I've meant this from the beginning
I see, I misunderstood your earlier comment then, sorry 'bout that
I'm just, not sure if the phrase "countless worlds" refers to "countless dimensions" or space-time continuums branching off into timelines like "cardinal universe". You might need to look at the kanji used.
we already have statements implying infinite timelines, and those were dimensions that bordered Lab, so its prolly Self-enclosed worlds, or what you are calling "Dimensions"
but I checked anyways, the kanji is
別次元世界, which means Other-Dimensional Worlds
This kanji refers to "Other Worlds"/self-enclosed worlds at multiple instances in Volume 17
ヴェルグリンドは、幾つもの出会いと別れを繰り返す。そんな中、ヴェルグリンドが理解したのは、ヴェルダナーヴァが生み出した世界は一つではない、という事実だ。それこそ、数多の世界があった。
Vergrind has had many encounters and partings. Through these encounters, Vergrind came to understand that there was more than one world created by Veldanava. There were numerous worlds.
同一世界は一つであり、並列世界パラレルワールドなど存在しない。だがしかし、別次元世界アナザーワールドは存在しているのである。〝異世界人〟がいたので、その事実は把握していた。しかし、これほどまでに多様な世界があるなどと、ヴェルグリンドは想像すらしていなかった。
A single world is unique, and there is no such thing as parallel worlds. However, there do exist other worlds in alternate dimensions. I was aware of this fact because there were “otherworldly people. However, Vergrind had never imagined that there were so many different worlds.
Note : There exist no "Parallel Worlds", but thats referring to "Parallel Worlds" of the "Other Worlds"[aka the hypertimelines], because a "World"[Like the "Cardinal
World"] is unique, so it as a whole hypertimeline does not have branching timelines of its entire hypertime, but that does not contradict the "Cardinal World"[hypertimeline] from containing the infinite and branching timelines/universes[like "universe" of the cardinal world that feldway destroyed].
ヴェルグリンドの記憶通りなら、その父親がルドラの〝魂〟の欠片の所有者だった。名前をローラン・ヘイズと言って、青年時代から大往生するまで連れ添った間柄だったのだ。他にも気になる点は多いのだが、そうした事柄はちゃんと調べておく必要があった。同一世界線上ならば間違いなく、同一国家、同一人物だと断定出来るのだが、別次元世界アナザーワールドには似通った世界があるからだ。世界の成り立ちや法則に明確な差異があるから、並列世界パラレルワールドではないと断定されるのだが、名前なんかは何故か似通ったりしていた
If Vergrind remembers correctly, his father was the owner of the piece of Rudra's “soul”. His name was Laurent Hayes, and he had been Rudra's companion from the time of his youth until his death. There were many other points of interest, but I had to check them out. If they were on the same world line, we would definitely be able to determine that they are the same nation and the same person, but this is because there is are similar world in the other dimensions. Because there are clear differences in the formation and laws of each world, it can be determined that they are not parallel worlds, but for some reason, their names are similar.
The Kanji for parallel Worlds in the last line is
並列世界, which is the same kanji used for "Parallel Worlds/Universes" in Volume 11 in context to "branching timelines/universes". Though that itself is made clear by the fact that they mention parallel worlds and different worlds in the same para but AND with different Kanjis.
Note that, here "
World-line" is referring to the hypertimeline overarching the infinite timelines/universes. The context is that Velgrynd would be able to determine if they were the person was the same identity but from
different branching timelines under the same world-line, like different chloes, but that was not the case since they were not in that "World-line", and instead in "Other Worlds" from different dimensions.
This "World-line" thing is actually used by the author in WN as well, when he referenced Steins; Gate analogies in his author note
I searched a bit, and from what the info I gathered, the "contradictions cannot exist" is equally true for the web novel, and whenever Chloe travelled back in time, it was another timeline so to not make contradictions, meanwhile, however,
the future of those timelines were pre-determined so Chloe always failed, but this one time, Chloe travelled in the Hypertimeline instead, aka the "World" 's timeline[the same world was destroyed later in Chapter 248, and in the same chapter it was also stated that chloe wouldnt be able to time travel again due to the entire world getting destroyed as well] due to acquiring Yog Sothoth instead[aka travelled through the timeline of the multiverse, the GS of time, and not the individual timeline of each universe].
