I had always been curious about what a prison built by the Xyrin Empire would look like. Such a powerful, ultimate civilization would surely not detain ordinary characters. Those prisoners could potentially be dangerous beings that even a Xyrin Apostle could not defeat alone. One can imagine the difficulty of keeping such unstable elements securely in their cells. Therefore, in my imagination, this prison, described by Sandora as the most impregnable apart from the Divine Prison, must have been filled with a horrifying number of elite-level Xyrin Sentinels, equipped with devastatingly powerful guard gun mounts, and had incredibly thick armor inside. In the midst of it all were the most dangerous criminals in the universe...
In a word, the prison should have been outrageous from the inside out, from top to bottom.
But I was wrong...
After entering this mysterious cage through a teleportation gate set in the outer walls of the prison, all I saw was a vast expanse of white fog.
