Artlu Canyon.
That was a very large canyon located to the west of the Royal Capital.
Inside the canyon was a world of demons, inhabited by a vast variety of them, with generally high levels. The deeper one ventured, the higher the levels of the demons became. This turned the place into a treasure ground for many high-level adventurer teams, but also the final resting place of countless renowned adventurers. Hence, it had earned the nickname "Death Canyon."
It was said that at the deepest part of the canyon, there lay a large Magic Source.
This Magic Source was occupied by a terrifying Level 90 demon who had claimed it for a solid four hundred years. The demon was considered the lord of this canyon, and even the Kingdom found it difficult to chew up this tough bone due to the terrain, allowing the fearsome creature to continue its unchallenged reign.
