Yeah, I was considering to bow out of this conversation, but there were a few things I didn't properly address earlier, and with each adjacent world or SE.RA.PH being declared multiversal now, it's even more silly.
Let's lay some foundations, start with the basics. First Quantum-Time-Lock is a universal event as we can see from Extella materials.
This universe permits the birth of unlimited possibilities, numerous adjacent worlds, and divergent developments of history.
It is mainly concerned with the energy or lifespan of the universe that holds these parallel worlds.
However, as the unrestricted propagation of this process would exhaust the lifespan of the universe, at set intervals, those extraneous worldsroutes (õ©ûþòî Òâ½Òâ╝Òâê, sekairu-to?) removed of the category of "routes characterized by survivability and stability" are culled (õ╝ɵÄí, basai, lit. "cull" / "prune"), so as to prevent the needless expenditure of energy.
These adjacent/parallel worlds are not entire universes unto themselves. Else they would have their own QTL. If you check the beginning of Altera's route (Localization), you will see Parallel worlds defined as "other versions of Earth and its surroundings":
"Earth scientists have hypothesized the so-called 'parallel worlds,' other versions of Earth and its surroundings, expanding indefinitely like mirrored reflections. If true, that would mean that Earth has not only one future, but many. In other words ..."
Then in the non-Localized version it is translated like this:
The World is not one; rather, like a reflection in a pair of opposing mirrors, it infinitely unfolds. Consequently, there cannot exist only a single future -- or so it's thought. In other words --
Which can be cross-confirmed via Camelot that
The World has many layers like an Onion.
There is a theory that our world — the human world — is nothing more than one of the textured layers that wrap the surface of the planet, like a carpet.
These parallel worlds exist unto
The World itself, which appears to be a macrocosm. Just like the Moon Cell that represents a conceptual universe. The adjacent worlds however, are evidently not universes since their pruning starts at the level of a solar system:
It's a very rough estimation, but should the Earth persist at its present level of civilization for another century, it's likely that the Solar System will collapse.
As these laws exist in the layers of the World, they are only concerned with the possibilities brought forth by humanity. The old mages called the laws Foundation of Humanity based on the Human Order, the principle under which Alaya operates that "humanity must exist for as long as possible." It doesn't care for much else.
And to ensure humanity survives, the one doing pruning is also the World itself:
To a certain extent, the existence known as the World (õ©ûþòîÒü¿ÒüäÒüåÞÇà, Sekai to Iu Mono, lit. "the thing called the World") conducts an audit (þÁ▒Þ¿ê, toukei) of timeline survivability (ÚÇ▓ÒéÇÒü¿ÕÅ»Þ⢵Ǻ, susumu to kanousei, lit. "advance and potential"),
Coming to the Moon Cell now, those parallel world are stored by observing the Foundation of Humanity itself:
The Moon Cell is, in a manner of speaking, an eye that observes the Earth.
A processor that faithfully simulates all life on Earth and is capable of providing a definite prediction of the future.
A database of humanity. A massive memory recording their habits, history, ideas, even their souls. Originally it was an observation device left behind by an alien civilization. It had only recorded the nature of life on Earth, but after many years it came to possess its current abilities. - Fate/EXTRA material - Encyclopedia: Moon Cell [Circumstances], p.212-213
'
And so, there is a set time frame in which these branches are trimmed, extra possibilities are removed, and future histories, once fluid, turn to stone. The mages of the old world called this time frame 'the Foundation of Humanity. Such laws apply to the Moon Cell as well. The Moon Cell is a self-upgrading observatory, which continues to record every incident and possibility on Earth. ' - Fate Extella Altera route prologue (Localization).
The spiriton worlds in the Moon Cell are the same. They are not singlehandedly worth multiverses based only on the word "parallel world" that you seem to be doing.
Regarding the scans, I will only address a few because I feel it's unnecessary after making the main point.
3. As it does not threaten the limited energy scarcity of the Universe, the main branch is not infinite.
4. It's more like Humanity just dies there, or some catastrophe hits them.
5. SE.RA.PH is a compilation of Reality Marbles that mimic the Earth, but it also takes inspiration from others. This is just talking about the design and values. Last Encore scripts makes it conceptual planet at most, hence the poster was also a planet. It's why you see that one Earth-like planet lot in CCC.
13. You're confusing Imaginary Number Space as an element with the dimension on the Far side. What BB did is not much different from what Sakura did, only at a bigger
scale
15. This seems contradictory. Whether this is used to scale the Moon Cell, I don't think that's reliable as this supposed to be out of the Moon Cell's reach and by extension, that one character who merged with it.
21. No disagreements besides just two points. I'm also saying the Moon Cell does its own QTL on spiriton worlds like the World. However, I am actually using the scales given while you seem to be just trying to make the cyberworld as large as possible.
