Fate/Grand Blunder: A Fate Multicrossover

Chapter 1: Welcome to Chaldea

"I, Servant Saber, have come in response to your summons. I ask you; Are you my Master?"

The 48th Master of Chaldea, Ritsuka Fujimaru, greeted the newest Servant with a smile on his face. Flanking his right was Mashu Kyrielight, the bespectacled Shielder Class Demi-Servant. To his left was the venerable Renaissance Man Leonardo Da Vinci, Servant Caster, who was inexplicably summoned as a brown haired woman clad in blue and red, the resemblance to his finest work, the "Mona Lisa" not lost to them. The one who stood before them on the Summoning Circle was a face recognized by many. The blonde hair, blue dress, and the polished silver armor served only to give the girl an air of royalty. The clear green eyes showed resolution and drive. She stood tall despite her short stature, showing the confidence one required to be king.

Of course, all this is to be expected of Artoria Pendragon, known far and wide as King Arthur of Camelot.

"I am." The young Master nodded as he offered his hand with a smile. "Welcome to Chaldea."

"Chaldea...I see." Artoria nodded. She had been summoned with the knowledge of current events thanks to the FATE System. Thanks to that, she knew what Chaldea, known formally as the Chaldea Security Organization, was and the current state of the world, as well as the Grail Wars she had taken part of up to now. Notably, she knew how the entire place had been cut off from the world due to current events. "So it has become dire, has it not?"

"I'm afraid it has." The Master sighed with a rueful smile. "At any rate, I look forward to working with you."

"Indeed. As do I, Master." The Saber responded with a smile as she took the hand he offered as a sign of friendship.

"By the way, you can call me by my given name, Ritsuka." The Master replied before gesturing to the girl next to him. "And this is Mashu Kyrielight, Servant Shielder. Also, this is Leonardo Da Vinci, Servant Caster."

"Nice to meet you." The lavender-haired girl with spectacles bowed politely.

"Likewise." The Saber nodded back with a smile. "Now, if we may be able to discuss our current situation..."

"Ritsuka! Is that the new Servant-!" Artoria turned to see that a new arrival had entered the Summoning Platform. Said new arrival stopped in her tracks upon sighting the King of Knights. She was a girl of short stature and wore her blonde hair in twin pigtails and had light green eyes. She also wore a black trenchcoat over a white blouse and a red-and-black plaid skirt that complemented her slim frame. Her black-and-white boots and white gloves topped it all off perfectly.

Artoria herself felt her eyes widen at the sight: She remembered this girl from a version of the 4th Holy Grail War she participated in. She knew her a staunch ally and was one person she was glad to see again.

"Maka Albarn. Servant Berserker." The blonde knight smiled warmly. "It's so nice to see you again, my friend."

"The feeling is mutual." The Scythe Meister responded with equal joy, walking over to take her hands in hers. "I was beginning to wonder when you'd show up."

"I certainly wasn't expecting to see you at any rate." Artoria replied. "What about Soul? Is he here as well?"

"He's lounging about somewhere, but we'll be seeing him soon at any rate." It was at this point Maka then turned to see the fond smile Ritsuka had on his face.

"You two know each other?"

"It's a long story." The Berserker let out a small giggle.

"You can tell it along the way." Ritsuka answered with a smile. "Now, without further ado, let's get this tour started."

"I see...So you two have met in a Grail War before?"

"More or less." Artoria nodded as she and Maka explained how they met to her new Master. "Our Masters formed an alliance and we became fast friends, even if we fought each other in the end."

"That actually sounds like a touching story." Ritsuka chuckled. "So I take it you had Irregular Servants in your War too?"

"Irregular Servants?" The Saber asked with a raised brow.

"They began to show up around the time we finished the Third Singularity." Mashu explained as they walked through the spacious hallways of the complex. "Not only were names of Heroes we were not familiar with begin to show up in the database, but versions of them that had radical re-imaginings began making an appearance as well. It took some digging up, but we eventually found out that these Heroes are products of later works of fiction, mostly around this century."

"Movies, Video Games, TV Shows and other sources of media." Ritsuka continued. "These Heroes were added to the database for reasons not known even to Director Archaman, who you'll be meeting along the way."

"If he is not slacking off as usual." Da Vinci sighed "Still, how they all showed up in the FATE System is beyond even me. I have some theories about how it came about, but that would take a lot of time to get over."

"I could listen to you drone all day, lovely Da Vinci." The Renaissance Woman rolled her eyes as the source of the flirt entered the scene. The tanned skin man had a lean frame adorned by a simple gold colored robe that covered a white dress shirt. The decadent attire did very little to hide his lean build, and one cannot deny that he had a certain charm about him, a magnetism that both women and men cannot help but find appealing.

"I do hope that you remember that, though I was summoned as a woman, I'm still very much a man." Da Vinci sighed at the new arrival.

"That has not stopped me before." The man chuckled before turning to the new arrivals, taking especial notice of Artoria. "Ah, so we have a new comrade with us! I am Oberyn Martell, the Red Viper of Dorne and Servant Lancer. Pleased to make your acquaintance."

"A pleasure to meet you as well, though I have not heard of your legend before until now." Artoria nodded with a brow raised.

"He's an Irregular, like myself. Anyway, This is Artoria Pendragon, Servant Saber and a friend of mine in a Grail War I fought." Maka sighed. "Please behave yourself around her, Oberyn."

"Your words wound me, Lady Maka! I'm the picture of perfect behavior!" The Lancer chuckled. "Though I will not deny that our newest Saber is quite the flower!"

"While your words are indeed flattering, Sir Oberyn..." The Saber felt her brow twitch. "I feel that I must inform you that I am a knight first."

"A shame." Oberyn couldn't help but chuckle. "Nevertheless, I look forward to seeing what you can do in the battlefield, Lady Artoria."

GRRRRRRRR!

Before anyone could say anything, a loud rumble was heard. They all turned towards Artoria, blushing heavily due to the fact that it was she who was the source.

"Well, I suppose it's about time for lunch anyway." Ritsuka laughed. "How about we get a quick bite to eat?"

"My word..."

Artoria found herself amazed at the sheer size of the cafeteria. It's marble white interior as well as the rows of rectangular lunch tables did well to add to it's ambiance. As lunch time was almost over, the place was largely unoccupied save for a few Servants and personnel scurrying, some hastily finishing their meals before they return to active duty.

"Pretty big, isn't it?" Maka asked her with a chuckle. "It overwhelmed the first time I saw this too." She paused to scan the thinning crowd for her Partner. "Anyway, let's go find Soul and-"

"There you are, Maka." A spiky haired lad with shark-like teeth clad in a black blaze over a white shirt and jeans walked towards them with a grin. He acknowledged Ritsuka, Mashu and Oberyn with a nod before finally noticing the new arrival. "So, you've finally come to Chaldea. Been wondering when you'd show up."

"'Tis good to see you as well, Soul." Artoria simply nodded with a smile. "I never believed I would run into two old friends of mine in a place like this."

"My, how cold of you to say that." All turned to see yet another approach them. She was clad in a dark blue sweater over a white halter top, capris and stilettos. Her platinum blonde hair, usually kept in a prim and proper bun when in her battle regalia, was down so it flowed freely like a river. Her deep blue eyes twinkled and her fair features formed into a smile. "Why, I thought you and I were friends as well."

Seeing the Saber stare wide-eyed, the Master could only chuckle. "You two know each other as well?"

"A different Grail War, but yes." Artoria nodded. "She was the Servant Lancer, but I came to rely on her as a friend." She recovered and bowed with a smile. "It's good to see you again, Gwendolyn Odinsdottir."

"Likewise, Artoria Pendragon." Gwendolyn smiled back at her friend.

"And yet another flower graces us." Oberyn chuckled. "Perhaps you and I can enjoy ourselves in a night filled with fine wine, Lady Gwendolyn?"

"The thought is tempting, Lord Oberyn." Odin's Witch shook her head with a sad smile. "Alas, my heart belongs to another. Even now, I await the day he arrives at Chaldea's gates."

"Such devotion is worthy of respect, for certain." the Viper chuckled. "He must be quite the man if you are smitten so."

"Indeed he is." Gwen responded, this time with fonder smile.

"How about we go get that bite to eat?" Ritsuka interjected. "Our newest Servant's pretty hungry at this point."

"Ah of course." Gwen giggled as she motioned to one of the empty tables. "I suggest you all get your trays and not keep our assigned chef waiting."

Artoria wasted no time in making for the the lunch line with tray in hand. Awaiting among the appetizers was a girl with long blonde hair, green eyes and a slim figure dressed in a lunch lady uniform.

"Welcome and help yourself to the-Saber?!" The young girl blinked in surprise upon seeing the King of Knights at the lunch line. "Y-You're here?!"

"Indeed I am." Artoria recognized her as well, smiling fondly as she remembered at least two Grail Wars where the girl before her was a Servant. "I see that your here as well, Archer...or was it Slayer?"

"Oh right, I never told you my identity." The lunch girl giggled. "Lt. Noel Vermillion of the Novis Orbis Librarium, at your service!"

"Did you cook all this?" Artoria asked just as the others behind her paled in horror.

"Sadly, no." Noel sighed, causing the others to breathe out a sigh of relief. "The Director never let me cook again after that one time."

"Can't blame him when a good number of our staff and Servants went down with a severe case of food poisoning right before a Singularity." Mashu interjected, causing Noel to frown.

"That girl's cooking is more potent than any poison I can concoct." Oberyn muttered under his breath.

"I'm surprised it's not a Noble Phantasm we don't know about." Soul whispered back.

"Which is why she's under my supervision whenever she's in the kitchen." Another figure emerged from the back. He was a stalwart male wearing an apron over a black dress shirt and black slacks. He had tanned skin, white hair that was slicked back, and gray eyes that did little to hide the heart of steel beneath. Maka, Noel and Gwendolyn knew him from a Grail War, but it was Artoria who had the most poignant connection with him; In many a timeline, he would appear as the future incarnation of her Master in the 5th Grail War.

"EMIYA?" The King of Knights asked in a soft tone.

"Good to see you too, Saber." The Hero of Wrought Iron chuckled. "I didn't believe we'd run into each other so soon."

"Neither have I."

"Anyway, I won't keep you any longer." EMIYA sighed as he turned to go back to kitchen. "I'll speak to you after the tour is over."

Everyone looked on as Artoria watched the man leave. Maka, Gwen, Soul and Noel in particular with warm smiles on their faces. Ritsuka, being as clueless as Mashu, Da Vinci and Oberyn were at the moment, decided to ask.

"Did you know him?"

"...Yes." Artoria turned back with a smile. "It's a long story to tell, for certain. One that can be told over a hearty meal and in the company of friends."

"Sounds about right." Maka nodded with a smile.

"My shift's almost over anyway, so I'll come and join you guys soon!" Noel added with a smile.

"I would like that." Artoria smiled as she and the rest got their lunch and walked over to their table. As she feasted and watched the others chat among themselves. She reflected upon the situation she found herself in; It was unfamiliar in the sense that this would be the first time she fought not for her own wish. Still, the memories she had of the lessons she had learned in the past Wars told her that she needn't shoulder the burden by herself. If anything, Chaldea was proving to be quite interesting.

"Yes." Artoria smiled fondly as she watched Maka conk Oberyn in the head with her signature hardbound book after he made an inappropriate comment. "I think I would love it here."

END

A/N: Ladies and Gentlemen, I'm the King of Beasts and welcome to the first chapter of Fate/Grand Blunder!

If you're all wondering what this is, it's basically an experiment that tries to answer what would happen if those Servants from Alternate Grail Wars (The Infamous Man's Fate/Zero Sense, CleverPervertedPriest's Fate/ Level Zero, X the Reaper's Fate/Zero Sanity series) somehow made it to Chaldea. Speaking of the latter two, I have their approval to use the Servants they used in their respective fanfics in this series of one shots inspired by GhostXavier's Fragments of Chaldea. Seeing as that's pretty much the definitive Fate/Grand Order fic (for me, anyway), I recommend it as a captivating read!

Now, I'll be following some of the rules GhostXavier made for FoC with my own twisted into is. Such as:

1. Saber (Artoria) will remember every alternate Grail War she's been in (I.E Fate/Zero Sanity and Fate/Level Zero).

2. The same rule applies to canon Servants who appeared in those fics (I.E Gilgamesh, EMIYA, ETC.)

3. If a Servant has been featured in two or more alternate Grail Wars, they will remember both Wars as well.

Why did I say two or more, you ask? Well, if you guys have a Servant recommendation or an alternate Grail War fic's roster, I would love to feature it here as well! Just hit me up with a PM and I'll give it a look! :D

Welp, that's all from me so far. Please leave a review to tell me what you thought of this. I am the King of Beasts, and I'll see you next chapter!
