Gray Kingdom—Sharnoth
This independent world formed through the Supreme Deed was not the "ellipsoidal" shape understood in conventional terms.
On the Earth Surface, one could walk along a straight line and eventually return to the starting point.
But the Gray Kingdom had no such arrangement. Walking in a straight line would only lead deeper into the world...
It could be understood as being "strip-shaped."
The entrance was its beginning.
The capital was situated in the middle.
If one passed through the capital and continued deeper, one would enter a region filled with danger and the unknown, eventually reaching Sharnoth's World's End.
According to Sharnoth's regulations,
the central area where the capital stood was more like a boundary. Without permission, no one was allowed to cross the "capital line" into the deeper regions.
The Faceless Ones usually referred to the area beyond the capital as the irrational zone.
Rumor had it that all kinds of Faceless Ones who could no longer suppress their madness wandered in its depths, along with some aberrations that could scarcely even be called Other Demons.
Any Faceless One who trespassed there usually never returned.
At present,
at the deepest point of the irrational zone—the World's End of the Gray Kingdom—stood a massive spiraling gray mountain.
Only a single cave entrance was hidden within it.
The entrance was isolated and sealed by a stone door bearing seals personally set by Gray.
Even the entire spiraling gray mountain was constructed from piled-up sealing materials.
Its sole purpose was to suppress an existence so dangerous that even Gray himself could not control it.
If the stone door were opened, one could venture deeper through the profound, chaotic cave tunnels
filled with Mad Whispers.
After successively deciphering the spacetime traps laid throughout the caves, one would eventually reach a secret
