Fate/Grand Order Story and Lore (CONTAINS SPOILERS)

[Lily Emilio]

Is there a comprehensive list somewhere of how (we) get to the location of every single Main Chapter, Events and Interludes?

In Part 1 and 1.5 it's 90% done via regular Rayshifting, with a few exceptions of just travelling physically and being transported by BB. I'm curious especially for the methods used in Part 2.

In part 2 prior to the settlement in Wandering Sea, we could not rayshift, and had to dive into the Imsginary Number Space to bypass the Storm Walls surrouding the LBs.
After we settled in (the beginning of LB3), Trismegistus II and Paper Moon was set up so we can do rayshift (ATLAS edition) as I mentioned above. We cannot go as far was we used to with the old method using CHALDEAS and Sheba, cannot go to LBs, and we have more risk and errors during rayshift due to the instability the system has without CHALDEAS being a stabilizer. So other than LBs, we rayshift to all places classified as singularities (main interludes, events and small interludes), we just do rayshift (ATLAS edition). The one place we didn't dive or rayshift was Tunguska where we break through its barrier with the Storm Border.

Sorry for the dumb question, but how does the phase shifting aspect of Rayshifting works exactly? In terms of the concept of course.

To me, the simple way to look at it is to look at Avalon. Avalon is located at the same coordinates of Britain, but it is several "phases" off in term of dimension. You can go there physically through several ways, but normally one cannot reach it, hence the concept of the Avalon (NP) where it basically shields the user from outside interference cuz it made the user temporarily went to a different "phase". Saber is still there, but she's not considered to be "there" until the effect if the NP wore off. So all attacks coming at her will simply not connect at all.

Similarly, for rayshifting, the Master using it is not actually being there at the location, they are in the rayshift coffin at the base, while a construct of spiritron data that is defined as "the Master themselves", being output there. So how can one be there without actually being there? You need to sync the phase of that person's data and the destination, to make the world thinks the person is actually there.

It's basically similar to the idea of teleportation in quantum physics, but in this case magic physics.

Well, we're not entirely sure. In fact, the whole phase-shifting thing in relation to Rayshifting is only mentioned in Melty Blood Back-Alley Nightmare (to my knowledge?), a work that contains many strange secrets.

As for phases themselves, it is the "plane" upon which different worlds lie upon. For example: INS has a different phase. Gudaguda is in a different phase generally speaking. SERAPHIX when it "flips" switches phases, etc, etc. In 4.5, Nemo briefly explains that the "shock" felt when going through the surface boundary (境界面) of phase space is similar to what goes on when they collide with things in INS. Sion also calls CHALDEAS a "sophisticated phase navigation system" in 3.5 (Ooku).

So why I tied "parallel worlds" with "phase" is thus that. Rayshifting apparently works through overcoming phase-differentials, meaning that (as MBBAN mentions) it operates through parallel worlds, not just time-travel.

Gudaguda is in a different phase generally speaking.

Isn't it rather different Universe/Tree of Time separated from panhistory?

[Petrikow]

It is repeatedly described as being from a different phase whenever shenanigans happens. But yes, perhaps things from outside Pan-Human History simply have a different phase? Who knows.

So the act of shifting phases also includes the act of time travel in general?

Like Lily mentions, going to Avalon would also be going through time if not done by physical means.

No, rather, the shifting of phases is separate from 'pure time-travel'. This is exactly the crux of the issue. The fact that Chaldea is utilizing a form of Rayshifting dependent on phase-shifting tells us it isn't as simple as pure time-travel.

[Delastogos]

Also because Time Travel in general is something that can't simply be achieved without True Magic?

[Petrikow]

Well, sort of. Time-travel is possible through a variety of means. It happens all the time in the Nasuverse. The Fifth is more than just time-travel, it's probably closer to the reversion of entropy, or something. It's just that the course of entropy (its inevitable increase) directly correlates with the arrow of time (only moving forward).

The kind of time-travel more generally possible runs into the problem of the Quantum Timelocks. Essentially, there is very little that can be done to actually change history. When something important happens, or at a certain interval, it get compiled into a QTL, thus disallowing time-travelers to interfere with the result. Even if they travelled back to before the QTL, their actions would still end up as the QTL designates. The example Nasu brings up is that even if Artoria used the grail to save Britain, it would still fall, because "Britain falling" is a QTL.

[Delastogos]

I see.

The main doubt right now is how Rayshifting works in Part 2, right?

[Petrikow]

I see.

Partially. The question as to how Rayshifting works in Part 2 comes down to:
Why can Chaldea do Rayshifting without CHALDEAS, if they needed it before and don't have a real replacement?

But there is a deeper mystery as to what the purpose of Rayshifting is. How come this is the method employed instead of more general time-travel? Is it a means of overcoming the QTLs? Or an attempt at such? Was CHALDEAS meant for a different purpose before the Singularities were discovered, and was Rayshifting a part of that?

[Delastogos]

There was the theory going around of Marisbury wanting to create a sort of unified timeline or as others have said, create a new texture upon the old one.

[Comun]

How come this is the method employed instead of more general time-travel?

More general time travel is beyond magecraft's reach. Just because two magics do it as simply side products, doesn't mean it's generally accessible.

It seems possible to send information, even if not physical things. This is what Morgan does, it's what happens in Extella (with Green Hakuno), it's what Lainur in CT2015 does (though, he shoots things into the future, not the past), it's what happens if you dive in and out of INS too recklessly.

I suppose if you define "general time-travel" as "being able to change the present by changing the past", then yes; you need the Fifth Magic. Or you can be Goetia and burn down all of history, that works too, apparently.

Not quite. The process is: Your data is created in the form of spiritron information -> Trismegistus sends it from X point on your timeline (your current location) out of the time axis, where you are momentarily exist in a plane not belong to any timeline basically (a different phase). This is also how Mashu's invul skill works as I said previously. She phases out of the time axis to dodge attacks and go back onto the time axis. So now that your data is out of the time axis, the computer then send it to the desired location, like a RM (Prisma collab), a singularity or even a parallel world (FZ event),...etc. That is why it's a mix of time travel and parallel world travel, but it's neither any of those because what was sent there is just your spiritron data pretending to be something that actually exists on site. You don't physically travel there, you are still sleeping in the rayshift coffin, but you can interact with the world where you are sent to.

I see.

Not that important for me per se. Like I explained earlier, we just used an inferior method of rayshifting compare to what we used in part 1 because both SHEBA and CHALDEAS are frozen with the attack on Chaldea base. We used the method proposed by Atlas Institute to Marisbilly before he came up with his better method of using CHALDEAS as the map. What I am concerned about is the fact that we could travel to the LBs using the old method (implied) but we can't with any of the alternatives. In other words, "us being able to rayshift" is not as important as "us being unable to rayshift to the LBs without the assistance of CHALDEAS" to me. But the alien god did not know we could still go to the LBs and escape by INS diving. INS diving also utilizes similar concept of phase shifting, because INS is a dimension located at the same coordinate with the surface texture layer but on a different plane (different phase), thus we could use it to go into the LB, by using the overlapping coordinates of the INS and the surface layer to determine our destination.

Aren't those examples rather hit and miss?

In general, i think the version everyone assumes how time travel is in fiction is not exactly what happens here.

[Ismail2002]

I have another question since there is a bit of a trend with getting Bronze Servants a role since Atlantis, since Salome has gotten a role in Traum then is who is the Bronze Servant that is going to help us in Nahuil Mictlan or hell is there is going to be a Bronze Servant at all.

[Petrikow]

Nasu has built his fictional universe in such a way as to make time-travel very restricted, yet doable on some levels. You have to let go of your conceptions of "the version everyone assumes".

Clearly Angra Mainyu will solo ORT for us.

[Petrikow]

Clearly Angra Mainyu will solo ORT for us.

He unironically would be an excellent choice to bind together the something from nothingness concept that seems to be at the heart of Part 2...
