One of the Four Supreme Planes, Hell!
A purple moon, shaped like a sickle, hung in the night sky, casting an eerie, hazy purple glow over the boundless world below.
Chill and dark.
In the middle of an endless wasteland, a peculiar mountain rose abruptly from the ground.
The mountain was pitch-black and oddly shaped. It did not rise straight up; instead, it looked like a crescent moon standing on the ground, forming a distinctive curved mountain that soared tens of thousands of meters into the air.
It was as if a purple moon hung in the sky and a stone moon stood upon the earth.
In Hell, this curved mountain was known as Crescent Moon Peak.
Aside from the oddly shaped Crescent Moon Peak, the surrounding wasteland stretched as far as the eye could see. Its highest point was less than a third of the mountain's height.
Strange winds blew across the wasteland year-round, howling mournfully. Even divine-level experts were affected by the sound.
Atop the crescent-shaped mountain stood an ancient, mysterious castle several hundred meters tall, its walls a dark teal. From afar, a hazy, unusual aura seemed to shimmer around it.
In the center of the castle was a vast, perfectly flat courtyard paved with a simple, ancient ochre material. Two enormous magic arrays, each a hundred meters across, stood side by side on the courtyard. Their patterns alone were incredibly intricate.
Two burly men stood beside the magic arrays.
Both had bare arms and wore close-fitting armor on their upper bodies, with special, belted trousers below. Strange dark teal marks were emblazoned on their foreheads.
Besides these two armored men, two others dressed the same way were chatting casually by the courtyard. Beyond them stood over a hundred creatures of all kinds. They were Saint-level beings
