The Unending Dungeon

The Unending Dungeon or Infinite Labyrinth is the a location of the Ore dake Irerukakushi Dungeon.

It's a Hidden Dungeon where Noir learned how to exist and invade with his Great Sage skills. The remarks of the four layers of Ghosts suggest that 200-300 years ago. It is Olivia, not Noir, who first went inside after it was sealed.

It is located inside a cave located 15,000 meters southwest of the Royal Capital, in the mountains.

In addition to locating the entrance, you need to push the rotating wall on the left to reveal the stairs to a massive iron gate. No matter what kind of magic attack one summoned, it didn't seem like it'd budge in the least. It is also necessary to recite the required spell: "「The Hidden Dungeon only I can enter. Secretly becoming world strongest!」".

The Floors of the Dugeon are full of rare monsters and creatures, as Noir noticed after he saw its slimes, because the golden ones were pratically unheard of.

The Floors of the Unending Dungeon can simulate different environments, as the 7. Floor has a fake sun, and the 9. and 11. Floors were similar to a ocean and a volcano.

The Unening Dungeon can be very dangerous, because even its "bonus level", the Gold Forest, is full of dangerous creratures. As Noir progressed through the Floors, he noticed the monsters were getting stronger.

Besides monsters and creatures, the Dungeon is full of illusions and traps, as the Death Chains that sealed Olivia, and supposed humans like Huck, Uuck and Auck in the 8. Floor, the audience in the theater inside the Path of Laugther and Son and his battalion in the Path of Anger.
