Thanks for encouraging comments.

Chapter 1: Prologue

(Shirou POV)

"Who are you?" The Greatest of all Dragons asked me. His red body, tall enough to dwarf the Himalayas and wide enough to outstretch the continents were scaled like armour that has never been and never will be pierced.

With courage not my own, I stared back unflinchingly.

"Who are you, Emiya Shirou?" The Great Red asked me as we stood in the dream of my soul. The Gears that forged the strongest of blades continued spinning above us in the eternal realm of Unlimited Blade Works.

"Who are you to make fire dream?!" The Dragon roared and my world erupted in fires. The chains of Enkidu binding the One born of Dreams melted, my bones made of blades melted and yet I didn't fear.

Oh mother of all that is holy, why didn't I fear.

My dreams came into reality, for a defined measure of reality.

AVALON.

Trace Overedge!

I didn't spoke as much as I thought so loud that everyone in this dimension would have heard.

The greatest of Ancient Fae artefacts came into existence between us and defended me. Its exaggerated dimensions matched the Great Red and parted me from the heat of his wrath, defending me at the same time healing me.

Healing me but not fast enough. Well that can be rectified.

Excalibur.

The crystallization of Human's hope, the Last of Noble Phantasm and Sword of Victory was sheathed into the oversized scabbard. Fitting perfectly despite their size difference due to Fae Magic. Bolstering healing and defence of Avalon.

My body healed back in the instant. That's better.

"Amazing." The voice was tinged with actual awe before it dissipated back into deep, guttural voice I associated with the Dragon.

"To be capable of replicating Lost Fae Magic? It certainly gives you credit, doesn't it, Lord Emiya" the Dragon said.

For the first time since I entered this dimension, I parted my lips and spoke.

"Please call me Shirou, Lord Emiya was a cunt." My eyes, if the dragon could have seen, filled with magic as I prepared my strongest attack.

"Shirou it is." The Dragon accepted even as its eyes snapped open from the near infinite prana output it felt from around it.

"Oh and what would this be?" Unbothered by what it probably had already discerned, the Dragon asked. No matter.

Trace Overedge, Superanumery Manifestation.

The Excalibur-Avalon due replicated in a bizarre manner, enclosing the great dragon like the great walls of China in a manner similar to how a sheep herd would be enclosed.

But it wouldn't be enough to merely capturing the dragon, when the dream faded away, so would the Avalon freeing the majestic creature once more.

And that was a limitation that didn't apply on his opponent. Unlike his dream, the Dream of the Great Red was an eternal one.

His Aria came again once more to his lips as he chanted.

My body is made out of swords.

A divine construct began taking shape in a place far away, yet within the realm of his imagination all the same.

 My blood is of iron and my heart of glass.

Fae Magic, impossible for humans to understand the slightest yet on my very command came into existence, forging the divine metal.
I have overcome countless battlefields.

"Are you seeing me now, Saber?" I asked once more to someone that I used to know.
Not even once retreating,

In between lives, an eternity lied before my eyes. In the land of Avalon, every happiness and every magic had been mine.
Not even once being victorious.

The sword had finally been sheathed in its beloved scabbard.
The bearer lies here alone, forging iron in a hill of swords.

But now it was time for the sword to be drawn once more.
Thus, my life needs no meaning.

An eternity I had rested in the holy lands of Avalon but now an Emiya Shiro had a need for his Unlimited Blade Works once more.
This body is made out of infinite swords.

With a promise that I would seek an eternity with her once more, I had left the Holy Lands.

Unlimited Blade Works: Creed of Magic

The one True Magic, the one that I Faked during my two century of lifetime. The one that exceeded all other Magics and far exceeded mage crafts of all kind. The one that defeated the very manifestations of planets like Type Mercury.

A sword divine and magnificent came into existence above the equally magnificent dragon causing the reptile to take in the sight of a sword whose name everyone would know by merely looking at it.

"Excalibur..."

Hope, flawless and firm.

Perfect in measure that even the Fae of the Great Lake of Avalon couldn't differentiate in the original and the construct.

So perfect that universe itself couldn't accept that the construct was anything but original.

But it was merely the First Magic that he was capable of in this realm. The Denial of Nothing, the ability to create everything from nothing. Ability to withdraw Excalibur itself from nothing but a thought.

[Stage 2]

Second Magic, Operation of Parallel World. With another thought, the sword whose name no one knew came into existence. A sword which I had forged from endless study of Zelretch's Jewelled Sword. A Mystique code that belonged only to Shirou Emiya.

As soon as it came into existence, it faded away. Destroyed by sheer unrealism of what the sword was. An anathema rejected not by Gaia but by Universe itself. Nevertheless, it had completed its function.

A rupture occurred in the reality of my dream's fabric. A rupture across parallel universes directly into a universe made of infinite prana. Prana that was now in the domain of my dream. Mine to do as I please.

[Stage 3]

Now this was going to be tricky.

People called me by various name. Iron Wrought Mage, The Fake Sword, Second Mage Killer or perhaps most famously the Fake Magician but it wasn't true.

While I was capable of a portion of all five magics, I wasn't a magician in a traditional sense since regardless of my capability I would never be capable of withdrawing entire castles as Lord Emrys or King Solomon were able to with The First Magic, nor would I be ever able to transverse numerous universe like Zelretch was able to.

The true reason I was called Fake Magician was this. Individually my magics were nothing but degraded fakes but in a tandem was where the potential lied.

Third Magic, Heaven's Feel.

In an instant, another sword that belonged to only Emiya Shirou materialized and stabbed me in the heart. The ability to anchor to soul to a reality cutting it off from passing on for a while. Immortality and Invulnerability for a minute.

If only the fucking prick Jubstacheit could see me now. Fucking Einzberns probably masturbated to this magic. Guess who is nobility now, bitch?!

Fifth Magic: Magic Blue

This time the dragon's eyes snapped open in horror as he screamed.

"EMIYA, WHAT THE HELLLLLLLLLllll..."

His words were distorted as a sword self destructed in this dream, an infinite distance away. Yet its affect was felt still here.

All the time in world was sacrificed. I doubted that I could handle the reality marble for more than a minute now. The Heaven's Feel magic had its duration reduced to less than ten seconds. But it was worth it. Now the time was mine. Better work fast.

[Final Stage]

Fourth Magic: Truth Manifestation

My manifestation of Gilgamesh's Sword of Rupture Ea. A scabbard capable of forcing the Truth on the Universe sheathed the Excalibur. Sheathed it was, yet stronger and deadlier it was now. The Truth that Universe was Chaos once and to Chaos it shall return.

Trace ON: BREAK PHANTASM

Using Heaven's feel, I forced my soul beyond its limit. Knowing that I could finally handle the near infinite prana of Second Magic without my soul tearing apart, I Broke Excalibur.

I could feel my soul ripping apart from the blatant blasphemy I committed and rejoining again due to Heaven's feel, yet I continued. I was beyond pain and thought.

Slowly far above us, the Broken Nobel Phantasm moved towards the dragon but then the Fifth Magic kicked in.

Normally it would take an eternity of time to accelerate something with any mass to the speed of light due to the laws of physics but with the Fifth Magic, time travel was within my domain. I sent Excalibur travelling through an eternity of time.

With a force that belied description, the phantasm stuck the One Born of Dreams.

My reality marble folded upon itself and broke; such was the strength as I slowly floated away into the Dimensional Gap.

I should have stuck to just studying.

Author's Note: So should I continue?

No promises though, medical has been fucking the shit out of me.
