However, it doesn't mean planes, they're both focusing on Realms, you're the one who's trying to disconnect them by using improper terminology.
I've explained why they're connected, and that's due to their terminology, as you're the one who's saying they're not talking about the same thing, you'll have to prove that yourself.
It's obviously not guess work, they're both literally talking about the same things, Realms.
>Furthermore, you have to prove that this Myth is indeed true in-universe, since the very Scan say that it is but one out of many theories explaining the origins of the setting.
Well, you won't, as everything in a tabletop game is theory, as it's always up to the Storyteller, that's what the books always say: "This book is not a ruleset, but recommendations"
And by the fact it's a theory, meaning someone theorized it, it exists within the Vulgate.
>Even then, the Scan is explicitly referring to the material Universe, and describing Space and Dimension as physical constrants and properties, it does not at all state that the very concepts of Dimension and Space-Time at all levels were created by the Angels, which goes back to my explanation above.
Well, they are? Are they not? Dimensions are physical properties. And it saying Universe doesn't matter, it's an irrelevent point, because during that time, all things were possible, infinite possibility was true, and the Tellurian is the purest example of this.
>Even then, a Concept doesn't necessarily have to govern what they connote at all possible levels, in most cases they simply influence and encompass reality up to the defined scale of the setting itself, and lacking isn't the same thing as transcending, so 1-A would apply only to God from what I am seeing.
I know lacking isn't the same as having, however, God is stated to be so transcendant over the verse that they couldn't created the verse, as they'd destroy the very concept of Existence due to how powerful they are.
There are many occasions that The One Giver is stated to be transcendant over the verse.
Why does this matter? Well, because all concepts are contained with the Epiphanies, and thus, being transcendant over the Tellurian would mean they're transcendant over the Epiphanies, which would contain this Concept as a Platonic concept, and that's a low ball, a High ball would be it being apart of the Nigh-Infinite Platonic truths of the Supernal.
