1899 The Great Crime of the Arctic Sharks 

Throughout the history of the Spiritual World, various tribes, races, and civilizations have grown and evolved, using auxiliary technologies to facilitate their progress and stay ahead of other groups.

This was the case with the Seraphim tribe, which had ended in the Ocean Cataclysm when the Sky Whales, Quilins, and Dragons fought before the world's first God was born into the world's strongest tribe.

Just before that chaotic time, when several tribes met their end in the struggle for supremacy, a devastating era had ended, bringing countless benefits to the survivors.

However, some of them, such as the Seraphim tribe, were very weakened after the devastation, while others, such as the Sky Whale tribe, hadn't lost much of their strength during that era.
