The huge desolate ruins were situated out of the wasteland not too far from the forest and the elf folk's village. In the past timeline, it was the main topic on what is the main purpose of the ruins. Since the place is just full of puzzles and a labyrinth maze but no monsters to kill made the community theorizes the main purpose of the place.
When it was conquered and found out the bottom of the labyrinth is just an empty room without anything even a single common chest that contains the most common items made the players who were invested in solving the puzzle got angry and said that the time and effort they did for cracking all of the puzzles are just a big waste of time. It was kind of pitiful since their efforts were not even rewarded.
