The World after the Fall

Jaehwan, a Swordsman, has spent 30 years mastering the "Tower of Nightmare," reaching maximum level and maxing out all his stats. Yet, he finds himself questioning the very nature of his reality. He develops a mysterious new power, 'Suspicion,' allowing him to glimpse the truth behind the world's structure.

Refusing to progress beyond the tutorial's 99th floor, Jaehwan enters into a tense negotiation with Beastlain, a powerful demon overseeing the tower. It is revealed that the universe consists of "" and countless "", with Earth being just one of the latter. The "Tower of Nightmare" serves as a brutal training ground, preparing "Walkers" like Jaehwan to adapt to the complex "Interface System" of the greater universe. As the demon grows frustrated, Jaehwan aims to uncover the hidden motives behind the system and break free from its predetermined path.
