(MC POV)
At first, I thought it might be a teleportation Technique of some sort. But since I didn't feel the telltale signs of Space Quarks activating, it must have been something else instead.
An illusion perhaps?
No, I have defenses against illusions so this would not have affected me if that was the case. Unless this illusion could fool even ancient dragons which I doubt that to be the case here.
I recall that there were traces of Astral Quarks present in that Technique, so there's a possibility that we were not teleported to another physical location but instead, had our consciousness pulled to an incorporeal plane of existence.
If that's the case, this is basically an imaginary world that only exists temporarily, any damage dealt and received here would also be negated once you leave it since it's not a physical world. I'm actually quite surprised that the Bei Royal Family had access to a Technique like this.
