Hermione Granger prided herself on being well read, and as such was easily able to recognize various things in the magical world she now found herself a part of the instant she saw them, regardless of how obscure they might be in the Muggle World. That was why she had fainted when Harry had introduced Medea, Stheno, and Euryale to her, she knew exactly who those three names belonged to and what they were famous for.
Yet for all her diverse knowledge, nothing could prepare her for what was playing out in front of her very eyes. There in front of her, her best friend, Illyasviel von Einzbern was cuddling up and cooing over one of the most feared Magical Creatures in existence, and the creature seemed to be soaking up her affection like a newborn puppy of all things!
"Illya… can you explain why we aren't dead?" Hermione asked in disbelief.
"Oh, probably has something to do with the fact that I have Primate Murder's scent on me due to longstanding association with the Wolf." Illya stated.
"I am afraid to ask… but what did this particular wolf do to earn the title of 'Primate Murder?'" Hermione asked, having never heard of such a wolf.
"Simply existing isn't enough?" Illya asked in confusion, before glancing at the girl and seeing the confused look on her face. "Oh… right, first-gen… um… Primate Murder is the given name of the Beast of Gaia, the Slayer of Mankind."
"Oookay then… how exactly is it you aren't dead?" Hermione asked.
Illya smirked and said "I am not exactly human… well actually it's more like I am only half-human."
Hermione frowned, "So you're what, Half-Veela or something? That would probably explain the hair…"
"No… not Veela. By the Root, we have enough supernatural pheromones in the air with just Stheno and Euryale being in the school, last thing we need is one of that species to be present as well… No, I am half-Homunculus." Illya said.
"I thought the magic used to create Homunculi was banned by International Decree…" Hermione said in confusion.
Illya snorted in amusement, "I would have liked to have seen the face of whoever had been sent by the International Confederation of Wizards to inform my family of that fact when or personal guards got through with them. Hermione, my family has been in the business of creating and utilizing Homunculi since at least the late 1700's. And if Artoria is to be believed, Mordred was a Homunculi as well."
Hermione nodded in understanding before saying "With how much crap I get from the Slytherin's… well other than Stheno, Euryale, Daphne, and Tracey… I can't help but think it is a good thing that you weren't sorted into Slytherin…"
Illya snorted again "Please. Had I been sorted into the Snake Den I would have been declared the Queen of the House before the first night was over."
"How do you figure that?" Hermione asked.
"Well… first off I am good friends with the Goddesses of Snakes, who are only really members of that house because it amuses them, and irritates Draco-teme. Second… my glare is rather hard to ignore."
"Huh? I am sorry, I don't understand…" Hermione said in confusion.
"How familiar are you with the myth surrounding Stheno and Euryale's sister?" Illya asked.
"You can turn people to stone?" Hermione asked with a trembling voice.
"Hardly… I have what are called the Mystic Eyes of Binding. Basically my eyes act as a really powerful version of the Petrificus Totalus jinx when I channel prana into them… and it would take a Magi to counter the effect as it requires the ability to disrupt the prana within a person's body, something Wizards have no idea how to do. Point is, if the Pureblood Bigots annoy me too much, I would just hit them with that and leave them alone for a few hours."
"So why didn't you just use that on Malfoy on the first day instead of punching him?" Hermione asked.
"Because Malfoy had the balls to try to dictate who Stheno and Euryale could associate with. As such I felt he needed to be made an example of. The transformation was mostly for dramatics though. I could have delivered just as powerful a punch without doing that. Only people in this school who would be able to take my punches are Stheno, Euryale, Medea, and Harry. Harry is only able to pull it off by reinforcing his body a fraction of a second before the blow lands. On other hand, I would probably have needed to pull out one of my Noble Phantasms to be capable of injuring Stheno, Euryale and Medea."
"Huh?" Hermione asked.
"Servants are generally immune to all forms of attack that do not involve some form of Mystic Code. Wands and Reinforced Limbs do not count as Mystic Codes. No… for that you need truly ridiculous things. While I do qualify as a Mystic Code on a fundamental level, for the most part that fact is largely useless in combat situations. Or at least it was until Zelretch-baka gave me Ruby and the Archer Card."
Suddenly the door to the room opened, Hermione blinked as a purple blur rushed past her and glomped the Cerberus as a girlish shriek of delight was heard uttering the word "KAWAII!"
"What the?" Hermione asked as she realized one of the twins had just found them.
"Greek Myth, Hermione, of course she would be familiar with the Cerberus."
Hermione looked at the Twin in question and realized that this was Stheno, or at least she thought it was Stheno. She could never really be sure with these two.
"Hades-sama was one of the few Gods who we actually got along with. Mainly because he wasn't constantly trying to seduce us the way half the other Gods were trying to do. Say what you want about the God of the Underworld, but he is a devoted husband." Stheno said. "He usually allowed us to play with the puppies."
Just then Medea stuck her head into the room and groaned "Oh, well now that just figures. I think I am going to go locate Ruby and pester her to summon Zelretch."
Illya smirked, reached into her school bag and pulled out a hogtied Kaleidostick.
"Oh dear, what did she do to deserve your ire this time?" Medea asked.
"I might have caught her trying to sneak into the Prefects Pool…" Illya stated.
"Pool?" Hermione asked.
"Well… they call it a bath, and it was clearly the intent to duplicate a traditional Japanese Hot Spring, or Ancient Roman Bathing Facility… but what they ended up with was an overly fancy clothing optional swimming pool." Illya explained. "And to make everything worse the whole thing is completely co-ed."
Hermione's face lit up in a brilliant blush as she comprehended what Illya had just implied.
"How'd you manage to stop her from complaining?" Medea asked.
"Fred and George were kind enough to teach me the Silencing Charm, all that had been left was tying her up with Prana suppressing rope." Illya said with a smirk.
"Oh that is rich." Medea said with a laugh.
Elsewhere in the world, a raven haired girl was cursing the fact that she couldn't silence her own wand or stop it's perverted antics.
Illya untied the rope and canceled the Silencing charm, glaring at the Kaleidostick, "Summon Zelretch, NOW!"
"Why I never…" the Kaleidostick muttered before glowing momentarily and then flitting off before Illya could rebind her.
Suddenly a voice spoke out from behind Hermione "You rang?"
This had the predictable effect of causing Hermione to jump into the air and spin around with her wand pointed at the man. "The hell?"
"Hermione Granger, allow me to introduce the Wizard Marshal of the Clock Tower, Kischur Zelretch Schweinorg, the Troll of the Multiverse." Illya said haughtily.
Zelretch pouted at that, "Oi, I will have you know… wait… no actually you are entirely correct."
Zelretch then took in just what was in the room. "Oh… huh… would you look at that, a breeding male."
Illya scrunched up her face and palmed it before saying "Oh no... Auntie is going to kill me…"
Medea took a few moments to digest that before breaking down laughing, "Doubt it. Though Gaia is probably going to be annoyed."
Zelretch smirked, snapped his fingers and the big dog vanished from the room. Zelretch took in what had been underneath the dog, and then grinned, "Huh… now if I remember correctly from what Black Wing has told me… there should be a rather pitiful obstacle course below that trapdoor that any Servant worth their salt could demolish in under five minutes… and at the end of that obstacle course is the ultimate Dark Wizard bait."
Illya silently mouthed out the last four words that Zelretch had just said, before she pulled out the Archer Card and declared "Install."
In a flash of light she had become Archer yet again. Only this time, she wasn't holding back. "Trace, On! Caladbolg!"
Zelretch whistled before saying "Have fun with that. I think I am going to head on over to another universe for a little while." and vanished.
Illya opened the trapdoor and dropped down the hole. Only a few seconds after she had done this there was a massive shockwave emanating from the hole. Medea couldn't help chuckling out, "Caladbolg one, whatever was at the bottom of that hole, zero."
"What on earth was that?" Hermione asked in a panic.
"That Mione-nee-san was the shockwave unleashed by a Noble Phantasm being used on its lowest setting." Stheno stated happily.
"That particular Noble Phantasm, when operating at full power, is capable of blasting the tops off of mountains." Medea stated with a smirk.
"Bloody hell…" Hermione swore, something she almost never did.
xXx With Archer Illya xXx
Almost as soon as she had landed on the ground Illya had been forced to unleash the power of Caladbolg in a downward slash. "The bloody hell? Devil's Snare? Really?"
Once that threat had been dealt with the girl quickly made her way down the corridor and to her frustration found herself in a room with a bunch of flying keys, a rather rickety looking old broom that had clearly seen better days, and what was obviously a locked door sealed against magical methods of opening it.
Illya sighed, "It's like the old coot has never met a Magi before. This would be child's play to any Magi who bothered to come here. just looking at the lock would allow them to utilize Graduation of Air. And this is of course ignoring… Trace On!"
Just like that a perfect replica of the key to the lock appeared in her hand. "All I had to do was glance at those keys. Pitiful." With that she walked to the door and unlocked it.
Illya took one look at the next room and swung Caladbolg at its contents, annihilating the entire chess set in one stroke. She then proceeded to the next room.
This room however caused the girl to hesitate momentarily. "The fucking hell… a troll? Trace On! Enkidu. Bind!"
As soon as she said it golden chains sprung out of thin air and wrapped themselves around the troll tightly, completely restraining the behemoth. Once the beast was restrained Illya casually walked up to the beast and stabbed the tip of Caladbolg straight into the beast's left eye. As soon as it made contact the blade of Caladbolg spun like a rotor and scrambled the Troll's brains like so many eggs.
"Enkidu, Trace Off," Illya said, dismissing the golden chains. She then proceeded to the next room.
As soon as she had crossed the threshold she spun around in shock as purple fire appeared in the doorway she had just entered from. Frowning she turned back to the room only for her frown to increase in magnitude at the sight of black flames blocking the doorway to the next chamber.
"Caladbolg, Trace Off… Trace On, God Force!" Illya intoned. The spiraling sword that she had been carrying since coming down here disappeared into a multifaceted light, only to be replaced by a truly massive spear.
"Juu" Illya stated, causing the spear to reform itself into the shape of a golden longbow. Illya took aim at the wall to the side of the black flames and exclaimed "SHAGEKI!"
The arrow portion of the Noble Phantasm transformed into a beam of pure energy as it launched itself at the wall, and proceeded to atomize the entire section of wall. Illya whistled and said "And that was at it's lowest setting. Anti-Fortress Noble Phantasm indeed."
Illya idly took note of the table full of potions and read the paper on it, snorting she pocketed the potion that would see her safely through the purple flames before entering the next chamber.
Upon entering the room, Illya came face to face with a twelve foot tall golden, and yes, it was real gold, she could tell just by looking at it, mirror. What was peculiar about this mirror was that it had the word "Erised" engraved at the top of it.
Illya walked up to the mirror and said "Trace - Analyze."
In this way she was able to judge the concept of the mirror's creation. From there she could hypothesize the mirror's basic structure. This in turn would allow her to duplicate the mirror's composition materials. After that it was simply a matter of allowing her magic to mimic the skill of its making as well as sympathizing with the experience of its growth. All she had to do after that, assuming she wanted to duplicate the mirror was to reproduce the accumulated years the item had existed and then she simply needed to excel in every manufacturing process.
These were the steps involved in Gradation Air's Projection (Trace version) technique perfected by the Counter Guardian EMIYA and duplicated by Zelretch to be housed in the Archer Class Card. Through the use of this technique the manifestation of the Reality Marble "Unlimited Blade Works" was entirely possible.
However what this technique also allowed Illya to do, "Why that old Goat… Zelretch was right when he said the ultimate Dark Wizard bait was down here. I wonder how highly Nikolas Flamel would repay me for retrieving this for him?"
Illya stood in front of the mirror with the clear intention to find but not use the object housed inside of the mirror. Her reflection winked at her and dropped a red rock into her pocket. As soon as it entered the reflections pocket, Illya herself felt a weight appear in her own pocket, smirked and turned to leave, only to come face to face with a scowling Headmaster Dumbledore.
"Um… hi?" Illya said, "How'd you get past Stheno and Medea?"
Dumbledore raised a single eyebrow and said the word "Magic."
"Right, Headmaster, forgot, that means you can apparate inside the school," Illya stated blandly.
"I must ask you to return the stone to the mirror dear girl." Dumbledore stated in his most grandfatherly tone of voice.
"Not happening," Illya said as she began walking towards the hole in the wall.
Dumbledore's wand was out in a flash and aimed at her as he silently cast a spell at her. Much to his shock and surprise the spell impacted against a large pink flower-like barrier that materialized out of thin air between him and the girl.
Frowning, he cast another spell, this one vastly more powerful, in the hopes of shattering whatever barrier spell the girl was using. Much to his frustration this too had no effect.
"I hate to inform you of this Headmaster, but no Wizarding Spell in existence will ever be capable of breaching that shield." Illya stated.
Dumbledore frowned, "I find that hard to believe, no shield spell can block the Unforgivables…"
Illya smirked and said "By all means, test that theory."
Dumbledore scowled at the girl, "Are you truly so confident in your shield spell that you would willingly allow someone to cast one of the Unforgivables at it, and thus at you?"
Illya smirked and said "What you have failed to comprehend is that what is protecting me from your spells is nothing so simple as a spell. What you see before you is the projected form of Rho Aias, the Seven Rings that Cover the Fiery Heavens. It is an A++ Rank Barrier-type Noble Phantasm, not a spell." Illya stated.
Dumbledore looked shocked at this statement, but Illya wasn't finished, "The only things in existence which hold superior defensive capabilities are God Hand, the Twelve Labors; Lord Camelot, Fortress of the Distant Utopia, and Avalon, the Everdistant Utopia itself. And while the Elder Wand that you are holding is indeed an impressive offensive Noble Phantasm, it won't help you in defeating this shield as you are not properly attuned to the Elder Wand and are as such incapable of bringing forth its full potential."
With that all said, Illya disappeared through the hole leaving behind a thoroughly shell shocked Headmaster.
xXx Several Days Later xXx
xXx Dinner Time xXx
The Students of Hogwarts were eating their supper peacefully when suddenly the doors of the Great Hall banged open to reveal a tall man with long black hair. At his side was a young woman who looked to be maybe fourteen with long raven colored hair and blood red eyes.
Harry and Illya looked up from where they were sitting and twin cries of "Mum!" and "Auntie!" ripped through the hall.
Draco looked over at the woman that the two had addressed and scoffed, "Don't make me laugh, that can't be your mother, Potter, she's barely older than I am."
Stheno, Euryale and Medea winced and cupped their hands before saying "Lord Zeus, have mercy on his soul, he knows not what he is saying."
Normally the three of them wouldn't even bother praying to Zeus or really any of the Olympian Gods, but they had collectively figured that Zeus was probably the only God in existence who would bother protecting the pompous blonde. What the didn't expect was the ringing sensation in their heads that sounded like a man cracking his gut laughing at them. So they didn't hold out any hope that the blonde was going to survive this encounter.
Faster than Draco could blink, the raven haired beauty had appeared in behind where he was seated and gripped his chin forcing him to look back at her, when he did so, she grinned a smile that allowed him to see very clearly the inhumanely large canine fangs she had allowed to become visible for his benefit.
"I assure young man, I am more than old enough to be Harry's mother. Now why don't you be a good little boy and mind your own business lest I placate my thirst." Altrouge said rather viciously.
Dumbledore stood from where he was seated at the Head Table and asked in a loud voice "How did you get past the Dark Creature wards, Lady Altrouge?"
Altrouge diverted her attention from Draco and looked up at the old man and grinned saying "I got past them by virtue of the fact that Camelot recognizes me as the Guardian of its new Lord, and decided it would be futile to try to bar me entry."
"What do you mean by 'Camelot'?" Dumbledore asked.
Altrouge laughed, "Oh you poor Wizards, you forgot your history. Hogwarts as you call it, was the Court of Artoria Pendragon, otherwise known as Camelot. It was ever the surprise to her when we pointed out where Hogwarts was on a map of Britain."
Suddenly a voice spoke up from the Gryffindor table, "Don't be stupid, King Arthur has been dead for centuries."
Medea decided to stand up and said "Um… yes… hello remember me? Princess Medea of Colchis was how I was introduced during the Sorting Feast if I remember correctly, was it not? Can anyone here tell me when I was supposed to have lived and died?"
Daphne smirked and replied "Something like 2,500 years ago if memory serves me correctly."
"Indeed, now would anyone here like to explain to me why I can be alive in the current era, but for some reason King Arthur can't?" Medea asked.
The same annoying voice from the Gryffindor Table spoke up again and said "Obviously you're just pretending to be the historical Medea."
Suddenly Stheno, Euryale, Illya, Harry, Hermione, Daphne, Tracey, Altrouge, AND the mysterious black haired gentleman broke down laughing.
"Pretending is it? I wonder…" suddenly there was a squawk of indignation and fear as the red-headed git from that first Potions class was lifted into the air with no obvious method of support nor any obvious signs of spellcraft being used. Just as suddenly the night sky depicted on the roof of the Great Hall was replaced by the appearance of sunlight overhead.
"This is just a taste of the abilities of one of the most powerful spellcasters to have ever lived. The things I can do if I truly put my mind to it would make even Merlin's skills look like parlor tricks by comparison." Medea stated calmly.
"Why exactly are you a student in Hogwarts since you clearly don't need the magical education?" Septima Vector asked.
The black haired man frowned and said "I see. So that means that aside from spoiling the secrets of their identities, Dumbledore failed to enlighten his teaching staff about the true nature of these girls, and if I were to judge by the way that several of the males in the room were looking at the twins, he also failed to inform the student body that Stheno, Euryale and Medea aren't 'on the market' as people say these days."
McGonagall sniffed and said "No he did not, but I quickly figured out what was happening when I read their names on the student roster. I must ask how Harry is able to maintain three of them, when as I understand it the Grail War isn't for another ten years or something like that?"
"That is need to know information, and I am sorry but this school's faculty simply doesn't need to know." Altrouge stated. She then turned to address the students at large, "I am here to formally announce the betrothal between Harry James Potter, Daphne Anne Greengrass, and Illyasviel von Einzbern, as well as to put it on record that Stheno, Euryale, and Medea are considered by magic to be the familiars of Harry, as such any and all attempts to force them into unwanted marriages will automatically fail the moment such an attempt is made, so don't even try."
"On that note, Illyasviel, do you have the object you mentioned." The old man inquired.
"Yes sir." Illya said, getting up and walking over to the man, pulling a brilliant red gem out of her pocket and handing it to him.
"THE STONE!" a voice hissed as Professor Quirrell stood up brandishing his wand and screeching out "Avada Kedavra!" The blinding emerald jet of light rushed towards Illya and would have killed her if not for there suddenly being a body between her and the light.
Illya looked up to see Altrouge standing as a shield in front of her, "AUNTIE!"
Altrouge turned to smile at the girl before glaring at the man who had just fired an unforgivable at her niece, "Forgive me the nightmares I am about to give you children, but this will be far from pretty!"
With that Altrouge vanished from where she was standing in front of Illya only to reappear in front of Quirrell with her arm outstretched. What had just happened was not at first apparent, but it took Quirrell all of to seconds to crumple to the floor as her arm was forcibly removed from his stomach leaving behind a gruesome hole that splattered blood virtually everywhere. She then reached down and grabbed the man's neck, biting into it with her ginormous canines and bit down, draining the blood that wasn't spilling everywhere. She however was forced to spit it out as it was tainted by foul magic. "Gah. A horcrux parasite. Well no matter this fool is as good as dead, the parasite can be dealt with later."
She then tossed the corpse to the ground and returned to Illya and pulled the girl into a hug, despite the overwhelming amount of blood covering her dress. She did this largely because Illya had panicked at the sound of the spell and the fact she had no actual defenses in this form. "Shh Illya-chan, it will be alright, the threat has passed, you are safe now."
Many of the other students were positively horrified by what they saw. Harry and his group rushed forward to comfort Illya.
