Chapter 1 Artoria of House Pendragon

Artoria was not a happy girl.

She was rich, she was beautiful, she was talented, and she was healthy. She had everything a girl could ever wish for. However, one thing always eluded her.

Artoria of House Pendragon was not by any means, a normal girl. The house Pendragon, once a name of the King of knights, has now fallen. Even though the name of Arthur Pendragon still brings pride to England, his descendants did not.

'Oh, house Pendragon, the noble house who fled England!', people used to ridicule. Artoria knew the truth was different, but it matters not in the eyes of her fellow people.

The house Pendragon has left England when they were at their most vulnerable, and traveled all over to China where her ancestors stayed for a hundred years, and then over the seas to Japan.

Why? The reason was fairly simple.

Artoria sighed as she squinted, mana swirling within her irises. A fiery circle appeared in her sky-blue eyes and the whole world she saw turned into an assembly of crimson lines. 'Lines of Death', her ancestors had named it.

This was the very reason for house Pendragon's dishonorable retreat from England. At that time, it was said her ancestors had no knowledge of their mystic eyes, and many have died trying to harness this terrifying power.

The mystic eyes of Death perception, the power that opens up a circuit in the eyes to 'perceive death'( the conceptual 'Death of an Existence') as visual signals in the form of 'lines'. If cut against the 'lines', it will result in immediate death.

They show the death of things, the weak points where everything is most easily broken and the imperfection in everything that will eventually break down one day.

Rather than "seeing," it is more like they were "observing" everything at a higher level. "Death" is invisible to normal people, only accessed through perceiving the natural flaws with an overly strong spiritual sight.

This was the power that plagued house Pendragon shortly after the fall of King Uther. This was also the reason that they left two young children of their family behind; Arthur Pendragon and Morgan.

These two were the only ones who weren't afflicted by this horrid mutation. The family thought it to be too dangerous for them to stay in England, thus, they left the country with the two behind.

Over the centuries, the Pendragons has become quite acquainted with the blade arts of ancient China and the prominent katana skills of medieval Japan. The Pendragons developed a sword art best suited to their mystic eyes, which made them unstoppable in battle.

Artoria Pendragon herself was very skilled in the way of the katana, mixed with Chinese martial techniques. She personally preferred mana bursts for acceleration, but always ended up winding herself up at the worst moments.

She sighed once more, fiddling the heart-shaped ruby absentmindedly between her fingers. Here she is now, the only heir to house Pendragon. Artoria Pendragon, the last of her kind.

The ruby was sent from Zelretch of the Clocktower, along with a top-secret mission from the headmaster herself. The Clocktower was one of the main sources of income and patron of the 'runaway' Pendragon family. In other words, not a client she could turn down.

Artoria was already more than enough stressed because of the mission, but Zelretch just had to jam in his ugly head. Zelretch, the grand magician. Zelretch, he who shot down the pale-blood moon. Zelretch, he who traversed the worlds.

A headache started to brew in her head as she thought about her mission. 'Win the Holy Grail for the Clocktower', the letter had said. There was no way she could actually decline, thus making matters worse. 'Orders are orders', she thought mournfully.

She rubbed her temples as she pondered harder on the reason why Zelretch sent her a ruby of all things. She was also desperate to find out why the holy grail had chosen her in the first place.

Artoria rubbed the back of her right hand in frail hope that the red mark could be scrubbed away. It didn't do anything. It seems that the stubborn marks just refused to leave her in peace.

She glared at the vivid marks, the cause of her splitting headaches. Three intertwined seals formed into a sword. The command seals of the holy grail.

The clock let forth a loud gong. The time was near. It was already midnight, only a few minutes before she should start her summoning. Artoria nervously bit her lip as she checked her catalyst for the hundredth time.

The shard of the divine katana 'Tsumukari Muramasa (都牟刈村正)', check. The summoning circles, check. Intricate mana control, check.

Breathe in, breathe out. Artoria nodded to herself, a grim smile set on her face. She was ready.

Somewhere Far Away. Another plain of reality

Zelretch of the Kaleidoscope opened his weary eyes. It took a toll to extract certain objects from parallel worlds, even for an immortal wizard like him.

A low humming sound filled the empty void where he sat. "About time.", he muttered as he tapped his iron throne.

"Alaya."

The manifestation of humanity's will appeared in the dark space; a brilliant orb of blue surrounded by pulsing rings of pure light.

"Zelretch.", it stated.

"Why did you pass the catalyst of Counter-force EMIYA to Artoria Pendragon of world No.0000004?"

Zelretch grinned shamelessly. He quirked an eyebrow towards the great System of his planet with an exasperated shrug.

"Surely, you do know this holy grail war would turn out to be a colossal mess?"

"It matters not. This world shall be cut off soon enough."

Zelretch smirked. An innocent smile danced on his lips as he asked the question he was waiting for.

"Then why did you even bother?"

Alaya went silent. Zelretch saw his chance and continued.

"This world must affect the 'tree of worlds' in some way. I'm just making sure it survives."

"Do you plan on converging the data of EMIYA with Sengo Muramasa?"

"It is absolutely possible if you consider how similar they are in certain ways. They might as well stemmed from the same bloodline."

"…Very well. Proceed as you wish."

Alaya dissipated into thin air, leaving Zelretch alone with his own thoughts.

"Alaya, old friend.", he chuckled ominously. "This shall be one hell of a war."

In the storage house of Pendragon manor.

"Fill. Fill. Fill. Fill. Fill. Let each be turned over five times, simply breaking asunder the fulfilled time."

"Let silver and steel be the essence.

Let stone and the archduke of contracts be the foundation.

Let my great master Uther Pendragon be the ancestor.

Raise a wall, against the wind that shall fall.

Close the four cardinal gates.

Cometh from the crown.

Rotate the three-branched road reaching the Kingdom."

"– I shall declare here. Your body shall serve under me. My fate shall be with your sword.

Submit to the beckoning of the Holy Grail.

If you will submit to this will and this reason… then answer!"

"– An oath shall be sworn here! I shall attain all virtues of all of Heaven. I shall have dominion over all evils of all of Hell!"

"– From the Seventh Heaven, attended to by three great words of power, come forth from the ring of restraint, O'Protector of Balance!"

Instinctively, Artoria raised a hand over her eyes at the blinding white light that pierced the darkness. Gales of unnatural wind blew wildly in the small storage, ripping the door off its hinges in its rage.

After a long minute of enduring the ferocious storm, silence returned. The winds settled, now nothing more but a light breeze. Artoria sat down, too stupefied at the sight before her.

There he stood, her servant of war. And what a magnificent sight it was for her to behold!

Red wavy hair that ruffled in the cool night air. A piercing gaze of hot iron that grasps one's soul. Hands that shall beat iron and craft legends. From beyond the hazy mist, a young man stepped into the pale moonlight.

He was a tall man, adorned in crimson samurai light-armor with skin-tight stygian leather on his upper body. Wrapped around his shoulders was an elegant kimono that billowed behind him in arcane energy.

The man cracked his neck, an amused smile tugging his lips as a fleeting gleam of recognition flickered past his warm eyes.

"Ah, I see. So this is what became of this timeline. I never knew it was even remotely possible to attain synchronization with another.", the man whispered to himself.

"Huh?", Artoria couldn't help but ask. What did he mean by that?

The man laughed, scratching his head sheepishly.

"Never mind what I just said. Well, let's get started with this 'tradition', shall we?"

Before she could even ask what on earth he was talking about, his friendly smile disappeared. Artoria gulped.

The temperature seemed to rise from the burning heat he was radiating. Absolute seriousness took its place.

"I ask of you. Are you my master?"

If you have any ideas, please let me know!

X-kalibuuuur, over and out!
