Flume Travel, the main means of transportation that gave those who use it their namesake, had been a mysterious thing since the moment it was stumbled upon thousands of years ago.
Back in those days, it was a thing of wonder, mystery, and magic.
Terrans fought and killed each other not for territory or wealth but instead over who would control the mystical artifacts.
However, over time, that changed as more and more flume stones were offered up by the mysterious entity known as the Traveler's Display.
What was once viewed as a god-like artifact became a normal way of life for those who had Awakened.
And the fact that a certain Ash Blond Lad bobbed up and down on the currents of Energia, carrying him back to Terra, while completely unable to focus or immerse himself in what had originally been an amazing phenomenon to him, was proof that the wonder of the mystical artifact had already become a normal part of his life.
