AN:I started writing this shortly after I posted the prologue and it has taken me most of the day to finish it while also attending college classes. In that time I received several reviews for the prologue. And even a few follows. I'd like to thank you guys for the support especially since this is my first fic. Chapter 1 is much longer than the prologue was. Some people voiced concerned that the prologue felt too similar to many other FSN crossovers out there. And between Zelretch and Angra Mainyu both being used the for crossover and plot establishment I think it does too. I just hope that the first real chapter where we start to get characters and servants and fights going that it will seem better.

Story Start

Rin Tohsaka could not fail. Everything was perfect for her summoning, the circle had had ample time to absorb the the latent prana in the air, she had waited, and knew that now there were only two servants left to be summoned, Archer and Saber. She would not use a catalyst, instead allowing the Grail to choose the Servant best suited for her, one with whom she would win the Grail in the Tohsaka name. She would summon Saber the most powerful of all servants. It was time, she retrieved a blood rem jem from her pockets. Power radiated off of the stone. It was filled to the brim with prana aching to be used. A family treasure, crafted by her Father before his untimely death in the last Grail War.

"I command thee...

Thou shalt come forth to my side;

Thy sword shalt control my fate."

This was it. The circle had begun to glow. It would create a vessel for a Heroic Spirit to inhabit. It would not be the true Spirit, merely a copy of one pulled from the Throne of Heroes within the Akashic records. But even still their strength would exceed any seen in modern times. Legends with the skill and strength to stand against armies and monsters and not only fight but win. A Heroic Spirit. A weapon. Her weapon with which she would best her foes.

"Abiding by the Holy Grail's haven,

If thou accedest to this will and reason, then answer me

The oath set forth here.

I am the embodiment of good in the eternal world.

I am the disposer of evil in the eternal world.

Thee, the seven heavens that bear the great trinity,

Come forth from the circle of constraint..."

The Servant she summoned would be a legendary hero, most likely from the forgotten Age of Gods. When the very air was laced with mana and spells the like of which may never be seen again outside of the five true magics and the Caster Servants of the Grail War. Her Servant would be powerful skilled and they would be partners against all the enemies they would face in this war.

"... O Guardian of the balance!"

The light radiating off of the summoning circle was getting unbearable for the magus, and just when she thought she'd have to squeeze her eyes shut and wait for it to end the was a gust of wind and then she was truly surprised.

"Ne, ne, looks like I've got an interesting Master nya~"

It was a young girl, shorter than Rin herself by a few inches. She had dirty blonde hair concealed under a brown hooded cloak. Her mischievous green eyes matched the forest green tight outfit hidden beneath the cloak, glimpses caught as she moved her arms around and out of the cloak where they rested. The most prominent feature however was her strange facepaint, three lines parallel to each other on both sides of her face. Almost like whiskers. And Rin was gawking, at the young girl who should be a famous and renowned warrior whose name echoed through history. Such was not appropriate attitude for the Tohsaka heir. Mentally shaking herself out of her shock Rin replied to the Heroic Spirit.

"That is correct I have called you forth to fight in the Holy Grail War. I am Rin Tohsaka, heir to the Tohsaka line. I ask, what class are you and what is your true name so I may get an idea of your strengths and begin formulating plans?" That should be a fine introduction and now that she had calmed herself it was easy to rationalize her Servant's young appearance. Many a hero died young their myths harsh tales, it was rarer for a Heroic Spirit to have white or gray hair than anything else, simply because they died long before the color could fade.

"Ah I liked Rin-tan better when she looked all shocked with her jaw hanging." Apparently the magus needn't worry about saving face with her knew found servant, she had none left to save. "Either way I am Servant Archer, Argo The Rat." Damn, so not only did she summon a little girl but she wasn't even Saber. The name Argo didn't ring any bells so she'd have to spend time researching in the study. Perhaps her Servant Archer would give her some clues where to start.

"I have not heard of your legend before Archer. Could you give me a better idea of your skills? Something is stopping me from seeing your status." At this Archer seemed to light up. She straightened her back, placed her hands on her his and jutted out her elbows. Attempting to make her diminutive figure seem larger.

"O'course ya can't see my status! I'm the best Information Broker in all of Aincrad! I don't need to be Assassin to have Presence Concealment." Her once prideful and full smile turned lopsided and cocky, one eyebrow raising while the other lowered in challenge to one not even present. "In fact I'd bet five hundred col I've got a higher Presence Concealment than This war's Assassin." Rin blinked. The magus had not expected that. She had been prepared for many things from a faulty summon to Archer's Noble Phantasm being the cause. But she did not expect Presence Concealment of a high enough level to outright block even the masters attempts to view their servant. That could be useful. An Archer that could hide made the perfect sniper. If everything went right they could kill enemy servants from far enough away their enemies couldn't retaliate or even find the threat. And if not it made surprise attacks and escapes all the easier.

"We can use that. We'll have to scout of sniping positions across the city but I suppose that would fall under your classes specialties." Archer blinked at this a blank look replacing the grin of confidence that came before. Several more blinks followed the first till a look of realization dawned upon her Servant her eyes went wide and she placed one fist into the other palm.

"No no no, Rin-tan, I don't have a bow." What? An Archer without a bow. I mean it was conceivable. It had happened before but, the way Archer said that seemed to imply...

"Archer. If you do not have a bow then what ranged options do you have?" It would be simple enough to alter the plans for a musket or cannon perhaps. The gunpowder fueled weapons would have more punch but they'd ruin the Presence Concealment with the noise as they discharged, allowing for only one shot before they needed to relocate. At this Archer seemed to get a little nervous. Her arms back in the folds of her cloak and face sinking into the shadows but her green eyes glinted out from underneath staring slightly up. There was a quick mumble to low and fast for the magus to catch. "What was that Archer? Speak louder we need to start forming combat plans." A bit louder this time the Tohsaka could almost catch it. "Yes? What ranged weapons do you have Archer?" There she winced slightly at the title.

"Throwing picks." Came the guilty admission. And Rin's world spun.

"Throwing picks." She repeated out of shock, left hand to her forehead and right reaching out for balance as she fell deeper and deeper into shock.

"Throwing picks." came the confirmation, the mousy girl with one hand out rubbing the back of her head as she held a forced grin, hoping to appease her new master.

"The Heroic Spirit of the bow. A paragon of ranged combat. Legendary warriors who define the world of archery to this day. And I get the one who plays darts!? Why couldn't I get Saber instead? Why did I wait until there were only two classes left to be called" Rin was getting woozy. How could she summon such a Servant? How did Argo even qualify to be an Archer?

"I don't know what to say. I don't get to pick the class I'm summoned as. It must be because of the catalyst you used. Since there were so few classes left to pick from when it called me forth it must have gone with whatever I was closest to and since I'm not a knight and I don't have any swords Saber was even further off base."

"But I didn't use a catalyst!" Rin knew there was no catalyst. She chose to rely on the grail granting her a servant more closely matched to her rather than guaranteeing a powerful servant that she may not be able to control.

At this Argos eyes rose back out of the hood along with the rest of her face. "You didn't use a catalyst? There is always a catalyst, if you don't provide one then the Grail will find a new catalyst. It's just that sometimes that catalyst is the person themselves, some aspect of their character or their bloodline." Here, Rin fell further into despair. Of course the strangeness of her Servant was her fault. All her spells, the work of genius up till the one minute failing in the end. The summoning was perfect she probably could've gone grave robbing. Japan has a rich history of Samurai and Ronin. At least an Archer from their ranks would actually carry a bow. And who had she summoned anyway? The name Argo held no relevance to her, though apparently she is something of a rogue, understandable if she would be harder to find then. Without even realizing it she was on her hands and knees face staring at the stone cold floor despair kicking in. How would she win the Grail War now? A hand grabbed her shoulder and she looked up right into those emerald eyes. The hand was small but strong sure and the eyes held steel and confidence in them. With the last dimming blue lights from the summoning circle back lighting her, Argo, no, her Servant, Archer, looked strong, reliable. "C'mon Rin-tan. I may be Archer but I still have the skills to play Assassin were not out of this as long as you got those seals on your hand." Her grin was strong and sure, and Rin was left wondering if perhaps the Grail did choose the right servant for her.

The normal spot for Archers are the rooftops. High, the altitude would increase the range of their weapons and allow for a larger field of view thus allowing them to more effectively search out enemies. Despite her class title though Argo was not an archer. She was a Rat and rats stayed in allies. Argo was right at home in the dim moist backstreets, used to such places more at home here than in Rin's large estate. Rin, however, was not enjoying the cramped spaces, the sneaking about, the smell or just about any of it. Though, to her credit she raised not a peep in protest. Understanding that her Servant was strongest in these environs and that to win the war. Open areas and nice smells were the least she'd have to give up. Barely above a whisper Argo spoke, "I can sense a Servant, they should be over by the school I believe it's Lancer, there another too, deep in the forest is they must have a low level presence concealment because I can't make out a class. The rest of the Servants must not be materializing much, I'd have sensed them if they were." Rin had decided that despite how useful Presence Concealment was it was Presence Detection that would allow them to go on the offensive tonight.

Rin gave Archer's information a moment's thought. There was an old Einzbern castle out in the woods. The Servant out there must be theirs, and with all the bounded fields on the castle. It was best not to go on the offensive over there. Lancer though. "It sounds like a trap."

Argo gave a sigh. "Yeah I thought so, but if we're going to make a move the trap is better than those bounded fields. I could try to sneak past them but if I fail they'll know to expect it, we won't be able to try again. I'd rather save that move for later on in the war."

Archer's Master nodded in agreement. "Yes, and as long as we know that Lancer is a trap then we can be cautious and retreat if things turn south. The odds of lancer having an allied Servant this early is low. And even if they weren't materialized by the time you're close enough for the trap to spring you'd be able to sense another Servant, even astralized." Argo gave a terse nod at the magus' assessment, finding it to be an accurate assessment of both her abilities and the situation. "That settles it. We go for Lancer. Try to sneak up if you can. Ending the battle quick would be best but watch out for any surprises."

A short "Un." was the only response Rin received before Archer disappeared into the Shadows. The magus sighed before focusing ahead setting a brisk pace as she headed towards the school. She need to observe the battle in case her Servant needed help.

Argo stared down her foe. After her opponent had leapt away from her first surprise attack, an uppercut using the short blades she held in between the fingers on her right hand, her claws, and the follow up vollies of throwing picks. However little she suited the archer class it did have it's benefits, namely that her knew found accuracy and speed with her picks allowed them to be used in tandem with her claws in even the most serious of fight. But it wasn't what had her focus. It was her opponent. Lancer, and the rapier they had drawn from within their brown cloak. Standing with their side facing towards her was a clearly feminine figure, one arm held out with the rapier in its grasp parallel to the clearly feminine figures side. The brown cloak cover most of their body only the positioning of their legs allowing The Rat to see the white metal shoes and white trimmed red combat skirt. Her foes was a defensive stance prepared to parry a coming attack, or, failing that, leap out of the way before dashing in with a counter thrust.

A fencer's way of fighting. Argo's stance more open claws ready to sweep in from the right and left hand already holding three more picks between her fingers prepared to throw them either as an opportune strike or to deter a charge. But their stance wasn't the issue. It was the weapon. A rapier, a sword in the hands of Lancer. And Argo was sure they were Lancer. As sure as she was Archer, from this close and her rank of Presence Detection, there was no mistaking it. Of course there were other factors to being a Lancer than having a shafted weapon. Speed and a low luck stat were well known common areas. And though she doubted Lancer would be willing to sit down for a game of dice so she test her luck. She was certain that her opponent's agility was somewhere around A rank at the speed she dodged, maybe higher. Argo doubted she could take victory here. That meant two goals. Gather as much info on her foe as she could, and give away as little on herself and her master as she could.

Damn, Archer knew that Lancer was fast but this was pushing it. She was barely able to deflect any truly damaging attacks with her claws while deterring the work of it with picks. A few picks had hit home over the conflict as her opponent dashed in she could throw three at a time. The trick was not putting them all in the same spot. Using one to get her to dodge and trying to hit where she dodged with the other two. Lancer had tried to jump over a volley once but gave up on the idea when gravity proved against her in limiting Lancer's speed so that Argo could get a scratch along her right shoulder. Argo meanwhile sported several light scratches along her limbs. A testament to all the thrusts she could not completely parry. Rin had arrived not long into the fight content to watch from the sides for the time. Probably looking for a way to either aid Argo or hinder Lancer. It was when they separated for a moment each side thinking new plans for engagement that a new comer attracted the attention of both Servants and the Master.

Shirou Emiya. Rin recognised, the Fake Janitor who ran around school doing whatever chores needed to be done simply for the sake of helping others. He was a tall man for japanese standards physically fit as well. Against any normal opponents in a fight. Any back alley thugs or school bullies. Well suffice to say Rin did not enjoy gambling but even she would put money on the red head. But Lancer was far stronger than any thugs school bullies. Which could end poorly seeing as how Lancer and her master had decided to remove any witnesses to the Grail War.

Story Stop

Archer: Argo The Rat

Strength D+

Mana: E-

Endurance: C

Luck: C+

Agility: B+

Skills:

Thrown Weapons: B+

Allows for most weapons of reasonable weight and size to become deadly projectiles in Argos hands. She originally wielded only picks as thrown weapons but her class as Archer has boosted it.

Independent Action: A

Argo was a solo player as much as one can be and still run the largest information network in Aincrad. She had her own plans agendas often ventured into the field on her own as well. The skill is further boosted as she is of the Archer class, one that naturally has Independent Action.

Presence Concealment: B+

Argo not only maxed her hiding skill within Aincrad but she was one of the first to do so. She used it constantly throughout the game whether to avoid large groups of enemies or to sneak up on Kirito.

Presence Detection: B-

Argo made great use of SAO's searching skill like many other solo players in Aincrad. It is a useful skill for one who seeks information. Allowing her to discover much about mob spawn points without fighting them as well as helping her hide from enemies since she knew they were coming.

Eye of The Mind(False): D+

Though not normally applied to battle Argo is skilled at manipulating people and information in order to obtain a desired effect. Her skill at such things is greatly decreased when applied to battle but it can still be used to aid her in obtaining victory.

Noble Phantasms will not be shown yet

AN: That's chapter 1. I thought it went well. I hope no one is too upset about the classes yet. I will say that is the worst of them and even those I have some justification for. Not just things like Lancer having high speed low luck and archer with independent action. Tell me what you thought. If it was shitty tell my why? What did you think of the fight? Its my first time writing one so I don't expect much. It was hard writing the fight scene from side as she isn't much of a fighter, more of a support character, goes out finds weaknesses and masters to exploit kinda deal. She fits Assassin class better but I have something planned for Assassin. So thanks for reading tell me what you thought hope to see you next chapter, when Shirou gets to summon.
