In the deepest part of the Dragon Empire, the eternal prison, no one other than authorized people were allowed to enter, yet, in the most secluded area of Area 1, the place where the worst of the worst criminals were kept, there was a cave.
This cave was called the cave of eternal suffering. The longer one stayed in this cave, the harder it would get for them to breathe, but the moment they were about to lose their life due to suffocation, they would be able to breathe again, only to have the same process repeat.
For that, however, there was a condition: The victim, or the one who is supposed to be tortured that way, should be bound by the chains hanging down from the ceiling.
If all of the spots are filled, then you can just kill one of them or push them into the pond at the center of the cave.
