There are four types of supernatural structures in this world.
Dungeons. A place where one or more types of monster communities reside, all under a colony leader and a dungeon ruler.
They are the most loved structures of any adventurer party or guild.
They occur naturally and the monsters inside this structure steadily and quickly regenerates, making it a good place to collect, gather, and research materials of a different kind.
After that comes Labyrinths. A complicated maze-like structure that could have multiple strong creatures on the level of dungeon rulers as well as countless weaker creatures.
The area coverage of this kind of natural structure is mostly very large and could be as big as the coverage of a few cities.
The climates inside these labyrinths could be very different, and they are divided into different areas.
