I own neither Arknights nor Fate/Stay night
Three Years before Artoria pulled the sword from the stone
In the castle of Sir Ector courtyard two children were playing a mock fight with a wooden swords, both of them were around the age of 12.
A boy with normal complexion ash grey hair, blue eyes, he was wearing a black tunic, a pair of brown leather pants, a pair of boots.
And his opponent was a girlish looking boy with blond hair tied in a ponytail, wearing a white tunic, trousers and a pair of boots.
"Is that the best you can do, Arthur?" The Boy said as he parried Arthur's strike.
"I've have yet to yield Dearil." Arthur replied as she moved to strike.
Above the courtyard to men were looking at the kids little display of swordsmanship.
"Your foster kid, sure has picked up the sword rather neatly, hasn't she." Said a man that was next to Sir Ector.
"I'd say the same Kenway." Replied Ector.
Ector was a man that stood at 5' 10" he had brown hair and eyes, he was wearing a white colored tunic with black lining, a pair of brown trousers, and boots.
Kenway much like Dearil, had ash grey hair, though he had amber colored eyes and stood at a much taller height of 6' 6" which was rather uncommon for a person to be this tall.
"Have you heard the news?" Ector asked Kenway.
"What news?" Kenway asked Ector.
"The mage came yesterday, he informed me that Vortigern has usurped the throne with the help of the Saxons." Ector told Kenway.
"And what has that mage cooked up in his mind?" Kenway asked.
"He plans to make Arthur the new king, as far as Merlin told me Vortigern has drank to the blood of Albion and he informed me that only Arthur is the one to truly be able to kill him for good and..." As Ector informed Kenway, the man was interrupted by the latter.
"He's dropping all that responsibility on the shoulders of a child?! Is he insane, does he have any idea how damaging it would to that kid?!" Kenway asked as he pointed at Arthur.
"That's what I told the Mage, but..." Ector said as he began to trail off.
"But what?" Kenway asked Ector.
"But, according to Merlin, there is another person that is able to slay Vortigern." At that Kenway froze, and looked at Ector with a look.
"No, I will not have my son die just so he can kill a tyrant, and I will not have the Lord of Fiends let loose on the land." Kenway told Ector with a firm tone.
Ector let out a sigh he knew Kenway would never put such a curse unto his son, after all the Lord of Fiends would have been far worse than Vortigern in the long run.
"Then what will you have us do?" Ector asked Kenway.
"I cannot say for certain not can I do anything about it, but I will say this, to force a child to become King is nothing but a crime that will lead to further chaos in the future." Kenway told Ector, who simply let out a sigh.
"I agree with you my friend." Ector Said as he returned his attention to Dearil and Arthur, who were playing with Kay who had returned from a hunting trip with his entourage.
12 Years later
Dearil, now the lord of his lands, stood in front of the official coronation of Artoria, who was wearing her armor, which covered her legs, torso and arms.
Dearil stood as tall as his father at 6' 5" his armor consisted of shin guards, armor plates that covered his shoulders, arms, Torso and underneath a mail shirt, and the helmet resting on his arm.
"So, what do you think of these new events Lord Dearil?" Came a female voice, making Dearil turn and look at a blond woman with long hair, emerald green eyes like Artoria.
She was wearing a black dress with turquoise linings.
This was Morgan, Artoria's Half sister from the Union of Uther and Igraine.
"What is it, Morgan?" Asked Dearil as he looked at the Woman with a cold gaze.
"Come now dear Dearil, do you think that I don't know about your infatuation with my sister?" Morgan told Dearil who simply looked at her with a dulled look.
"And what of it?" Asked Dearil.
"You know... That my step father and Merlin planned for Arturia to take the throne from the very beginning?" Morgan told Dearil.
"That is obvious, since the mage seems to have a satisfied look to his face." Dearil commented.
"Did you also know that when Artoria pulled the sword from the stone it cursed her?" Morgan asked Dearil, making the lord to turn and look at the woman with a narrowed gaze.
"What curse?" Asked Dearil in a low tone.
"Well... Merlin did warn my dear younger sister that if she were to pull Caliburn from the stone, she would be hailed as the rightful sovereign of all Britain, however..." Morgan said as a barely noticeable smirk appeared on her lips.
"However..." Dearil said in a demanding tone.
"However she would loose the ability to feel any sort of human emotion. And my foolish sister thought that was an advantage rather an hinderance." Morgan said in a gloating tone as she let out an amused chuckle.
And Dearil stood there and soon enough he realized the implication that this statement had for the future of the realm they had forged through their wear against Vortigern.
"This would lead to a rebellion against Artoria in the future..." Dearil said with realization in his voice.
"So what will you do, O' Lord of Fiends?" Morgan said in amusement in her tone, making Dearil look at her with an angry look.
"Don't even speak of that." Dearil said with a threatening tone.
"Or what? Will you come and ravage me, O' lord of fiends?" Morgan asked with an amused voice.
"Is there a Problem?" Came a soft female voice making Morgan and Dearil to turn to their right and see a woman about 3 years Dearil's junior wearing a Red dress, She stood at 5' 5" and had a lithe body build, a pale complexion, amber eyes.
And the dreary mood made a whole 180.
"Hello Royse." Said Dearil as he walked up to sister and gave her a deep hug.
"What were you and Morgan talking about?" Royse asked her brother, while Morgan wave at her.
"Nothing of importance Sister, now come I think it's for us to retune to our home." Dearil said as he walked passed her.
"Alright." Said Royse as she followed after her brother.
"Let's see what will you do now O' Lord." Morgan said as she simply chuckled.
6 months later
In a lake in the middle of a forest Dearil sat, he wore nothing but a tunic, trousers, and boots and a sword that that rested next to him, and he was waiting for someone.
"Dearil?" Came a feminine voice, making Dearil to turn and look behind him to see Artoria wearing a white tunic trousers and boots and Caliburn.
"Hello Artoria." Dearil said as he got up. to greet his long time friend.
"Why did you call me here Dearil?" Artoria asked him, and Dearil only flashed a melancholic smile.
"For old times sake, and besides you must really bored cooped up in that castle of yours." Dearil joked.
And Artoria seemed less than amused.
"Just get to the point Dearil as I know for a fact that you are not a person to waste time on making jokes like Kay." Artoria told Dearil with a less than amused look on her face.
As for Dearil? The man let out a sigh, scratched his head, gave the lake a quick glance and turned his attention back to Artoria.
"Fine... I've been wanting to tell you this since we were 15 before you picked the Caliburn off of the stone that..." Dearil said but he trailed off not able to properly finding the words he wants to tell her.
"Yes?" Artoria asked as she crossed her arms waiting for Dearil's response.
The Man took a deep breath and looked at Artoria square in the eyes.
"I Love you."
3 Years later northern Norway.
Dearil had left the Isles, because he couldn't bare anymore the stifle sense that brought him every-time he overlooked his realm, or when attending meetings with Artoria at Camelot, so he left and left the administration of his realm to his sister, a person whom he trusted deeply but also to get away from the feud that was brewing between Morgan and Artoria.
Though he did bring an entourage of 10 men who were akin to the knights of the round table in terms of skill, but they had none of their blessings.
They weren't Gawain with his great stature and strength.
They weren't Tristan with his unmatched skill with his bow.
They weren't Lancelot and his skill's with the blade.
Nor were they like Mordred with his ferocious strength.
No they weren't like the knights of the Round Table, but their loyalty was matched only by Bedivere's own to Artoria, though they may even surpass that.
They were his blades, they followed his order's to the letter, and would die to follow through those orders.
Each of those men were dressed in black armor with red lining and a side cape.
"My lord there is something on the horizon." Said one of the men as he pointed at some thing protruding onto the sky.
"Take us closer." Dearil ordered.
"Understood Sir." The man complied as he relayed the order.
"So why did you call me all the way to the north, Dearil?" Asked Morgan who was wearing winter clothing.
In front of her Dearil was standing in front of her with an empty look.
"I didn't call you here for socializing Morgan, I am in need you services." Dearil told the blond woman who simply raised an elegant eyebrow.
"Oh? And what do you need?" Asked Morgan.
"I need to bind fragments of several Demons from a different Dimension to each of my Men." Dearil told Morgan who simply chuckled.
"You are aware that you are trudging dangerous grounds Dearil." Morgan told Dearil.
"I know, and if means to free Artoria from her curse then it is something that I am willing to take, after all a saint must always face against a demon, besides I heard Mordred has been cooking up a rebellion." Dearil said as he walked up to Morgan.
"And besides, they will is unbreaking, the demons will not take a hold of them." Dearil told the Witch.
"Whatever you say." Morgan told Dearil.
Centuries later
Camelot Singularity
"You have what is necessary that will assist you, on your journey to the holy city." A man with tanned skin black hair and golden eyes said as he sat on his throne with him leaning on his arm.
"Thank you Lord Ozymandias." A boy who was flanked by a girl with lavender colored hair, and purple eyes, said as he bowed before the king in front of him.
"Though if things go awry, go North and request the help of the Lord of Fiends, I heard he has a feud with the Lion king." Ozymandias said.
"The Lord of Fiends?" Fujimaru asked.
"Indeed, though to be careful his Personal Enforcers are said to be more than a match for the knights of the round table, and it required both Mordred and Lancelot to defeat just one of them." Ozymandias as a smirk appeared on his face recalling that encounter.
"Your warning is appreciated." Fujimaru said as he again bowed before the god-king.
"And before you leave, one more warning, the Emperor's blade are the will of the Lord of Fiends and wherever they go it is their territory and that their lord." Ozymandias gave his final order.
At a distance of the palace a covered by snow and frost a single armored figure could be seen, he was wearing heavy armor and his visor glowed red.
"So these are that is the last master of Humanity that my lord told us about? Hmh his peerless foresight was true as always, they do appear to be an interesting bunch, now let's see how far they go." The man said to himself as he walked back to his lord waiting to be informed of the arrival of the last master of humanity.
