Within the dream of the dreamer, the one who was dreamed of awoke.

On Terra, everyone has a 58% chance to “Awaken” as a Traveler—a chosen few who can access mystical portals called Flumes, allowing them to travel to Genovia, a world filled with unimaginable power, chaos, and danger. But not everyone gets to be a hero.Born into a struggling family with nothing but ragged clothes and a bleak future, Aoni Thurston, a total nobody with a humiliating One-Star Potential and G- stats across the board, knows his only chance at survival hinges on unlocking his hidden ability, something which all Traveler’s are gifted “Attributes.”But Aoni’s Attribute, “Progression,” holds a secret—a power to bend the rules of his ruthless reality. Each small victory, every step forward, earns him mysterious Progress Points, enabling him to transform his weaknesses into strength. Surviving the unforgiving snows of his desolate Territory, he faces isolation, despair, and near-death, all while unraveling the potential of his Attribute.In a world where power is everything, can Aoni claw his way from obscurity to greatness, or will the system grind him into dust? His future is uncertain, but one thing is clear—everything in his world can change through his Attribute: Progression.
