Hereafter [Worm x Fate/Grand Order]

[Windborne]

I'm not sure whether I want them to eventually get along or not. On the one hand, having Taylor and Fou at odds reduces Taylor's Sue meter at least a little (because any character at the end of their original story is going to ping parts of the Sue meter by their very nature when they're the protagonist at the start of a completely different narrative), but on the other, it might be meaningful to have them eventually get over their misgivings for the sake of Chaldea, the twins, and the mission to save humanity.

I'm sure they'll bond over their mutual irritation with Merlin at the very least, and latest. I mean Merlin just pisses off everyone except Ritsuka it seems like. I can't imagine Merlin not shoving his feet into his mouth around Taylor and getting decked by her for sexual harassment at least once. Though I imagine she'd end up treating him like Alec (Regent) in the end, they're both essentially sociopaths who try to do right by those they care about, albeit failing most of the time.

Salter can kill Herk. Granted, she does it by shouting "EXCALIBUR!" until all of his lives are gone, but she can kill Herk. This one is powered not just by Fuyuki's Grail, but also by the Grail Lev gave her. She has enough magical energy to say "fuck you" to basically everything

That's why Goddess Rhongo didn't have the Grail in her Singularity. If she had that kind of power backing her up she'd be able to fire off intercontinental ballistic Rhongo beams every 3 seconds and that'd be GG for everybody involved real soon if they don't have an army of Arash clones to keep Stella-ing them out of the air.

Regarding Olga:

Spoiler

I doubt there's anything that Taylor could do to keep Olga around, but when I got to thinking about it, I came up with something that would be in character for her. Killing Olga. If she can't save her, she can at least spare her an eternity of torment by ordering Cu to destroy her soul, or something.

Well... I can think of tbh is...

Spoiler

I forgot when did Da Vinci started making her spare body but I would think that could be of use as a temp. measure, though Fawkes could use his author privelage to make it being ready and done for an emergency operation and barely enough until they have a much better body for her or modify said body to be more perfectly fit on her.

Other that that I got some weird ideas but it might be a bit... too much of a stretch or too dangerous, though if they manage to bring Cu around having another caster and a druid at that might give them a much higher chance.

 

[buli-buli]

I had a completely different idea regarding Olga Marie.

Spoiler

In her End, Olga Marie is betrayed by the only person she ever unconditionally trusted and the only source of positive reinforcement she's ever had in her life. She is forced to realize she is alone and has always been alone. She acknowledges she has accomplished nothing of value in her life and now she never will. She is reduced to a sobbing, screaming mess who begs for anyone to save her even as she knows no one can or will. She is fully aware she is doomed to a horrible and painful fate.

If that is not a damn Trigger Event then nothing is.

The only question is whether Taylor's Passenger can still bud off of her despite her lobotomy. (I imagine any theoretical changes to Olga's psyche caused by Taylor's presence won't be enough to bring her past the range of a second-generation trigger).

>Olga triggers with a QA bud that allows her to make and control shadow servants or Grail Mud-esque servants

Or fuck it, bring over one of them Shards from Ward whose owner no longer needs it.

 

[V01DRei]

I did a calc a while back about how much energy (in joules) the Fuyuki Grail has, and it turned out to be...not as much as I expected. IIRC, I took the line about how the Fuyuki Grail had enough magical energy to fuel an entire department at the Clocktower for a year and went, "Well, how much energy does CERN use up in a year?" It was less than I expected.

hold on, they were talking about the Magus Clocktower… so I'd say double that calculation, at the very least…

To quote the banner that you should have seen if you started the thread from page 1:

Gold Morning was supposed to be the end. The capstone of a short, frenetic career. Taylor Hebert's fight was supposed to be over. But the end of one story is often the beginning of another, and when she's offered the chance to take part in a mission whose scale and scope feel so very familiar, there's only one answer she could give.

Click to shrink...

In addition, a quote of the entire first post.

Yes, now we see the new project I've been working on for the past two months. This is Hereafter, a story much different from An Essence of Silver and Steel, because this is most certainly a baseline Taylor, and she will not be doing any great and grand superhuman feats with the power of Heroic Spirits.

Still around? Okay.

What You Need to Know: Every part of Worm up to, but not including, "Interlude: End" is canon to this story. The whole shebang. The Undersiders, robbing the bank, the Bakuda thing, Coil, the Travelers, killing Alexandria — everything, including Gold Morning. This is a Post Gold Morning story, only instead of being dumped on an alternate Earth with her dad and retiring, Taylor was handed over to Chaldea, and it probably wasn't the healthiest lateral move after saving the world to be thrust into an organization that, you know, is dedicated to the same thing. For Fate/Grand Order itself, I'm expanding things a little so that "Fujimaru Ritsuka" is "Fujimaru Ritsuka and Fujimaru Rika," so that I can inject some humor into the story without Ritsuka appearing bipolar or silly. The rest of it is all as it was in canon. Taylor is technically taking the spot of another "canonical" Master, but only in the sense that there was an unnamed Master Candidate 9 in Chaldea who existed solely to be a statistic and that spot is now Taylor's.

I'm not afraid to deviate from canon, where it needs to happen, but having said that, the Singularities should be familiar to you, because Taylor isn't going to make Goetia deviate from his plans drastically enough to matter.

So far, the plan is only to do part one of FGO, "Observer on the Timeless Temple." That's already going to bring us north of 400,000 words, if the word count of Singularity F is any indication of each Singularity's length. I wouldn't be surprised if it's significantly longer. "Cosmos in the Lostbelt" is too much to commit to, right now, in no small part because that storyline is still ongoing, so I have no plans for it.

What This Story is Not: a power fantasy. Taylor will not trample over all the peons, magically defeat even Servants with her mad skills, and master magecraft in two years that took Clocktower prodigies whole lifetimes (or generations) to perfect. If you're expecting her to steamroll everyone, you've come to the wrong place. I told you already, didn't I? This isn't going to resemble An Essence of Silver and Steel much at all. Welcome aboard the strugglebus.

Well, kinda. Taylor's grit, determination, and cleverness will continue to be her best weapons, and it's an uphill battle, but Nasu's the one who wrote FGO that way, not me.

This is also not a romance story. Seriously. Don't be surprised if Mash and Ritsuka wind up sweet on each other, and the usual Servants who are utterly infatuated will still be utterly infatuated, and there might even be some flirting (Cu is a horny dog) and some female gaze (because Taylor's surrounded by super attractive people, let's be real), but romance isn't anywhere in the plans.

Click to shrink...

Taylor is a character from Worm, which is a somewhat popular piece of webfiction amongst some parts of the SV community. The author also said in the first post in the thread that the singularities themselves would not have major differences, and that Taylor's presence wouldn't majorly derail Goetia's plans. In addition, the story as posted here so far hasn't deviated from canon, but it's also not past the end of the first singularity yet. So maybe give it a bit more time to get through what could reasonably be called the tutorial level of Fate/Grand Order before expecting major divergence from canon.

Edit: The edits to this were fixing my lapse of competence with BB Code tags that resulted in nested quotes where they were not supposed to be. Pray forgive my failure.

Click to shrink...

That's the difficulty with a FGO story: if you change too much, it's not a FGO story. To be a FGO story, taking place during canon instead of outside of it, the Singularities have to be unmoored points in history held in place by a Holy Grail. No matter how much you swap around the cast, the core plot remains the same, so the more things change, the more they stay the same.

Also, see above.

I do have some curveballs to throw later on. But Fuyuki is very much the most linear part of the story. It's the tutorial level in canon for a reason.

I can't do like Blinktwice, if you're thinking about that. He started throwing around endgame, hard mode, Lostbelt level stuff from the word "go," and, uh, none of the characters here would survive that. At all. Taylor got forcibly set back to level 5, and the rest of the team is starting out at level 1. If I started throwing out Divine Spirits and Beasts of Disaster in Fuyuki, they'd all get murked. Instantly.

Somebody suggested her Triggering as a solution. I think it is a neat idea. The stressors certainly indicate a Master, Breaker (sub: Mover, Stranger) power which QA could provide. It wouldn't be shadow Servants as that doesn't at all address the part of her problem that is "I don't have a living body to return to," and Shards generally don't hand out powers to people that are 100% guaranteed to be dead within the next ten minutes even with that power. My guess is that her power renders her as a near invisible cloud of electromagnetic distortion that possesses nearby nervous systems. Or in other words, it makes her a ghost. Once she goes back to Chaldea she can just offload herself from Taylor, Mash, and the Gudas' left arms and control a familiar(s) body(ies). Da Vinci should be able to eventually cook something more permanent up.

I was meant on saying the scenario to happen that would not make Olga do the panicky stupid by running to Lev, and by extension running from Mash's and Ritsuka Fujimaru's protection which has highly difference here than in canon.

There's two Fujimarus in story and seeing Gudako is a bit more perspective than Gudako, she can instantly possibly act out and grab Olga from not running. Or Taylor who is more experienced and would quickly come up in a conclusion why the sabotage(and who the turncoat is) and grab her.

And if Lev. regardless would attempt to nab. Olga and yeet her to CHALDEAS, presenting exhibit A on CasCu's solution, Primordial Runes.

Its a literal hax of a form of magecraft especially in its applications & being possibly an Authority or borderline of one that a Mystery that made Olga freeze & slowly drag her to CHALDEAS using a Grail's upkeep. If that does not work? There's Command Seals to juice up said magecraft more ignoring on the implications on who CasCu really is in LB6.

Even then, CasCu is a druid of high skill & knowledge, transference of spirit from one thing to another is one and state ability notable in such spiritual practitioners. Stabilizing her is imperative anyways & giving her a spiritual equivalent of a coma is something possible and in a safe container until she is transfered to a suitable body.

Uhhh... how would that even work?

First, unlike Mash, Fou, the twins and Taylor, Olga's body did not survive and thus, did not get converted into Spiritrons and yeeted to the Singularity, only her soul which the Entities does not parse and add as a variable because they work in conventional science?

Secondly, a Singularity is a knot in the Human Order, while Shards such as Phir Se's and Contessa's have notable examples of time travel, theirs are a bit more linear if I remember and as Entities work in multidimensional parallel realities and not alternate ones, how would they even attach to someone on a Singularity which works almost in an alternate world with a much looser base?

Third and lastly, Olga's clinically dead, no body and she's just a spiritron entity walking around because of the Singularity exerting its unique(loose) laws and Chaldea using its equipment and observational devices that makes the spiritron entity that is Olga Marie exist in both the Singularity and Chaldea's reality insists she is existing and not fizz out, or any ways(horrible ones) to die and vanish?

well, powers can be granted to people in other universes than earth bet, it's just rarer and they tend to be less potent. And during the year they've travelled back to, the shards were doing their thing on earth bet, having arrived in 1982 or something. So theoretically a shard could cause someone to trigger, now whether a spiritron body is enough is a good question, shards seem to have genetic detectors to target their hosts, but sometimes the host isn't biological and still gets a powers, see dragon for instance, in ward there is also a dog that triggers but it's from a broken shard and we see it specifically triggers cause it had some human words pass through its head at the right point in time, meaning it's likely also linked to being human in mind. So now that we know that non biological beings can trigger and that the main requirement is having a human mind. I'd argue she might be able to trigger. Still unlikely though..

I think the second point and third point(time shenanigans) are the strongest, but I don't know if the first works fully for your argument. We just don't know if shards can adapt to trigger souls or have to deal with magecraft etc., because in canon they were never an issue. We know shards can trigger AIs and Nilbog's creatures, so what is to say they can attach to something fairly looking like a human? A lot of case 53s didn't have human bodies, and the same can be said for some changers and especially breakers.

Listen, if Dragon can do it anybody can.
In the Singularity Olga has a pseudobody or she would otherwise disperse as a soul. That would be something QA could connect to, and once that happens QA could maintain Olga's anchor to the World while using her power until she could possess and properly settle a suitable replacement body.
One doesn't need Heavens Feel to transfer souls, one just needs to have a vessel, a means to effect the transfer, and the skill to not fuck it up and/or die in the process. Think of Orlocke from Case Files. Between QA preserving Olga as a living phenomenon (*TATARI intensifies*), and Da Vinci (certified nigh omnipotent genius) it's just a question of how fucked up Olga will be mentally from the whole ordeal (some Breakers are generally discouraged by their Shard from staying in their changed state for too long. How long and the form of discouragement vary from Shard to Shard and power to power, but they can be anything from the state being mentally and/or physically harder to hold as time goes by, to increasingly unpleasant as time goes by, to paying a price that scales to time spent changed, and you know the standard human trauma response that is so often conflated with Shard behavioral interjection).

To be fair that is really the shards working in their hosts best interests. Staying in a breaker state for long periods of time tends to result in bleedover from the shard to the human, something most would avoid if they knew it was a thing.

Parallel realities/worlds fam, the Entities work if I remember correctly through a multidimensional way on a singular base and template of reality.

Cause they would had started t-posing for dominance or died in a ditch crying blood for more eyes if they dabbled on alternate realities in all the worlds they experimented on has its fundamental laws being different from the common and mundane reality they work with fundamentally.

They picked a mundane planet Earth as a basis when they pick said planet as their destination during the last stage of their cycle and when they arrived, made use of divergent parallel worlds with near empty/empty parallel worlds to house their shards and poked around on the sapients through Shard connections of different parallel Earths with certain divergence based on the parameters each Shard works in.

It is when they leave off world that their use of cracking the planet and leaving no traces of their tamperings their work affect in multiple realities due to the sheer damage they would work destroying that exact equated amount of destroyed Earths Wibbles/someone pointed out in if I remember correctly.

It is in theory possible even why Taylor is in Nasuverse, if the reasoning Fawkes made use of in sending her aside from supernatural means is through Contessa dumping her dying body through some fucked up space-time chaotic fuckery nearby that appeared on wake of Zion's death that her Path decided to yeet on the exact time and space where Taylor will not affect them anymore thinking it will be going to erase her body or drop it to a much deeper corner of reality where she ain't going to be a factor anymore.

We just don't know if shards can adapt to trigger souls or have to deal with magecraft etc., because in canon they were never an issue.

Click to shrink...

They technically have no souls in a factor when the Entities actually operates and uses mundane science and not actual supernatural stuff, just hyper advanced enough and using a sapient host as a transmitter and user of whatever fuckery the Shard wants to get off to that the streamlined it enough that super science acts like magic and all that.

Heck it is pointed out even, the Shard Space, the equivalent of an afterlife and percievable reality of the Shard Network uses the data gathered of the Shards to make simulacrum images and memories of their hosts akin to a psuedo afterlife of the parahumans.

Which, I'd like to point out that Dragon is an AI and is possible through mundane science alongside the Entities have records of encountering AIs, possibly even made by a civ.'s own innovations and knowledge even so they have data points on that.

The Nilbolg critters & C53 are even similar cases, their sapients, the changes/creations are Entities made regardless if the culprit is a demented parahuman in perpetual god complex crack, or mad science gone wrongly correct.

Souls, and supernatural shennanigans in the other hand are new variables without old datapoints the Entities can gather on given as I pointed above, they worked through mundane science in multidimensional crack cannonically.

Its even highly debatable for QA to bud when the possibility of multiple damages, lack of energy(lifespan) due to extensive use or even whatever accidental or purposed damages the ones who artificially induced a third trigger during Gold Morning.

And it is even too questionable how long Queenie had needed to recover to fix its issues it had gotten in Gold Morning and how(and how long) it would find Taylor when its equivalent of real time coordinates and GPS on her got the double tap surgical shots courtecy of Contessa.

 

[Tzardok]

You make a lot of assumptions that don't necessary hold. Taylor was sent to the FGO world through shard means. That means that we are not dealing with two multiverses with different laws of nature, but a single one. In other words, the Entities are in this fic Nasuverse aliens and just as magical as Sefar or the Olympians or the other aliens that came to Earth. Unless spiritons are a unique Earth phenomenon (what they aren't, canonically) the Entities have already encountered them and know how to deal with them.

 

[The-Chained-One]

I don't think that dragon and nilbog creatures are valid candidates only cause the entities have encountered them before. To a shard I don't think it matters if a body is made of magic, as long as the mind is human, especially considering that her body, while made up of spiritrons probably, still functions like a normal body. Also yeah, a lot of presumptions on what entities are like here, taken as fact when they're really just theories my dude.

 

[buli-buli]

Okay... since I'm the one who brought up the Trigger theory I'll give some more of my thoughts.

First off, no one seems to disagree that Olga Marie's canon fate is Trigger Event worthy. So let's move on.

Aside from a Trigger Event itself, a person (or sapient being or whatever) needs to already have a connection with a Passenger/Agent/Shard, normally evidenced by the presence of a Corona Pollenta (no idea how this works in the case of AIs or other beings lacking a physical brain). Shards look for Hosts they believe have a high probability of Triggering. QA moved from Taylor's dad to her for example. Now, Aiden Tate is proof it doesn't take much for a Shard to bud. Neither he nor Taylor had any notable or memorable interaction with each other aside from relative physical proximity for a couple of months. Taylor has spent up to three years as Olga Marie's subordinate. And Olga Marie is just a bundle of neuroses and complexes. Far more than enough time, proximity, and cause for Olga Marie to receive a bud of Taylor's Passenger and gain a Corona Pollentia. The real question is whether or not it's even physically possible for Taylor's Passenger to bud given her Corona Pollentia and Gemma were destroyed, cutting her off from her Passenger. But, if it is possible, I do not see why being turned into an astral projection would mean Olga Marie could no longer Trigger. Dragon is proof enough that the physical brain is not necessary to Trigger. And the bud would be proof in itself the physical connection is unnecessary for Shard-Human interaction.

TL;DR
It all comes down to whether or not Taylor's Passenger still has enough of a connection to her to bud to people around her. If it can, then a physical Corona Pollentia is not necessary for Shard/Human interaction, and thus, not having a true physical body is not an impediment to Olga Marie Triggering. If it cannot, then Olga Marie never had the potential to Trigger in the first place.

There's also the question of how that'd work through the time travel, cause unlike the rest, she got actually yeeted back, would her shard connection, assuming she had one, follow somehow? Is there some active connection the shard could ride along to stay connected to its host in the past? It's why I suggested she might just catch the attention of a shard from 2004, I think that's when singularity F is, and then trigger with that.
