Timeless City
In the treacherous southeast quadrant of the Star Ocean, there is a No-Return Zone called the Riddle Archipelago, one of the three most dangerous no-return zones in the Star Ocean.
This Riddle Archipelago was proclaimed as such for two reasons. The first one was that in this place, any magic equipment starts to decay, and this strange decay also affects the beings with magic. Their magic power slowly dissipates before their magic orbits rot, and they eventually meet the fate of death.
The second reason no one wanted to tread anywhere near this place was that if someone were to enter this no-return zone unknowingly, they would find that no matter how much they came closer to one of these islands, they would never be able to reach it.
Not only that, but they will also not be able to return, and they will fall into this strange conundrum until they run out of resources and die helplessly.
