People keep saying that, but actually the whole Nasuverse hangs together really well and we get references to new mechanics and events ten years and several works in advance. Try playing Melty Blood after the first arc of Grand Order, for example....
At this point I'm attached to using "Bounded Field" = "relative to The World" because that mostly matches how it's used everywhere else in the setting, both in detail and especially in theme.

Well, it is in fact canon, but there's an explanation consistent with the rule you've already given --

Fate/Zero Book 2 said:
The ability to separate the passage of time inside a designated space from the flow of time in the outside world—in some ways,
Time Manipulation could be regarded as a type of Reality Marble. Although classified as greater magecraft, it was definitely not unreplicatable magic. Compared to Time Modification, which could reverse cause and effect, changing the past, this was merely magecraft of Time Adjustment which could stagnate time passed and accelerate time to come; it was not magecraft of extraordinary difficulty. The only consideration was the size of the bounded
field and the scope of time that needed manipulation.
...
A method that limited the bounded field's scope within the practitioner's body made it easier to establish a Reality Marble. Although it was impossible to completely isolate the flesh from the outside world, it could minimize the effect of the outside world on the body. Within this minimal bounded field, he could manipulate time, a few seconds at a time. This was the magecraft that Emiya Kiritsugu created—Innate Time Control.

Dunno why it calls it a Reality Marble but whatever. Anyway, it's fine, you can unify them with only a little bit of Nasubabble (and a bit more math babble). Just note that "space" is a property of the "World", and that you do have your own World to work with. The area inside the ego boundary - aka your human body - is a place where your inner World and Gaia's World intersect, so it's kind of like a wormhole connecting two universes. But aside from that intersection, it doesn't really make sense to use one universe's coordinates for a location in another - like, trying to give an Earth-based latitude and longitude for a place on Mars.

So you can "address" locations in your body by relating them to your own personal World, which of course is at rest relative to itself. But that only works for locations "inside you" - that coordinate system just doesn't cover anything outside your body. So Kiritsugu's spell is merely difficult, while Araya's mobile ward that targeted an area several meters out from his body is bullshit Origin-enabled "one step below Sorcery."

Well, there's still the weird bit that strictly speaking your arms are moving relative to your center of mass, but I guess you can say that it's like, no matter how a mountain changes, the latitude and longitude of that mountain won't move?

Well, anyway, that's probably way too complicated to ever put in the story but it's a cool thing to work out.

So is this a correct TLDR of what you just said?

  1. Bounded Field with a static location relative to Gaia's World is 'easy' and standard.
  2. Bounded Field that moves around relative to Gaia's World, but is always within the body of a magus, and uses that magus's own Inner World as its frame of reference, is difficult but not unheard of.
  3. Bounded Field that uses a magus's own Inner World as its frame of reference and can also extend beyond that magus's body is HOLYSHITWTFHAX.
 
More than that if I remember this correctly though this may be fanon bounded fields were originally inspired by ego boundaries.

Basically. Actually from my deduction above I'm not even sure 3) is possible, for the same reason that you can't give Earth-based GPS coordinates for Olympos Mons. I really have no idea how Souren did what he did other then some vague "something something Stillness something invariant positions?" spitballing, which is fine -- it's One Step Below Sorcery (TM), after all.
 
I don't think reality marbles are that common to the general mage population.

I think that Magi are said to really dislike Reality Marbles because they're seen as a dead end when it comes to research because you can't pass it down to your descendants so you're just wasting years developing one.

No, they're just concidered dangerous and weird, but we have canonical examples not only of people inheriting Reality Marbles, but of them actually forcing themselves on people to survive their owners destruction. That happened with Nrvnqsr, with his reality marble actually resurrecting Maiko to survive Nrvnqsr's death.

So you can absolutely pass them on/down, at least in the same manner as a Mages Crest. Though I suppose if a future Emiya family wanted to do that they probably would have to make 'it' (where 'it' is the whatever the the reality marble survives in after it's creators death) out of his corpse after he died and integrate 'it' into the family crest.
 
Well, the thing is, Reality Marbles are so intensely personal that it's unlikely in the extreme for that to be possible if they have any useful attributes beyond "pocket dimension." Nrvnqsr's could do it because it was fundamentally "the primordial mud" -- and on an amusing note I just realized that that would make him made of the same stuff as the Chaos Tide and Sakura's Shadows -- but anyway, it's high-end conceptual stuff that's all about "living on, living to evolve, etc etc." And that's purely a coincidence based on the person that Nrvnqsr happened to be, not something that generalizes.

Archer's UBW, for example and on the other hand, is a statement that "My whole life was forging blades without end." Rather than something that forces itself on people, it's something that won't be accepted by anyone whose approach to life is anything but "alone on a hill, forging endless blades." And its standards are very, very high - it didn't even accept HF!Shirou, whose methodology was basically exactly the same but had accepted "another", so that he was no longer "alone." And we all saw what happened as a result. (UBW!Shirou got away with it because he wasn't trying to inherit Archer's Reality Marble, but rather stealing xp to build his own.) Maybe Muramasa could use it, if it was somehow gifted to him. Maybe. Or maybe he'd explode into swords from the inside too.


So like, unless you somehow know in advance it's going to be something that either makes you immortal, or by nature can be passed on, making a Reality Marble is going to be a huge waste of time. By the point that you could ensure that you could pass it on, you've solved the problem of "perfect cloning" and are about half a step from the Third like Touko is. (Well, I suppose there's also the "I can use my Reality Marble to make something that my children can use" option, but again, very niche applicability, and requires you to know it ahead of time.)

Well Diabel's gonna be working himself into the ground working everyone else into the ground due to his (completely justified) paranoia. Just a shame he's off base again.

Good chapter but I kinda of wish we could have seen some more of the other characters and as always a love seen characters learn and display mage craft. I picture the Power of Friends dowsing looks like that friendship sign from yugioh.

One minor correction about continuity, in the first chapter Illya said she wasn't Berserker in the beta but Berserkah since someone else took it even back then.

My understanding of the bits and pieces of translation and summary is that Muramasa forges a Kusanagi tier sword the old fashioned way, but uses the borrowed UBW to make the forging process instant.

Basically, instead of adding a sword to UBW by seeing it, he's adding it to UBW by imagining it in even more complete detail than what Shirou/Archer do when they see a new sword for the first time. Then he just goes ahead and Traces it.
 
This version of Shirou doesn't know UBW anyway, right? (Is it ever made clear if the hypothetical bad-future Shirou eventually known as Archer actually learned UBW while he was alive, or if it's just an extra spell he gets as a heroic spirit? It's thematically appropriate, but not really a natural progression from the other magic he knows.)

Well, at the end of the day, enough of the Nasuverse hangs on intuitive-but-actually-wrong Platonism, that we can't rely on real-world analogues, because it's all wrong anyways.
That's the fun part. Personally, I wish Fate would just go all-in on Hermetic neo-platonism and drop the "power of belief" bits.

(I have a rant stored up about the popularity of "magic works how people think it should, because they think that" and how perfectly un-magical that is, but this is neither the time nor the place.)
 
"Unlimited Blade Works" as in the special move/spell where Archer chants some magic words and then moves himself and some targets in range to a demiplane where his powers work better.

Shrou's possibly-magical memory for sword trivia isn't that.

Shirou's ability to trace swords comes from UBW. UBW is how he traces his weapons. He has had that for a long time.
Materializing a reality marble is the hard part. It would take fate route Shirou 10 years to master the basics and another 10 years to become proficient.
But Shirou always has UBW. Even in Fate Route he has it and thats the route where it will take him years to learn how to use it. Gilgamesh at one point injures Shirou and when Shirou looks down at the wound it is covered in swords and he feels like everything in his body is made of swords.
UBW is a reality marble. It is the basis for Shirou's projections. He may not learn how to materialize it always, but he still has it because it is his soul.

Shirou's 'sword memory' is his soul, which makes him great at all things sword by his nature.

Archer's (or UBW!Shirou's) Unlimited Blade Works is the ability to take that soul, that vision of the world, and impose it over the regular world. Basically, he kicks Gaia's reality to the curve and forces his into being temporarily. As has been said, this is the hard part.

Actually, rather than "power of belief", it's more accurate to consider the entirety of humanity as a Lovecraftian concept-devouring hegemonizing swarm more akin to Yog-Sothoth than anything else, whose interior universe is mostly determined by what concepts it has recently devoured and only mildly by what its component humans believe. It's much more important what humanity understands than what they believe, in other words - belief only really shows up in the form of Phantasms, which honestly are rather well named.

Kirito dodged, leaping backwards, springing off the trunk of a tree and spinning away.

The tree was smashed, blown down by the monster, the thing, that was chasing him.

It was uniformly white, glowing a strange off-blue alabaster color in the moonlight. When he struck it with his sword, it had been as smooth as marble, despite flowing like a mudslide rolling across the land.

The tree he pushed off of was knocked down, cracking loudly as it was broken in half as easily as snapping a splinter between someone's fingers. The great white mass surged forward, pushing trees aside, and the formless blob took on a form. A snarling wolf-like head, with multi-faceted eyes like a beetle, that was probably staring at him.

Also, for some reason, a maid headband was formed out of the same homogenous stuff as the head.

Kirito grimaced, darting forward, his sword glowing as he slashed at it once, twice, three times, carving a triangle with the afterimages of his blows.

He hadn't caught up with the Black Cats yet. He really, really didn't want to think about what that meant.

"Whoa!" He shouted, leaping back as he rolled away from the monster's mass as it simply surged towards him, like an avalanche trying to bury him alive.

Kirito didn't want to call it the main body exactly, but something extruded from the top, like clay being pushed through a mold.

It was a person, more or less. A head with long hair-like tendrils, a featureless face, and another frilly maid headband. The torso was buxom, but the details were obscured by what looked like a frilled apron. Two arms, spread wide, before they came together to clasp like in prayer. The barest suggestion of hips merged into the main mass of the monstrous thing in front of him.

Floating above that fake head was a blood-red rhombus and a monster's name. [The Queen of All Slimes].

It screamed without sound. A simple howl without words, expressed directly into his mind, without passing through the air.

"Gah." Kirito stumbled, trapped by a sudden sense of vertigo. His sword slipped from his fingers. His Circuits, blazing-sharp lines of light within him, became blurred and unsure, washed out and obscured by a strange fog.

His body was melting. No, he realized, as his thoughts thickened and pulled apart. His very self was melting.

The demon rolled forward, covering him over with its mass, smothering him, crushing him, and digesting him.

His body melted into pixels before the damage could add up too much, though.

Kirito considered the firm, smooth hardwood beneath him, pressed against his cheek, arms and body and legs flat against the plane of the ground.

"What the heck was that?" He asked himself.

"Sorry, but brother was just unlucky!" The voice of a cheerful girl rang out, and Kirito raised his head.

It was a familiar scene. The dojo attached to his parents, or rather, his aunt and uncle's house; to his side, it opened onto the yard, with the thing that went donk. In front of him was Sugu, upper body wrapped in a gi, and her legs in a full hakama. Her arms were at her sides, her fists clenched in the guts pose. Then, she thrust one hand up, pointing at him dramatically with her right hand, while her left hand flung out. Between her arms, was a lot of the kind of bouncing that Kirito firmly refused to recognize in his sister.

Behind Sugu was the shrine, with those old swords that Grampa insisted had been in the family since before the Reformation, and above them was a banner proclaiming that [Brother Love is Justice], which didn't have anything to do with Grampa, and everything to do with Sugu. Kirito considered that, and then decided not to think about the implications, for the sake of his sanity.

"It was always a gamble to see what card Yui-chan would decide to play, and unfortunately, rather than re-playing a Character Card from the graveyard using her special field return command, instead she decided to steal a Card that had been slipped into another Duelist's Deck! And that card had a really, really high stat for Special Attack because of all the Monster Fusion and Breeding specials that other Duelist had stacked on that Character Card!" Sugu explained. "On top of that, since you only had yourself in play without any other Character Cards, you totally lost! Maybe next time you should bring a friend, and hope that Yui-chan doesn't draw something quite that crazy!"

Kirito considered that, and then responded. "Sugu." For good measure, he pushed himself off the ground, since staring up at Sugu was giving him a crick in his neck.

"Yes! Oniichan!" Sugu responded, smiling brilliantly.

"I didn't know you ever played trading card games." Kirito responded, frowning.

"Ah!" Sugu blushed, looking down to the side. "Well, you know, there were a couple different Duel Monster card games that were popular during elementary school. I played them with my friends!" Sugu pushed her pointer fingers together, before shyly looking at Kirito through upturned eyes. "So you understand why you never got involved, right?"

"Guh!" Kirito said, staggering back as he clutched at his chest. "I – I had lots of friends during elementary school! It's just that they were all net-friends, so meeting up IRL was really hard!"

"You don't have to lie to Sugu, you know that, right Oniichan?" Sugu said, bottom lip pouting. "Even though you always ate lunch alone outside, even though you always bounced the soccer ball against the wall by yourself during recess, and even when you only ever told stories about what you did in games, Sugu can accept all of that!" Beaming, Sugu spread her arms. "Sugu can embrace everything of Oniichan, even the embarrassing parts!"

"I won't accept it!" Kirito said, fists clenching and shaking. "Even if it's a dead-tree-format analog game, there's no way that an elite gamer like me would ever lose! I'll learn all the rules, master the system, and win using my own style! Even if I only have one Character Card to play or whatever, the cool and reliable Black Swordsman doesn't' go down that easily!"

"That's the self-assured Oniichan that Sugu respects more than anyone!" Sugu cheered, thrusting one fist into the air.

"And besides!" Kirito said, dramatically posing with one hand over his face. "I admit that a [Slime Girl] with a [Maid Outfit] has several hundred [Moe Points], but something like that will lose to [ASUNYAN], the cool big sis maid! With cat ears! And glasses! And knee-high socks! Such a ferocious combo is worth [Moe Points] in the thousands!"

"Mou!" Sugu said, pouting as she shook her hips back and forth. "But what about a little sister that's not actually your little sister! Isn't that the [Ultimate Moe] where love can transcend all?"

Kirito raised a finger in triumph, before playing the ultimate counter attack. "That applies to Ilya too, you know."

"Guh!" It was Sugu's turn to stagger back, one hand reaching back as the other clenched above her prodigious chest. "Just because she's a little sister unrelated by blood doesn't make her comparable to me! Even if you bullied me, that wouldn't unlock a Yandere Bad End! Instead, I would cry, and you would awaken to a new fetish!"

"So go ahead." Sugu continued, smiling radiantly. "Embrace the feelings you keep locked away in your heart, and then embrace Su-"

"No." Kirito said, raising his hand and shaking his head. His instinct as a Gamer were telling him this was leading to a bittersweet ending where a brother and sister wearing trenchcoats got on a train, to start a new life in a new town, where people didn't know why their last names were already the same. He needed to avoid that ending! It wasn't like it would matter since all his friends were on-line anyway so as long as he had internet his social life would be unaffected from moving to that new town, but still!

"There's still a different Card I could play." Kirito announced, smiling devilishly. "I could draw it from the Deck of Friendship, the strongest Character Card with the worst balance! With Attack and Evade stats that look like misprints with an extra digit! If I just use that, then I can win without any tricks!"

"That's my brother!" Sugu cheered. "Even if you always brag about being a strong and cool soloer, you don't hesitate to rely on your friends!"

However, Sugu had put the word [Friends] in air quotes with her fingers.

Kirito collapsed to his hands and knees. "It's not my fault we've never met IRL! It's literally impossible with the setting being what it is! Besides, it's really embarrassing to say stuff like 'oh, we're best friends', even if it's only thinking it in my own mind! A serious student council president wearing glasses! A smarmy playboy with seaweed hair with not-very-hidden self-esteem issues! Compared to that, I'm just some computer otaku! If it was a BL game, then I wouldn't even be the most interesting route!" Kirito paused, hands in his head. "And I'm definitely hanging out with Silica way too much if that's how I'm presenting that."

"Gah!" Sugu staggered back. "Sugu can accept the BL thing, but what's this with introducing another girl's name all of a sudden!?"

"Hm?" Kirito said, glancing up. "Oh, Silica-chan? She's in the guild, she's like… I guess you could say she's the official little sister of the guild? Since Ilya is too disturbing to pull that role off."

"Official Little Sister!" Sugu shouted, suddenly holding a bokken. "I could hold my tongue about Asuna, and your best friend is NTRing Argo away so I'm ready to comfort you, and you never even entered the Liz Route which was good, but now I find out you've been cheating on me with another little sister!"

"Wait, what was that about Argo?" Kirito asked. "I'm pretty sure that's not a real ship-"

"No!" Sugu said, swinging her sword to the side and then raising it to a guard position in front of her. "You don't get to change the subject! Sugu is hurt that Oniichan is cheating, so put up your sword and prepare to take your lumps!"

"Raa!" Sugu roared, tears at the corner of her eyes as she dashed forward, and Kirito shivered unconsciously at the strange resemblance to some strange tiger, his instincts screaming.

And like that, we close the curtains on the strange advice corner, since it was a good place to end, what with the foreshadowing alluding to a crossover next time.

End


I I I

1) I feel like I got about 800 works in, and was like "welp, that's just about the content I wanted to put in there." Then I just ad-libbed non-sense for another thousand words.

2) Originally I was planning on having Tiger crash through the wall, so I could bounce her off these two kids, but that's not how this ended up working.

3) I guess at the end, my biggest concern is that maybe I made these two a little too exaggerated, but it's kind of hard to tell if that can ever really be the case with an omake chapter like this. Like, as long as they're still recognizably the same character, it works? I dunno.

4) I'm going to go back and make sure everything's up to date, but I'll finally push another chapter onto ffnet after what feels like a geologic age. I'd like to pick up writing speed again; we'll see if that happens.
