Jaune was surrounded, with no place to run or hide.

Yang was giving him the most full of innuendo stare she could muster, while Pyrrha face combined surprise, indignation and somehow anger. Ruby had the most excited of faces, while Saber looked lost in the middle of all his friends and class. Nora couldn't stop asking Ren all manner of questions, while the boy could only look at his team leader and his new friend. Weiss looked indignant over the boy that was just called 'master' by the new girl. And he was especially afraid of one person, Prof. Goodwitch that had a murderous look in her face.

"Mr. Arc, can you explain this interference in your fight?" She started, and Jaune gulped trying to find an excuse. He didn't count with Saber honesty and directness.

"I am Saber, I am a Servant." She stated, and Jaune got pale, while Prof. Goodwitch raised one of her eyebrows.

"A Servant, and Jauney boy here is your 'master'." Yang added full of second intents, amking Jaune cringe, while Saber ignored it.

"Jaune, care to explain why this girl calls you 'master'?" Pyrrha asked to him, her eyes those of a predator ready to attack her prey, and Jaune gagged.

"I am his Servant because I was summoned by my Master, and that is him." Saber said, her commanding voice causing everyone to admire her. Except Jaune, he wanted to die over the bluntness of her statement.

"Summoned?" Prof. Goodwitch asked, now properly curious over the two teenagers.

"Yes. Masters summon Servants by an ancient ritual that bound us together, so we can serve them." Jaune face palmed, that explanation giving Yang the biggest grin ever, while everyone started to give him some accusatory stares.

"She is my Semblance." He finally spoke, hoping that explanation could suffice.

"Wait, your semblance is a pretty girl?" Nora asked, jumping in excitement.

"Look, yesterday as I was walking around and found this old abandoned building behind Beacon, and somehow my Aura activated this magic circle, and summoned Saber. She is a Heroic Spirit, so she says." He explained, now receiving doubtful looks from everyone, but somehow the teacher didn't think he was making the story up.

"My Master speaks the truth." Saber added, and everyone whispered in doubt.

"It is bullshit!" Everyone turned to see Cardin entering the circle. "Look at her; she is probably one of his sisters!"

"Mr. Winchester, watch your language. And now, Mr. Arc, Miss Saber, do you have any proof of the veracity of your… tale?" The teacher questioned, finding everything indeed curious, as the girl showed conviction in her words.

"Very well, if proof is needed." Saber answered as her armor and weapon became dots of blue light and disappeared, now she standing there only in her blue and white dress. Prof. Goodwitch touched her arm; the heavy armor was not just invisible, but completely gone.

"Wow, how you did that!?" Ruby asked, poking Saber's arm only to feel her soft flesh.

"My physical body is a manifestation of my soul, and I am able to do so as my Master provide me mana, though you call it Aura." With that Prof. Goodwitch checked her own scroll and notice Jaune's Aura was depleting very slowly but steady.

"That seems impossible. Aura can't create physical matter." Weiss stated as a fact, but Blake disagreed to it.

"It can create my 'shadows', your glyphs and even Ruby's rose petals as she use her Semblance. While this… Saber is certainly nothing like those, if she is a Spirit, I can see the same logic being applied here." She said, and Ren chimed in.

"Her abilities certainly aren't common."

"I still call it bullshit." Cardin fumed, and Prof. Goodwitch looked at him making him shut up.

"Mr. Winchester, another outburst with foul language like that and you will clean all the bathrooms with a toothbrush." Her threat was not taken lightly by Cardin, which refrained of answering. "Well, it seems something is feeding of your Aura, Mr. Arc. And it seems that is indeed Miss Saber here. But you understand that we will have to run some testes to check your story. And be warned, if you are trying to fool me, your punishment will not be as light as bathroom cleaning."

"Aw come on? She is not a ghost! She is just using her Semblance to fool everyone! I will show you!" Cardin tried to grab Saber, but she just vanished in blue mist, he slipping right through it, and then she reappeared by his side, grabbing his arm and tossing him once again against a wall.

"Enough! Mr. Arc, Miss Saber, you are to accompany me as we will put your story to test." Pyrrha grabbed Jaune's arm and looked pleading at Prof. Goodwitch, and the teacher sighed. "Miss Nikos, as his partner I will allow you to accompany me. And as this seems to be a case for all of the staff will need to be consulted, so you are all dismissed of remaining classes."

"I still call it bullshit…" Cardin murmured just to feel one of Prof. Goodwitch's glyphs pushing him close to her.

"You will talk with the janitor and get a toothbrush with him, and he will inform me if you finished your assignment. Understood?" Cardin just nodded before being let go, and the teacher walked with Jaune, Pyrrha and Saber right behind her. Everyone else just gave curious looks at them.

The rest of team JNPR and team RWBY were at the mess hall, having lunch, though their main topic was Jaune's new friend. Yang was having a field day telling all types of dirty jokes about master and servant she could muster, to the utter embarrassment of Weiss and Ruby. Ren was trying her hardest to convince Nora that they couldn't just get a Servant, leaving Blake to her books. It didn't take long before Pyrrha, Jaune and Saber joined them back, the two girls talking together, Jaune looking tired.

"Jaune! What did they said?" Ruby was the first to ask as he sat down, while Pyrrha and Saber decided to get lunch for them.

"They believe me." He simple said, and every pair of eyes looked at him in disbelief.

"They do?" Ren said, barely showing any surprise.

"My Aura is being consumed by something, like a Semblance, and when they examined Saber, a lot of the tests returned inconclusive, outright off, or completely never seen before. So they concluded that Saber is indeed an Aura construct of a type never seen before." He answered as Pyrrha sat by his side and served him an unholy amount of food. Saber sat on the other side also with the same amount of food. "Since I can't just… stop giving Saber Aura, I just need to raise my caloric intake."

"Wait, are you seriously telling us this girl is your Semblance?" Weiss said in disbelief, analyzing Saber up and down. She looked like just a normal girl.

"It seems so. I was there and saw all of it. Basically, Jaune's semblance is having an impromptu… partner." There was a bit of sadness in Pyrrha's voice as she said that last word, but Jaune held her hand for a second, making her blush and look at his eyes.

"You are and always will be my partner, Pyr." He said with a smile, and Pyrrha felt a little better. He had that effect in calming her when she was distressed. "So, since she is technically my Semblance, I won't be punished for her interference in my fight with Cardin."

"So, this means she can fight with you in battles?" Ruby questioned, thinking that having a powerful warrior as a Semblance was the coolest thing ever.

"I will fight my Master's battles as long as they are noble, or if I am commanded to do so." Saber said, and they looked surprised to see she ate all the pile of food she brought with her and wondered where all that food has gone.

"Well, we don't know yet if she would be allowed in tournaments. But she will fight Grimm with us. Saber offered to train me, so with her and Pyr I hope I can not need to have my sorry butt saved every time." He said as he also finished his food, checking his scroll to see his Aura level was back to full. Apparently feeding Saber would really avoid him to lose too much Aura by maintaining her.

"So this mean Saber is a member of team JNPR?" Nora asked excited, and Jaune smiled at her.

"Sure thing. But first, there is a place I want to show you all."

All of them loved the place, despite it being dirt after such a long time abandoned. It was secluded enough that would allow them to be as loud as they wanted without disturbing anyone else. The place had enough space for practice, one of the reasons Jaune asked Ozpin if he could have the place, so he could be trained by Pyrrha and Saber without curious eyes looking at them. The stained glass called everyone's attention and was deemed beautiful. So with no more delays everyone started to help cleaning the place. They would fix the windows and the doors later, but taking care of all the dust and leaves inside was a priority.

"This place is awesome! It is like we have our own secret superhero base!" Nora exclaimed as she cleaned the stone walls with a wet mop.

"And we could have parties whenever we feel like it!" Yang added as she tossed rotten wood pieces outside. She was already planning the inauguration party in her head.

"I will see if I can get some furniture because we certainly aren't going to just sit in the floor." Weiss said as she helped Ruby cleaning the stained glass in the back.

"Ah, Mr. Arc, glad to see you are already at work. Hope this place can be put to a good use, and that none of you are planning to do anything immoral or illegal here." Prof. Ozpin said as he entered the spacious building, sipping on his mug, and Yang was sure he was looking at her while he said the last part.

"Oh, headmaster. So, any idea what this building was used before?" Jaune asked as he and Pyrrha stopped talking with Saber about the knight's training regimen.

"For now, we know only that this place was used for research in… arcane studies. Apparently this place was built at the same time Beacon was funded, but the first and only researcher was… eccentric to say the least, and after his death this place was abandoned." He explained, and Blake smiled a bit.

"Well, looks like the perfect place to summon spirits." She said, and Weiss and Yang shivered, what was the effect Blake wanted.

"Saber is not a ghost. Right?" Yang said, Weiss and she looked at Saber, and the knight girl scoffed at the thought.

"I am no mere ghost." She said, and Weiss and Yang left a satisfied sigh out.

"She didn't say she is no ghost." Blake added, receiving angry stares from the two girls.

"Anyway, this place is yours as long as you follow the rules. It is good to see students interested in keeping school property cared for. Also, your other requests have being granted, Mr. Arc. Your… friend is more than welcome to stay at Beacon. Just try to not get yourselves in trouble… Though considering your historic, I can't see you being able to do that." Ozpin added before leaving, the teenagers sharing some looks between themselves. It was clear that Ozpin always knew more than he let it show.

"Your headmaster is an interesting fellow." Saber said as she resumed talking with Pyrrha, and everyone nodded in agreement.

"What other requests?" Pyrrha asked Jaune, who smiled back at her.

"Well, some stuff to make Saber more comfortable. I know the staff is calling her an Aura construct, but I can't see her as that. To me she is our new teammate." Jaune explained, and Saber gave him a satisfied smile.

"So, Saber, are we sure you aren't related to vomit boy?" Yang asked as she looked at the knight girl, and she tilted her head.

"I would not know before examining his family tree." Saber added, before turning to a few new presences entering the building.

"Wow, you guys really struck gold here." Sun started as he examined the big space around and Neptune looked at Saber. "We can totally make huge parties here."

"Preach, brother!" Yang added and the two fist bumped and started planning the inaugural party together.

"I call dibs at the back room as a reading space." Blake already claimed the smaller room in the back, and planned to make it her personal library and a place she could read her Ninjas of Love books without fear of being found out.

"And we claim this space here…" Pyrrha marked a big square in the floor with her spear. "… As training grounds.

"Ren, Ren, can we have beanbags? And a mini fridge? And a soda machine? And a kitchen? Ooooh, a big TV screen big enough to be seem from the dorms?" Nora started saying super excited.

"Well, if we are claiming this place, we might as well add some amenities." Weiss said as she started taking notes, including many of the stuff Nora suggested, and Ruby also started giving her opinion.

"By the way, this is the Servant girl I was hearing about?" Neptune chimed in, and he started to examine Saber and gave her a shiny smile. Saber just stared coldly at him. "She is cute."

"My physical appearance has no importance." She said bluntly, and Neptune backed away for a second. "I am the sword that fights for my Master."

"Uh, she takes her job seriously." He said as he walked to join Sun and the 'club party' committee that now was formed by him, Yang, Ruby, Weiss and Sun.

"You need to light up a little, Saber. Besides you certainly are cute." Jaune added, and Saber blushed a little. Pyrrha noticed it, and felt a little insecure about her standing with Jaune now. After all, he had a Semblance that could easily defeat Cardin, despite Jaune's reassurance that he still wanted to be able to fight by his own, Pyrrha feared one day he would not need her anymore. "But then again, all girls here are cute. I am just happy Pyrrha and you are by my side."

The last comment made Pyrrha smile, even if it was not only towards her.

Soon Coco and Velvet appeared and joined them in discussing decorations, furniture and everything they need to make the place the club they wanted to make. After spending most of the day discussing the party and the amenities the place needed, they finally discovered one important thing. They hadn't named the clubhouse yet.

"So, we need to call this place something." Coco started, and they all gave suggestions, from dumb to inappropriate (Damn it, Yang!). But nothing seemed to fit the theme for a place to hang out with friends.

"Saber, do you have a suggestion?" Velvet asked the girl that was in silence for most of the time.

"A place where warriors meet to discuss important matter and socialize… We had a place like this at my time, we called it the Round Table, a place where everyone's voices could be heard and where positions of power didn't matter." She said as she looked like she was reminiscing something. Nobody at the moment though wanted to question her past 'life'.

"Oh, can we have a round table Ren?" Nora asked, and Ren smiled back at her, while Weiss added the item on the shop list.

"I think it sounds grand. A place where we can all freely state our thoughts." Pyrrha added, and everyone agreed the idea was good.

"So it is decided. This place will be our Round Table." Jaune declared as everyone approved and they called it a day, returning to the dorms.

Nora opened the door to JNPR's room to find that one of the beds was changed for a bunker bed (a proper one, not the improvised deathtraps team RWBY made) and looked at it, the bunker was in place of the one Jaune usually used. On the top of it, several sets of the female uniform.

"I asked for Ozpin for some uniforms and the bunker bed so Saber could sleep with us, and she will be allowed to study with us. I think it would be nicer than just let her disappear and appear over convenience." He explained, and everyone of the team agreed it was just fair, with Nora hugging Saber tight, making the knight girl blush, yet she felt a bit of happiness over the gesture.

"Now we are team JNPRS!" She celebrated. Weiss on the other hand was glaring daggers at her own team.

"So, we could just have requested bunker beds." She coldly growled, as her team rushed inside their room and closed the door. "You can't hide from me forever!"

"Does this change our plans?" Mercury asked to Cinder, as they reviewed footage of Saber sudden appearance in the combat class.

"Any new element need to be analyzed carefully. We don't want this… girl to be an unknown variable in our plans. So, for now, we keep an eye on her." Cinder answered closing her scroll.

Somewhere in Vale, in a dark abandoned building, a man stood surrounded by old books of an age past and forgotten. He also was watching the video posted in the net with a great deal of curiosity, a creep smile in his face.

"Ah, a Servant was summoned… So I am correct…"

A.N.: So, decided to post the two first chapters of this crossover for your appreciation. I will resume this story as soon as I am back from my trip, by the end of the month. It is easier to write a story when you don't have to care about canon and what should you deviate from and what not. At first I was going to give everyone in RWBY and JNPR a servant, but decided against it as juggling too many characters would kill me.

So, Saber was not going to be the only Servant though, I intend to add two more on the mix later on. I also don't plan to follow the darker tones from FATE, but the lighter ones from RWBY. Hope I can do good o both shows. ^^
