South of the center of the Western Starfield, precisely 1.98 billion kilometers away, stood a mountain named Inkstone.
Within the mountain lay a hidden valley, and in that valley, there was a deep, emerald-green pool whose depths were unfathomable.
At times, malevolent spirits wandered through the area, their forms resembling drifting smoke, dispersing upon contact.
The valley's walls were made of jagged rocks, interlocking like the teeth of a beast, and ancient trees towered overhead, their dense foliage blocking out the sun.
Beside the pool, there was a stone platform with an ancient script carved upon it, which read: "The Place of Fallen Evil, Only the Adept May Enter."
This place was rarely visited, even by those passing by who often soared through the skies outside the mountain, careful not to intrude.
