Ethan Walker’s life takes a sudden and terrifying turn when he’s pulled from Earth and thrown into an impossibly deep pit—an otherworldly prison, barely 3 meters wide but stretching upward for kilometers, with a distant point of light above. Chosen by a mysterious Goddess for a task yet to be revealed, Ethan must survive and grow stronger within the tight, claustrophobic confines of the shaft. As the days blend into years, Ethan pushes his body to its limits, training relentlessly to enhance his strength, endurance, and resilience. But he is not alone in his struggle; unseen watchers from Earth observe his every move, ready to judge his worth. Trapped in isolation, with only his determination and the promise of escape at the distant light above, Ethan must overcome both the physical challenges of the pit and the mental strain of endless imprisonment—or risk losing himself to the void.
