In the middle of the night, there were purple and red full moons in the sky. The world was veiled in a mysterious color under the moonlight. It was late, and the crowded White Capital was now quiet. Although the lights were shining brightly, there was nobody on the street. However, not everybody was sleeping at such an hour. Some people were still working hard. Not many people in the White Capital knew that there was an underworld hiding hundreds of meters under the massive city.
Outside an underground building in the White Capital were holy fire-level guards and patrol squads issuing a stern warning that no outsiders were allowed in. The building was like a giant metal beast that was tempered from a special metal into the design of a creature. It seemed like the perfect existence in the underworld which did not seem absurd at all as it gave one the feeling that it had existed since tens of thousands of years ago.
