3rd Person Pov

In the year of 999 B.C, there stood a man that was crowned King, well, born one. However, he did not seek omnipotence, only knowledge.

Given miracles by the god, he used it once to create a city for himseld. His ten rings hold dominion over all magic. He saw the future and past, along with building the 72 Pillars at his service. The summoning spell was named Goetia.

In the year of 900 Bc, where a famine started, his cruelty was known and he did nothing but had a thin smile. Despite having all knowledge, he did nothing at all.

In Chaldea in 2016, no one chatted, no one took a break as they were planning a route to the Temple of Time and will make contact with the last singularity in 4 hours as Dr Romani was alone in the control room with Fou.

He did nothing but research and study. However, coming to Chaldea changed him a little. So, he had done everything he could. Scared, but happy.

As for Solomon, Romani had some kind of idea. Kingu, or Enkidu was a good sample case. He would have one weak point, if he was the real Solomon, then there is a void somewhere.

Y/N heads to Da Vinci where he was told to try out a new mystic code for the final battle

You: This feels different

Da Vinci: Indeed. That one isn't like the others before, which were to explicitly keep you alive. Your equipment is to protect you. Now, since we are putting our lives first, this equipment is for you to fight.

Da Vinci then explains what the code does. As long as Chaldea has electricity, physical protection is confirmed and it allows servant summons with the master's powers. No relics needed and a heroic spirit will arrive, although only for a split second.

Combat isn't a problem, so nothing is added. As for Y/N's powers, they didn't know much and yet, they made a suit that utilises his combat style.

You: Thanks, Da Vinci. Everyone did their best. You, everyone, Olga, the Doctor. So, I won't back down without a fight

Time skip

After taking off the suit, Y/N asks about Mashu and her body is at her limit, meaning the last operation will be her last, meaning that she would be killed. Mashu would know either way even though she wasn't told about anything

Mashu knew that she would die soon, and Y/N had to accept it. Carrying a burden while fighting alongside everyone, meeting many servants, and yet... still dying.

You: She definitely has no regrets...

After that talk, Y/N meets the girl in the same hallway that they reunited. Y/N didn't want to bring Mashu, Chloe, and Illya since this mission would kill them. They were kids, but only Mashu wished to head into battle with Y/N.

Mash: Ever since I met you, I always wanted to stay by your side, even if my time is short. It is unfortunate, but I don't feel any regrets in my life anyways.

You: ...

Mash: Solomon said human life had no value. However, the way you stood by everyone you met, those who you reunited with such as Kiyohime, Jeanne, Ishtar, Ereshkigal, Tamamo, Nero, Mordred, Jack, Karna, Bedivere, I've learnt so much form this journey. So, I have no experience with sorrow, only joy. So, let me accomplish you, one last time, Y/N Emiya Von Einzbern

You: Yes, let's do this... haha, you too Fou.

They were then called into the room as Romani and Olga explains the mission one last time. Back on land, humanity had fallen, but in space was different. That timeline was 900 B.C and also 2016 A.D.

If they could defeat the king, humanity will be restored. Defeat Solomon and return.

You: When we get back, let's celebrate.

Video showed the arms and legs of Solomon. Y/N is the only mage that can go to the place

Olga: I am expecting you to finish this mission. Put an end to this madness!

You: Right!

The two were then rayshifted and as they got out, they arrived somewhere in a cave like place. Breathing and consciousness was alright.

Da Vinci: You're used to driving, right? Hop on!

A moon buggy made from Da Vinci herself then appears as Y/N hops inside before Mashu does.

You: Just like Da Vinci!

They then drive off to the temple and nothing seems out of the ordinary. Solomon was also a great summoner and a servant. He had 10 rings of god before returning them to god

Upon driving closer, they were attacked by not only Solomon, but by energy waves

You; Let's see if my mom's bad driving makes something of me!

Y/N dodges all of the beams while Mashu protects the back. If there was something Y/N was proud of, it was that he had Irisviel's bad driving skills.

However, it didn't last as a compressed wind blade slices the car in two

You: Lev Lainur!

Lev: Indeed. I was sent by Solomon to destroy you, no die!

He takes out his staff as wind blows. Lev wanted to destroy humanity and it was part of Solomon's plan, the Grand Order. For Chaldea was to continue humanity while Solomon was otherwise.

Lev was the seed, the last one of Solomon before he starts controlling the tentacles.

Lev: Now, let's see how much you learned, Final Master! My name is Demon God Flauros! One of the 72 gods!

You: Where are the Knives?!

A red circle of knives then form as it forms a knife blade which was as big as a normal sword. However, this sword was implanted with Balmung, the blades of Ezel, and Excalibur, so Y/N had nothing to fear

Tentacles then surround the duo as it breaks the ground before protects Mashu with immense speed.

You: Looks like I won't be able to do this on my own! Heed my words. My words create your body, and your sword creates my destiny. If you Heed the Grail's call and obey my will and answer, then answer my summoning! I hereby swear that I'll be all the good in the world, that I shall defeat... all the evil in this world! Then let thine eyes be clouded with the fog of turmoil and chaos, thou who art trapped in a cage of madness, and I, the summoner, who holds thy chains. Seven Heaven Clad and the great words of power, come forth from the circle of bindings, Guardian of Scales!

Light was then summoned as another servant appeared, an old friend perhaps, from the first Holy Grail War that Y/N participated in

Alexander; My name is Alexander Iskandar the III!! From the bonds of reminiscences, I will assist in this battle! Yo, Y/N, been a while huh?

You: Indeed it is, Broskandar!

Alexander: Haha! I will be in your care as I fight for you in this battle! Go, Bucephalus!

The horse then charged as Alexander rushes with lightning as Mashu followed Alexander as Y/N supports them by slashing the tentacles and blocking magical shots

Alexandar then rushed towards the sky, destroying the terrain with his lighting. As for Lev, he wasn't left alone as he was almost slashed by a Dark Japanese Katana

???; You won't get away!

As Lev fights back, a servant by the name of, Sanson, had to retreat for now as Iskandar goes in for the attack

Alexander; O cloud of Darkness! O lightning! O father! Behold! Bucephalas!

Lightning raged on as Iskandar was able to stab Lev before disappearing

Alexander: Y/N, I'll leave the rest to you!

However, another dark energy appeared as another servant was able to rake Iskandar's place

Vlad III: Hell incarnate is the reward for your depravity! Heh... Kazikli... Bey!

Blood then turns into sharp objects as Lev flies into the air as another Noble Phantasm grabs Lev to cut off his head

Sanson: My Noble Phantasm... La Mort... Espoir... execution complete

You: That was just 3 servants... and I'm already feeling the effect...

Another signal was found as another set of tentacles were summoned.

You: Damn!

Mash: Can't you do something?!

You: No, Overwrite effects everything, it wouldn't do much if Solomon is-

Y/N then watches as Lev destroys Chaldea ad they manage to hold on for a little. To kill Lev, they had to destroy all the Tentacles. However, that wad merely impossible as memories of the singularities appear

The first, Naberius, the melting Furnace. The second, Flauros, the information center. The third, Forneus, observation, 4th, Barbatos, the control tower. The 5th, Halphas, armoury. 6th, Anon, the Gazing Star. The 7th, Sabnock, the chamber of life.

You: Ah! This is... human history... ah!! My head!!

Lev: The final master, you are truly amusing! However, this will be the end of you! You shall be incinerated before your beloved Director!

???: Like I'll allow you to do that. The ones who stand before you are the proof you need.

You: Jeanne?

Jeanne: Fragile humans that you demons mocked, that they would never reach you

Stars start to move as Jeanne stands in front of Y/N as her flag flows. Many then followed as well

Nero: Master, Umu! Were here too!

Bedivere: Indeed, don't leave us out just yet just because you saw us die you know!

Multiple servants from every singularity appear as Jeanne holds Y/N's face

Jeanne: Lift your heads, my husband. Wasn't this story meant to get the future back?

You: If you're here...

Olga: Yes! Servants from every time, every era, every history book has come to help us!

Siegfried: Let's hope that we aren't too late, Y/N

You: Siegfried!

Siegfried: Yes, you did well to carry Balmung and my spirit, Sieg is too.

You: Sieg?

Sieg: Caster Class Servant, Sieg Emiya Gon Einzbern, reporting for duty!

Lev: Impossible!

Jeanne: And yet they are all here to lend aid! So they could respond to the world and made it all the way here suffering all the while, but never giving up.

You: Hmph. Miracles can happen...

Jeanne: Y/N, it is appropriate for you to say a speech to them.

You: Right... Hear me! Heroic spirits who come from afar! Mighty warriors who have gathered here! Though we may be rivals, or enemies in our past lives, or from completely different eras, we must stand together here now as one! My name is Y/N Kasai Emiya Von Einzbern, the last heir of the Einzbern and Emiya bloodline! In the name of victory, let us ride into victory and let me be your shield!

Y/N and Jeanne nod as Y/N equips the same flag as Jeanne

You/Jeanne: O flag of mine, protect our comrades! Luminosite Eternelle!

Once piercing the ground, it creates a shield which protected all the servants from the blast as Y/N and Mashu ride Alexander's horse

You: This is...

Jeanne: Leave this to us! Now go!

You: Hai, thank you, Jeanne!

A tentacle then tries to reach for Y/N as Nero comes in as stops it

Nero: Like I'll allow you to harm him!! For Rome, for the Red Sabers!! UMU!!!

As the servants kept Lev busy, Y/N and Mashu head towards Solomon as Y/N sees that such a miracle between servants can exist.

You: Nero, Artoria, Scathach, Atalante, Scathach, Skadi, Gilgamesh, Gorgon, Ana... everyone...

Mash: Guess you owe them too much now

You: Yeah, and I'll repay then by destroying Solomon!!
