[OP: ]
In every special structure of the Worldline, there were times when the dungeon is locked after a participant enters it. The dimensional dungeons are the main kind of dungeon that show this kind of behaviour.
Some tasks are given to the participants of the dungeon and only after completing at least all of the given tasks can they get out of the place if they don't have an Escape crystal that was worth around 10,000 Oz.
This dungeon was also the same and had tasks. Something that the 'players' in their game would have called 'quests' of the dungeon.
However, the quests do not exist for them who could not be categorised as players but instead a part of this world.
Thus, these dungeon tasks were only dungeon tasks for them. Something they would complete naturally since they were here.
