In the middle of the world sits a tower in the middle of the continent in the human realm.
Portals appear at random around the planet and when they do they are assigned ranks from least dangerous to most dangerous.
These portals are portals to other lands outside of our dimension, these lands are the home of monsters and sometimes other civilizations.
When these portals aren't cleared monsters will pour out.
These portals appear everywhere except for the lands of the fae for unknown reasons.
The tower operates the same way as these portals, its an unknown area thats unknown whether it has an end to its structure or not.
Each level of the tower is its own world full of monsters and civilizations fighting these monsters.
Both the tower and the portals are connected to the dimensional rift, though the relation is mostly unknown.
All thats known is that they emit the same mysterious energy.
Portals are known as dungeons in this world.
The ranks the portals are assigned have 7 levels.
Level 1 is the weakest and where you can find simple monsters that are still dangerous but not as dangerous.
Small monsters like slimes or powerful boars.
Level 2 is a bit more complex, this is where you find monsters that work in groups, so the small monsters level 1 are now more intelligent and even have their own weapons but still weak.
Level 3 is where monsters start to have their own mounts and have even developed higher forms of intelligence to be able to craft and farm.
These 3 levels are known as the beginning areas.
Level 4 though is where the danger spikes.
Monsters will start to become much bigger, bigger than humans by a large margin while also having the intelligence of a level 3 monster but also having magic at their disposal too.
Level 5 is where monsters have developed their own martial arts specific to their species and even a language and combat strategies.
Level 6 is known as the doom level as its where most people end up dying after climbing the ranks.
Level 6 is where the land becomes extremely harsh with only the monsters able to survive, the monsters would use their land too their advantage in order to kill invaders.
Level 7 isn't necessarily a level but more of a classification for dungeons of extreme danger that far outweighs level 6.
So level 7s vary among each other in terms of danger but they are all extremely dangerous.
This realm is where the land itself is sentient, its wants to kill invaders and can even plan, strategize and use magic to do it.
The only way to stop a living dungeon is to find the core which is extremely hard as the land will do everything in its power to stop anyone from finding it.
There are no monsters in level 7s, only the land itself.
It was the summer of the magical year 2XXX, the continent of Helis Villania was buzzing with the sounds of locust and metal.
its capitol Cidalia, was quite an envious sight for those that lived anywhere else.
More advanced, urban, with knowledge easily excessible at your fingertips.
And in the middle of that famous capitol sat the magical university military academy floria, the number one academy in the entire world.
