Earth is on the tail end of its recovery after suffering near-apocalyptic events. Catastrophic storms and sudden, dramatic shifts of the tectonic plates almost destroyed modern society. And to make matters worse, a mysterious disease that would later become known as the Deep Sleep Syndrome swept through the population. Penthus Argyris is one such person affected by this illness. Abandoned by his mother—his last living relative—he wastes away in a hospital ward.

It was lonely, but Pent had grown used to it. He no longer dreamed of traveling across the earth to explore the ruins of the fallen nations; the world outside his sterile white cage was all but a distant fantasy.

Pent had all but come to terms with his lot in life—that is until his adopted cousin showed up out of the blue with some surprising news… News that would shake the tentative foundation that Humanity had only just managed to piece together.
