This is, what's known as the "World Exterior".
But at this moment.
The unbreakable rules of several eras have been shaken.
The Sacred Spear that anchors the world, the Anchor of Storms connecting the world interior and exterior, the Tower at the End of the World.
When the anchor is lifted, even the laws of the plane itself can be broken through.
Crack——
Crack.
Amid the crystal walls of space, those crystalline cracks become more prominent.
Then, in a certain moment, they shatter completely.
Transforming into——a vortex that devours everything.
The vortex is endlessly pitch-black, infinitely profound.
Like a black hole, it devours light and seems to connect to another deep and mysterious foreign space.
That is, contrary to the "World Exterior" connecting the Main Material Plane and the Astral Realm, the space beneath the foundation of the Main Material Plane.
If it were to be named, then describing it as "World Interior" might be more appropriate.
