In the past couple of years, Crystal Palace has gained more and more fame. Following Duke Ifrit's decision to exploit the crystal formation in the dungeon, humans successfully expelled the monsters on multiple floors of the dungeon with the aid of mercenaries and adventurers.
Once the area was deemed safe and sound for human settlement, a team of highly trained warriors was brought in to make the area accessible and build multiple camps.
As the dungeon is a connecting dungeon, many waves have occurred up to this day, but none of them was as intense as this one.
The floor is stained with the blood of humans and monsters of every kind, making the whole area look more like hell than a dungeon.
Human camps were all destroyed except one. Access to crystals for humans will have to be delayed after the wave.
Additionally, the humans will have to decide whether or not they wish this dungeon to remain in existence because of the infection.
