This world had undergone astonishing historical changes. With the Great Annihilation as the dividing point, even the fundamental laws of the entire world had been turned upside down. The Deep Sea Era after the Great Annihilation and the Order Era before it could almost be regarded as two entirely different "worlds."
Even so, there were still people tirelessly compiling historical materials passed down since the Great Annihilation, trying to piece together the true shape of history from the fragmented and even contradictory archives of various city-states.
Unfortunately, perhaps because the inheritance had been severed too thoroughly, or perhaps because the contradictions among the records of the various city-states were simply too chaotic, no one had yet found any relatively complete and reliable historical records from before the Great Annihilation.
No one knew what the world of the Order Era had truly been like.
Fortunately, however, relatively clear historical records had survived from the time of the Ancient Kingdom of Crete onward—though city-states rose and fell across the Boundless Sea, splitting and merging, the continuation of civilization itself had never been broken. Memories of the ancient kingdom remained in books, carved into massive stones, or passed down generation after generation within old and secretive families and societies.

Scholars believed that more than half the credit for the Deep Sea Era's civilization enduring to this day under such extremely adverse conditions belonged to the miracle that illuminated the world:
Phenomenon 001, the sun.
This was the phenomenon currently known to humanity with the greatest range and power. In fact, because of its immense scale and how "natural" its existence seemed, many scholars debated whether the sun was truly a phenomenon or a natural occurrence. Yet the earliest recordkeepers after the fall of
