I do not own anything

Sakura, at the age of eight, didn't know what was happening. One minute she was at school and walking home. The next Darkness. Creatures born from the dark, with the world dying, lands lifting into the void in the sky. She saw a giant version of those creature fighting something, but was to panicked to care as she ran to safety, not wanting to be anywhere but her grandfather.

As Sakura ran, she bumped into someone. When Sakura refocused on who she bumped into, the young girl froze as she saw a person with a mask in front of her.

She shivered a bit as the male chuckled at her.

"So this is where that power was coming from."

She tried to make a run for it, but it was hopeless as she was gripped in the wrist by the male's hand.

"Now where do you thing your going, grail?"

She froze upon hearing that before being hoisted up upon the male, Vanitas, shoulder. Seeing that wasn't able to get out of the situation, she gave up as her arms dangled downward, accepting her fate.

This confused Vanitas, thinking she would of put up more of a fight. However, he shrugged as he summoned a Corridor of Darkness.

'Wondering if the old man would even care about this?'

Honestly, he's only doing this because the old man wanted to find this 'grail' upon this world, unknown if this little girl is even that or something else entirely.

'Whatever, this is just one of those stupid experiments of his. He's not even really in it for the long run.'

Just as Vanitas stepped into the corridor and vanish, Archer turned the corner. The last glimpse of seeing a little girl, realizing he didn't make it in time.

'Damn it, i'm to late!'

Archer gritted his teeth, to late at saving the girl that was taken. The servant jumped back as he dogged a punch from the the Heartless creature, Darkside.

As the Counter Guardian pulled out his swords, he wonders what will be the future of this world.

Meanwhile, Vanitas and Sakura appeared upon a world, the Keyblade Graveyard.

Vanitas dropped the girl to the ground. When she landed on her butt. seconds passed as the two stared at eachother. Finally, he spoke in a mocking tone.

"What, no response? You're in a new world, kiddo."

He expected shock, fear, awe, anger, something! Instead... all he got was a blank look.

Vanitas scoffed as he looked at her.

'The hell type of kid is she? It's like she's dead or something.'

With Sakura... she didn't know what to think. World? What did he mean by that? How did they get here specifically? Would grandfather even be able to come here?

Minutes passed, and finally a corridor appeared. Stepping out of it was Master Xehanort, arms beind his back."

"Tch, what took you so long?. I was getting bored already."

The old master chuckled, honestly terrifying Sakura, seeing that his eyes is that of a schemer.

"Apologies, I had to take care of a 'certain' family in order to proceed."

Xehanort turn to the girl who hadn't stand up, making her froze.

"So who is this suppose to be?"

If Vanitas mask was off, his eyes would be rolling,

"Beats me. Her negativitiy was what brought me to her. You weren't discrete on where it was."

"I see."

Xehanort uncrossed his arms from his back, revealing something that had Sakura taken aback, and Vanitas crossing his arms.

"What is that suppose to be?"

"This was from the Einzbern homunculi, Given time, I should uncover it's secrets in order to call upon my own servant."

"What about Eraqus? The Exams not to long for Terra and Aqua before they begin."

Xehanort merrly laughed at that.

"It is but one road for me to take. Trust me, i will make certain our outcome will come to fruition."

Xehanort and Vanitas then turned to Sakura, with her not saying a word since they've spoken.

"Now... what to do with the additional piece?"

Later...

"The situation. How... bad are we talking?"

Ruler, Jeanne d'Arc, never expected the situation to be this bad. Worlds are dying out, Merlin that was far different from the one the grail had gave her, an exhausted twelve year old boy that is somehow a Master with a powrful weapon called a 'Keyblade', and a very powerful servant that has not yet materialized.

And that was just the start!

"His plans, Xehanort, became a reality, two years to early on what was suppose to happen. This was not the timeline that was suppose to happen."

This honestly worried Merlin. Sora shouldn't even be a Master, let alone one of Assassin. It was a surprise when Assasian told him, in his own way, was because he refused Xehanort originally when called upon. So much so, that the grail chose a different Grand Servant for Xehanort.

Merlin than turned to the unmateralized servant.

"Can you please reveal yourself, Servant Assassin?"

When the servant matralized before her Ruler's eyes widen in shock at whom it was.

"Hassan-i-Sabah. Grand servant Assassin. What hast thou accumulated upon thy apperance?"

Surppressing as much of her shock as possible, Ruler turned to Merlin in Confusion.

"Does he not know?"

"I'm afraid the both of them are considered late arrivals. My dear, this would be considered... a 'Universal' Holy Grail War."

Ruler was, to say the least, floored.

"What!? But the boy's only twelve! How are we suppose to put our faith in the hands of a child!?"

Not to say he can't do it, but the situation is absolutely insane from what she is understanding.

"Which is why i requested upon help of one of the Lords that was originally from the Clock Tower, along with myself to fully teach him as well."

Junt in time, one of Merlin's acquaintance showed up.

"Ah, Waver! What impeccable timing. I know exactly who to train the boy with."

Waver sighed as he rubbed the back of his neck.

"Greetings, my name is Waver Velvet. I would like you to refer to me as my title, Lord El-Melliol II"

Hope this wasn't to bad. Sorry if I messed some stuff up.

I think merlin would know sora would be the one to see the future, but thats just me.
