ends now.

Running out of the hole on the left side of the room, he point-warps to the front of the gates of the Citadel.

Ardyn: The once helpless and hapless prince. Is he now ready to claim his crown? Don't let us down.

The two then conjure the Sword of the Wise, throwing towards each other as they warp-strike, the tips of their blades clashing together.

The clashing of the two blades had sent them back, crashing into the windows of the buildings behind them. They both quickly recover, warping back to the ground, the buildings behind them collapsing.

Ardyn: Let the games...begin.

Noctis: No. Now they end.

The two then start to clash, using copies of the same royal weapons they were using. First they zipped around using the Katana of the Warrior, then switching to the Swords of the Wanderer as they have a brief duel.

Noctis was then sent into the air, Ardyn having shield bashed him with the Shield of the Just. But Noctis warps back down with his Ultima Blade, rushing forward as he uses the Sword of the Tall, the razor-chainsaw area grinding against Ardyn's copy of the Shield of the Just. The former chancellor had then forced him off, conjuring the Blade of the Mystic as he lunges forward.

The Chosen King then rolls out of the way, using the Ring of the Lucii as he uses once of it's spells, healing Noctis as Ardyn slowly suffers damages. But Ardyn ceases the king's attacks, using the Bow of the Clever as Noctis begins to phase in order to dodge the arrows.

Ardyn: So you are the Chosen King...but you are a second choice, at best.

Conjuring the Sword of the Father, Noctis warp-strikes Ardyn, who had conjured the Sword of the Wise as the two begin to duel once more.

The first Caelum then kicks Noctis in the gut, sending him to tumble backwards as Ardyn sent a blast of energy towards him. Summoning the Shield of the Just, Noctis begins to slowly be pushed back, grunting as he looks for a way to counter. Ardyn cackles as he warps behind Noctis, but the Chosen king reacts quickly as he turned around, conjuring the Mace of the Fierce and swung it, striking Ardyn in the face.

Noctis had then charged forward, conjuring the Trident of the Oracle, but Ardyn had conjured the Scepter of the Pious, the two attacking at a distance as they thrusted their weapons forward.

Ardyn then switches the scepter for the Blade of the Mystic, coming down for a powerful strike before Noctis had summoned his Armiger, the royal weapons circling around him as they begin to protect him from Ardyn's strikes. Noctis then jumps into the air, a wave of fire leaving Ardyn as he begins to laugh.

Ardyn: Do you like what I've done with the world? I twisted it all...just for you.

Noctis doesn't respond, warping to a high area as he hangs by the Ultima Blade's handle, his MP restoring. He then warps back to the ground, summoning two copies of the Star of the Rogue, throwing them with weapon's curved arc. But the stars were easily deflected by Ardyn, who had conjured the Sword of the Tall.

Then, Ardyn had lunged forward, attempting to strike with the Blade of the Mystic, but it was parried by Noctis's Sword of the Father. Now having a window of opportunity, Noctis begins to strike Ardyn as fast as he could with his Ultima Blade.

However, the former chancellor recovers, kicking Noctis off of him once again as Noctis begins to skid across the road.

Ardyn: A king in name only. I'm truly disappointed. Can't you do any better than that!? Ten years, and nothing to show for it!

As Noctis recovers, his eyes were growing a bright red. From the distance, Titan could be seen. The Archaean then grabs a large piece of the road, hurling it towards Ardyn.

Ardyn was being severely damaged, the shards of the road shattering as it destroys the buildings nearby. A dust cloud had formed after, it soon clearing as Noctis had warped through to attack Ardyn, but he reacts by kicking Noctis again.

Ardyn: Even were the dawn to break now...it would only bring the horrors to light!

The Chosen King grits his teeth, standing up as he takes a few ice spells, casting them on Ardyn. But it's potency wasn't strong enough, Ardyn freeing himself without effort.

Once again, Noctis warp-strikes Ardyn, the attack connecting as he starts to do a combo with the Sword of the Wise, doing a flurry of strikes and attacks. He then ends the combo by conjuring the Axe of the Conqueror, swinging it upwards as Ardyn was now launched into the air. Noctis then takes the Sword of the Father, warp-striking upwards as an afterimage as left, still damaging Ardyn.

But Ardyn then warps onto Noctis, the Chosen King falling onto his back as Ardyn grabs his face.

Ardyn: Ah...my revenge is soon at hand...how long have I waited...?

Noctis: (grunts) Don't worry. It's far from over.

Ardyn: Well, let's have it, then. You and your Crystal...against all I have become.

After Ardyn had picked Noctis up and shoved him off, the two summon their Armiger's, Ardyn's being a shade of red.

Noctis: Power...of light!

Ardyn: Ahh, a king! At last!

The two then fly into the air, zooming across the city as they sent their royal arms at each other. The spectral forms of them would explode, dealing damage to the other if they were caught in the vicinity of the blast radius.

The two continue to clash in the air for awhile, zooming around the Citadel. Then, Noctis calls upon all of them, sending them out at once as they explode upon impact when it got near Ardyn. Both of them then fell to the ground as their Armiger's deactivate.

Ardyn: (coughs) A war...of attrition, then.

Noctis used the Blade of the Mystic to support him up, him struggling to stand as his legs shook.

Around them, ethereal figures of the Kings of Yore start to appear.

Ardyn: The Kings of Yore are on hand. Calling you forth...to oblivion.

Weakly, Noctis begins to slowly make his way to Ardyn, the two clashing with the Sword of the Father.

Ardyn: Yet when your father died...you were off playing with your friends! When your beloved died...you lay watching, powerless to stop it! You think ten years is a long time!? It is nothing to me! I have lived in darkness for ages!

The two don't relent their attacks, Ardyn laughing in joy as Noctis grunts with anger and frustration. Then, Noctis warps to the side, striking Ardyn. He warps again and strikes him from the other side. Another strike as he warped behind.

He kept warping around him, using the different royal weapons each time he warped. With the final thrust, he thrusted the Sword of the Father forward.

Ardyn: So, that is how you would end it.

The first Caelum then starts to fall backwards, lying on his back as the rain starts to fall. Ardyn was weakened. The ethereal Kings of Yore begin to disappear, knowing who won the battle.

Ardyn: Now it is over, Majesty. What will you do? Banish the daemons and bring peace? Erase me from history once more?

Noctis: This time...you can rest in peace. Close your eyes...forevermore.

Ardyn: I will await you...in the beyond.

The first Caelum then starts to burn, disappearing into ashes.

(A/N): Here's a visual if you want to see it. Imagine yourself in the scene depicted. I don't own the video.

https://youtu.be/xhXN7A5UlRQ

Soon after, the four Kingsglaive members gather outside, Noctis standing on the steps as his friends wait at the end.

Ignis: ...So this is farewell.

Noctis: Yeah. Here we are.

Gladiolus: It's all you.

Noctis nods as he turns around, making his way up the steps.

Prompto: No turning back now.

Y/N: (holds in tears) It's the end of the road.

Halting halfway up the steps, he turns around one more time.

Noctis: Prompto. Gladio. Ignis. Y/N. I leave it to you. Walk tall...my friends.

Ignis: Godspeed...and take care. Majesty.

The four of them then salute towards their king, bowing as Noctis salutes back. Behind them, the low growls of daemons were heard as Iron Giants rise up from the ground.

Noctis: The time has come.

The Chosen King starts to ascend up the steps, the four friends turning around as they ready their weapons, once more raising their weapons for their king.

Noctis soon arrives in the throne room, slowly making his way up the steps.

Noctis: (sighs sadly) I'm home. I walked tall...and though it took me awhile, I'm ready now.

He then sits on the throne, the Ring of the Lucii starting to glow.

Noctis: I love you all. Luna, guys...dad.

Then a ghostly version of Regis appears next to the throne.

Noctis: The time we had together...I cherish.

Then, the light begins to shine down upon him, Noctis looking up with his eyes closed.

Noctis: Kings of Lucis...come to me!

He opens his eyes, conjuring the Sword of the Father as he stabs it into the ground. The Kings of Yore begin to rise up from the ground, their respective weapons in front of them.

The Mystic had float down, slowly.

First, the Wise had flown up, reading his weapon as he dove straight for Noctis, the ethereal piercing him as the Chosen King grunts in pain. Then it was the Warrior. And one by one, the Kings of Yore stabbed him, the second to last being the Mystic. Noctis then falls, the Sword of the Father falling. But he picks himself back up, remembering his loved ones. Gladiolus, Ignis, Prompto, Y/N, then Lunafreya.

He then hands his father's sword to the spectral beside him.

Noctis: Dad...trust in me.

And finally, Regis picks up his glaive, readying his weapon as Noctis looks up at him, one last time. Regis lunges forward, the Sword of the Father piercing him. Noctis Lucis Caelum had passed.

The Ring of the Lucii then explodes, engulfing the entire area in light. In the Astralplane, Noctis floated down as Ardyn awaited him, tipping his fedora. Then, the spirits of Regis, Y/N, Prompto, Ignis, and Gladiolus appear next to Noctis.

Extending his hand, Ardyn does as well in hopes of eliminating him one last time. But the spirit of Lunafreya then grabs his hand, Ardyn beginning to glow as the Scourge begins to be purged. The royal arms leave Noctis's body, the Kings of Yore appearing before Ardyn as Noctis screams in agony, the blood price being paid. Sending them forward, the Kings of Yore purge Ardyn and the Scourge. Noctis then falls, crystallizing as he now disappears, the Ring of the Lucii being destroyed.

Noctis: It's finally over...

In Lucis

(A/N): And here's the wedding scene.

https://youtu.be/m5EjhqUBKW0

The light was beginning to return everywhere. First it was Insomnia, then Lestallum, then Hammerhead. The last area being shown where the group had their final camp. The last campfire. 

Umbra could be seen at the bottom of the steps, watching the sun rise.

Regis: Dearest, Luna.

The next shot shows as the camera slowly pans up the stairs towards the throne. A banner that displayed the words "Noctis Lucis Caelum CXIV."

Regis: You did well to deliver the ring to Noctis. Wayward though my son may indeed be...he has made me proud. May you two know happiness.

It then brings the camera to the shot of the picture on the armchair. On the armchair, it was the same picture Noctis had picked out before he went into the throne room.

The same group picture they took in the hidden harbor of Caem.

(A/N): In the video, it's the picture of them in Hammerhead, but imagine it's the group picture of the hidden harbor in Caem.

A white gloved hand appeared, revealing it to be Noctis's, him sitting upon the throne. Noctis smiles as he hands the picture to the person next to him, which was his beloved.

As she gazes at the picture, smiling, Noctis removes his gloves and the two look at each other, giving each other smiles. They soon met for a kiss and released, now closing their eyes as Noctis rests his head on his hands and Lunafreya rests her head on the arm rest of Noctis's throne.

The two then rested there peacefully.

A black screen could then be seen, the humming of a car engine in the background. 

Gladiolus: Can it.

Y/N: Ready...

Prompto: (groans)

Gladiolus: Steady...

Noctis: (sigh) Really?

Gladiolus: Push!

The grunts and annoyed complains of Prompto and Noctis could be heard.

Noctis: Un. Believable.

Gladiolus: Not exactly a fairy tale beginning, huh, Prince Noctis?

Ignis: We let ourselves get carried away.

Prompto: L-Look, these things happen!

Y/N: Yeah, not under normal circumstances.

Gladiolus: Let's just hope this isn't some omen.

Noctis: Gladio, Y/N, do me a favor.

Gladiolus and Y/N: (strained grunts) What?

Noctis: Push this thing by yourselves.

Gladiolus and Y/N: All by ourselves!?

Prompto: You won't even notice if we just let go.

Gladiolus: Prompto...don't even think about it.

Ignis: Save some breath for pushing.

Noctis: Ignis, c'mon--time to switch!

Y/N: Nope! We just switched back there!

Prompto: And it's my turn, Noct.

Ignis: His "turn."

🎶When the night has come
And the land is dark
And the moon is the only light we see🎶

🎶No I won't be afraid
No I won't be afraid
Just as long as you stand, stand by me🎶

🎶And darling, darling stand by me
Oh, now, now, stand by me

🎶If the sky that we look upon
Should tumble and fall
And the mountain should crumble to the sea

🎶No I won't shed a tear
Just as long as you stand, stand by me
And darling, darling stand by me🎶

🎶Oh, stand by me
Stand by me, stand by me, stand by me🎶

Gladiolus: (grunts) You guys even pushing!?

Y/N: Maximum effort!

Prompto: Hard as I can!

Noctis: With everything I've got.

Ignis: We'll be there in no time.

Prompto: Check it out!

Noctis: What?

Prompto: Up ahead, the sign!

Gladiolus: Nice.

Y/N: Huh, neat.

Noctis: (irritated sigh) You made me think we were close.

...

...

...

Gladiolus: Hey, is that all you got?

Noctis: Pretty much.

🎶And darling, darling stand by me
Oh, stand by me
Stand by me, stand by me, stand by me🎶

🎶Whenever you're in trouble won't you stand by me
Oh, now, now stand by me
Oh, stand by me, stand by me, stand by me🎶

🎶And darling, darling stand by me
Oh, stand by me
Stand by me, stand by me, stand by me🎶

🎶Whenever you're in trouble won't you stand by me
Oh, now, now, stand by me
Oh, stand by me, stand by me, stand by me🎶

Before

It was before they had departed for the Insomnia, the five friends had gathered around their final campfire.

Noctis: The five of us around a campfire. How long's it been?

Ignis: Hmm...an eternity.

Y/N: Yeah...it felt like a lifetime ago.

Noctis: So, yeah.

There was a long pause, the other four members looking to each other. Noctis was struggling to get words out of his mouth.

Noctis: I, um...

Gladiolus: Out with it.

Noctis: I just... (clenches fists and sighs) ...Dammit. The hell is this so hard?

He clasps his hands together as he looks to the fire briefly, the bright orangish-yellow flames illuminating his eyes.

Noctis: So, I... (looks to everyone) I've made my peace. Still...knowing this is it, and seeing you here, now, it's...more than I can take.

His voice was breaking as tears start to stream out of his eyes. The others look down, wiping away their own tears.

Prompto: Yeah. You're damn right it is.

Gladiolus: Huh. You spit it out.

Y/N: Yeah...he did.

Ignis: (long sigh) It's good to hear.

Noctis then stands up, a small smile present on his face as he looks to his friends one by one. All four of them having sad looks.

Noctis: Well...what can I say? You guys...are the best.

The screen then fades two darkness. Their journey was over.
