1. You need to show proof that genshin’s universe is refering to the real space of the tree
2. Whatever ur talking abt no one reaching the tree has like no meaning here unless ur talking abt genshin mfs
Just dimensional travel
I don’t need to prove it, because the nature of the True Universe itself reflects IT. In Genshin, there are two universes that oppose each other. This is very similar to the case in Honkai Impact 3rd, which explains that IT and SoQ are constantly trying to overcome one another.
The True Universe is also the place of origin of the dragons before Phanes separated it with the eggshell. Meanwhile, the Dark Universe is the Abyss / Void Realm. These two universes have been in opposition since the beginning. That is why the Abyss was able to invade the True Universe, which led to its destruction, and why elemental power can destroy Abyssal energy.
You yourself mentioned that Otto once saw Dvalin, which implies that the dragons’ planet indeed exists within IT. What I am referring to here is the universe where that planet exists.
IT is only an analogy used to explain a universe. This is even explained in HSR.
The Imaginary Tree is a theory of the universe widely accepted by the modern scientific community.
And each leaf is merely a representation of a civilization.
The worlds are separated from each other just as leaves are separated by air, between which are unknown imaginary domains that are nigh impossible to traverse.
What I mean is that a leaf is simply an expression used to describe a civilization or a world. That is what Teyvat is one of the leaves on the Imaginary Tree (IT). However, the True Universe is not the same as a leaf, because there are countless worlds that exist within the Genshin universe.
Characters like Octavia and Surtalogi have already traveled across other civilizations, which implies that every civilization or world they visited represents a different leaf.
This means that Teyvat and the thousands of civilizations or worlds they visited are already different leaves, which implies that they have crossed the Imaginary Barrier, since the Imaginary Barrier is the boundary between one world and another.
Therefore, the True Universe is not merely a leaf, but rather a cosmological structure far larger than a single leaf.
