Note: Apperently - judging by the lack of angry replies - so far so good! Let's hope it lasts...

Note: Just an FYI - this is first person. This means that whatever the main char says (and any other for that matter) doesnt have to be truth. It could be a lie/misdirection/lack of knowledge/half-truth/etc.

Note: Also, this is Fate/Stay:Night and Sekirei crossover. Not Fate/Zero or any others...I have difficult enough time following the triple mess that is Fate/Stay lol...

"You know," I casually stretched, watching Brunestud meditate. "You still haven't explained to me just what the hell Gaia, Akasha, Aristoteles and other crap really are."

"Is now really the time, Rei?" His crimson eyes opened and he focused his gaze on me, disgruntled. "I am finishing up the preparation for the ritual; my connection to this failure of a descendant of mine is practically non-existent at all. Any distraction could result in him getting the wrong message or worse!"

"Aren't you concerned that sending me unprepared will compromise this chance of yours?" I asked my lack of preparation definitely a concern for me. I have this one chance to return and the fact that I may lose it due to Brunestud rushing things is quite aggravating. I've waited for this chance for far too long, I could wait a little bit more now rather than lose it entirely. Going into this new world completely unprepared and knowing nothing about it whatsoever was something I was definitely not eager to do. If they can summon Legendary Spirits and have people who can take on Brunestud…

Speaking of which, just who the hell is he? From the tiny scraps he told me, this 'Traveler' is an Aristotele – whatever the fuck that is – and he was sent in by Gaia – ah yes, the so called 'Spirit of the World' – to destroy Humankind. With him came another Aristotele – Type Mercury, what kind of a name is that? – but they decided to sleep instead. Brunestud, on the other hand, went around the world, met new people and – quite likely – killed them too. And then someone killed him. Ha, I smirked, that must've been a fight to see. I couldn't imagine him simply falling over and dying after all.

"Look," I turned to him, eyebrows raised as he spoke out. "I'll stay here, in your Reality Marble or as you call it, Inner World. This means, that whenever you go to sleep we'll be able to meet and communicate. I'll tell you whatever you want to know."

"However," He continued right away. "You must understand. Time is a flexible thing here so I need to get this done as soon as possible. I'd rather have you arrive early then late, these 'Grail Wars' last only a couple weeks at most once everyone is summoned after all."

After seeing my nod he smiled in return.

"Don't worry," He closed his eyes once more. "I will do everything I can to ensure your success… even give that failure of a descendant my blessing once he becomes your Master."

"My…what?" Brunestud opened his eyes again and looked at me warily, my ice cold tone clearly setting him on the edge.

"Masters are the ones who summon and anchor the Servants – the Legendary Spirits." He explained carefully. "Normally, Servants can't exist without their Masters who feed them prana and provide the anchor to the world. Without a Master, Gaia would reject the Spirit from existence as they are unnatural to it. A failsafe of sorts, making sure that no Spirit decides to roam the world for ever after killing their Master."

"…Is that all?" I pressed on, tired of the 'Traveler' evading the heart of the matter. "These Masters wouldn't just happen to have something that allows them to enslave their Servants…right?'

"All Masters receive 3 Command Seals – 3 absolute commands the Servants Must obey." Brunestud replied evenly, his eyes on me. "Supposedly, a single Command Seal can be overpowered with sufficient will but 2 or more are impossible to resist. However, these Command Seals are a finite resource and getting more is impossible."

Silence settled over the roof top as we watched each other. Brunestud waited for my reaction while I tried to reason with myself – a feat that was proving to be surprisingly difficult. The very notion that someone other than Chiho could be a Master for me was Alien. A simple impossibility. My brain could reason all it wanted but my Tama would accept no one but Chiho. It was simple, really. Anyone who tried to subjugate me and wasn't Chiho would die. Period.

"I'll give this 'failure' of yours 1 chance." I finally forced myself to say, practically fighting myself the whole way. "But the moment they try to order me, I'll murder them."

"I see." The man replied simply. "I passed it along."

"Speaking of passing along," He got up in a single fluid motion. "You should get ready; the ritual could begin any moment now."

"That's…fast." I remarked, watching him. "Weren't you just talking to him?"

"Time flows strangely here." Brunestud shrugged. "We are far enough from the planet that it's time constant isn't quite so constant anymore at all."

"Besides," He grimaced. "From the little I got from that fanatic, he'll get started immediately, cover and preparation be damned."

"You should be ready to fight the moment you arrive actually." He added as an afterthought after a second. "Humans do not get along with my descendants at all and this ritual is bound to attract quite a bit of attention if all goes according to plan."

I merely nodded as I turned back to watching my world. Seeing as Brunestud wasn't going to be answering my questions, there was little else to do here anyway. Besides, human presence was really irrelevant. All I'd have to do was swap up into the Spirit Realm and that'll be the end of that. Nothing from the Living Realm can affect the Spirit Realm after all and vice versa.

Honestly, my plan so far was simple. Get summoned, gather information, kill the opposition – going after the Masters sounds like the best idea. Really, just the whole 3 Ultimate Commands were enough of an excuse for me to go specifically after the Masters. Speaking of which, I sincerely hope that this descendant of Brunestud is an agreeable person. I'll need them, at least at the start, to get myself some armour and weapons. I may be sitting here in my red and gold armour along with my swords in my sheaths but my real armour and blades were back on Heaven's Feel, on my cold corpse.

Afterwards… well, if they prove to be a decent being maybe we'll stick together. Otherwise, I'll just force this Gaia to accept my presence. Whatever this being is, if they called upon the likes of Brunestud for help then they can't be all that powerful. I should be able to overpower them…I think. I mean, I really haven't used my accumulated might for anything. Crushed and annihilated a couple souls to test it but that was just brute force. Tried to use it to move myself but no matter what I did it ended in a failure.

Okay, so I won't force the issue. I'll legitimately try my best not to kill this 'Master' when they slight me. I'd really rather not try to take on this so called 'Spirit of the World' really – not without more information. Who knows, maybe it's an Elder God from Lovecraft or something. I shuddered, mentally making a note to smack Haihane for getting me to read the Necronomicon. As if I didn't face enough real horrors…

"How do I know who your descendant is?" I asked, still watching the horizon, eager to get Lovecraft off of my mind. "Do they have a name, similar looks or something I can use?"

"They should have red eyes…" Brunestud took a seat nearby. "Actually, I have no idea how they look like. Just ask if they are a Dead Apostle or, as humans occasionally call us, a Vampire."

"A Vampire." I asked incredulously.

"I am not particularly keen on that name myself." The man shrugged, misinterpreting my surprise. "But it should be enough to recognise them."

"Oh, almost forgot." He snapped his fingers. "Dead Apostles can't be the Summoning Masters, yet another failsafe. But they can be Masters of a Rogue Servant."

"So someone else summons me and then your…Vampire, kills them to steal the link?" I clarified abscentmindedly, still coming to terms that Brunestud was apparently some Vampire Ancestor. Huh, considering he came from outside, does that mean that the vampires of this reality are Aliens? No, seriously. Alien Vampires. Probably Magical Alien Vampires too if my luck holds.

"Just a forewarning." I stared at Brunestud with steel. "If your descendants are some sort of bullshit Magical Alien Vampires who sparkle under sunlight I'll annihilate them all."

"…Most of my failures of descendants fall apart under sunlight." Brunestud spoke slowly, clearly wondering if I had perhaps had a bit too much alone time here in the void. "They most certainly do not…sparkle."

"Oh good." And with that a silence settled back in. Brunestud was clearly confused about the whole thing and I simply watched the horizon, waiting for the-

"Huh." I frowned as I felt…something. It was as if a link was established to me directly and I felt souls begin to travel down it to me, instantly transferred through my Gate. I also felt a slight pull down this channel as if all those souls were a…swap? Just what the hell is this ritual?

"I'll wait for you here," Brunestud distracted me as he put his hand on my shoulder and squeezed a bit. "Good luck."

I barely had the chance to glance at him and nod when I felt 5 more strands connect and begin pulling me. It was…weak. It felt as if had I so much as twitched the wrong way, all of those ephemeral connections would've shattered instantly. So I carefully willed myself to move with the strands…to the usual effect. As in, nothing happened. The strands pulled my consciousness away from my body…soul…uh, something? Anyway, only a relatively tiny part of me was pulled away, the rest remained in the same place. I still felt the rest of myself easily and the connection was crystal solid so I merely remained still, letting myself be carried.

I tilted my head, curiosity rising, as I began to hear things. A voice was chanting…something. I couldn't tell what it was but the voice was…female? It was also familiar to me somehow and full of resigned fear. It grew – from a barely audible whisper to an easily audible voice as if the person stood right behind me. But I still couldn't understand what she said, it was as if the meaning escaped me…or something blocked it. On closer look, I could see not 6 but 7 strands pull me, except that the 7th seemed almost non-existent and focused more on the rest of the strands rather than me. I bet I could get rid of it but right now I was too cautious to so much as twitch – so fragile were the strings that pulled me. So I let it be, just watching.

Suddenly, I was assailed by a conglomerate of most random images and scenes imaginable. Some – like the location of Fuyuki, the city where the Grail is located, the knowledge came – was useful. Others – like schematics and gear shift of a manual car – were…odd. I mean, I guess learning to drive a manual – a concept obsolete and practically useless in my time – might come in handy but why the hell would I need something like a mechanical pocket watch? I mean, I guess it's interesting to know just what was inside Kara's pocket watch that she inherited from Dietrich but…

Suddenly, the pull abated quite a bit, even as I could tell that I was almost there. The voice, it's incantation illegible but an instant ago, suddenly was clear.

"If you answer the call of the Holy Grail and if you submit to my will and reason – respond!"

And once more the female voice descended into gibberish, something preventing me from understanding. The same 'something' which just happened to be the 7th string – suddenly hell of a lot more powerful and solid. Nothing I couldn't break but it was far too entwined with the other strands for me to break safely. Hmm, I guess that that is the Grail itself huh? It won't let the summoning complete until I agree to these 'Terms of Service' so to speak. Well, nothing to it, I mean – I already agreed to this when Brunestud explained it.

The moment I thought that, the pull suddenly accelerated and 7 sigils lit up before me – transferred from the Grail connection. One of them was grayed out, clearly unavailable or something. I barely had the chance to acknowledge them when they all – save for the grayed out one – flared into life and I could feel each one reach out and try to interact with me somehow. I didn't know what they did but slowly, 1 by 1, they dimmed until only 1 remained. For a second it glowed softly until it flared and…locked? I couldn't explain how I knew, but I now knew that that sigil is my…class? The hell is that?

The Grail answered me the moment the question formed in my head. Each Spirit is assigned an archetype – a class – that fits what their Master want and fits their skillset the most.

I was distracted from the sigil as suddenly I felt...arrival. My eyes widened as I felt that I'll arrive in but a moment to where ever I was being summoned. I made to ready myself – my hands gripping the hilts of my blades – when the Grail suddenly sent a powerful pulse. It took the advantage of this moment of surprise and helplessness and I felt a trio of chains wrap around me. The Command Seals, the realization came to me. They disappeared almost as instant as they formed, but I could feel them, their existence so very real if intangible. The Grail used it's connection to me to install them and at the same time explain to me that their existence chained me to reality – to this…Earth. And finally, in the last moment, it told me what my sigil meant – what class I was.

Assassin.

My Arrival wasn't very…stable. I felt myself slam onto the ground, the shock of the rapid transition unbalancing me. All around, quickly dissipating smoke obscured my surroundings. Not that I paid them any attention. I was far too busy staring at my hand that I lifted before my face, examining it and – more importantly – the world's effect on it. In my Inner World I controlled Everything. Even subconsciously. Now…now I relished the simple feeling of air and the pressure, the smoke itself. Relished, knowing that it wasn't me who ordered it to exist.

I…I was alive once more…

A whoop of joy distracted me and I finally took a look at my surroundings. Surroundings that made me blink and look again. I stook in a complex looking circle on the roof of some building in what looked like the center of a small town. All around me was blood and corpses. Dozens, no, hundreds of corpses in various stages of dismemberment. And right before me were 2 people – the only ones alive here. A blond man with red eyes and an unhinged grin who did what looked like an extremely weird victory dance with his bloody ritual dagger on the spot. And-

"Ch-Chiho?" I whispered, unable to comprehend what I was seeing. Before me, in a hospital gown, her light brown hair almost silver under the bright full moon, stood my Ashikabi. She looked a bit different – extremely tired, wary and with deadened eyes – but it was her! She even startled a bit when she heard me and our eyes met for a moment.

"Ah yes, I almost forgot." The man suddenly stopped as he saw us look at each other. "Thank you for your help Miss Hidaka and goodbye!"

And with that the vampire drove the dagger in his hand into Chiho's throat.

Reply: I did consider Rei as Saber. But she really doesn't fit the class. I mean, she'd be the most underpowered Saber of all time. If anything, Kara should be Saber. Ah yes...the picture of her blasting her Norito at Gilgamesh...

At least Kara's Norito can rival quite a few Noble Phantasms. Rei on the other hand...

Question: I am wondering about adding an Appendix of sorts that explains the world/abilities/etc as they appear. It'll be put into the end of the original story but I wonder if it's even warranted...
