Endless Dungeon: The Misadventures of Arthur Gray [Litrpg/Dungeon]

Arthur Gray is a man defined by absence. As a shut-in otaku with no professional prospects and a family that views his existence as a burden, he has spent his youth drifting through the periphery of society.  Through his life, Arthur was a nobody and a ghost in the machine of a reality he never learned how to live. This cycle of mediocrity is shattered when Arthur is suddenly pulled from his mundane existence and thrust into the Endless Dungeon of Eteria.  This is no mere labyrinth, but an entire world built upon the verticality of its challenges. It is a realm where the earth itself rises in infinite tiers toward an unreachable sky.  For Arthur, this is not a crisis, but a long-awaited second chance. Granted a clean slate, he rejects the traditional swords and sorcery of this new world.  Instead, he selects the Gunner class, a specialized path requiring precision, cold nerves, and a strategic mind he never knew he possessed. However, the climb is too treacherous to face alone. Along the way, Arthur finds himself at the center of a makeshift party of outcasts.  These are a collection of warriors and misfits who are just as broken and dysfunctional as he is. What starts as a pact of convenience evolves into a chaotic and fiercely loyal found family.  Together, they must navigate biome-sized floors, survive eldritch horrors, and outmaneuver rival factions who seek to gatekeep the ultimate secrets of the world. From the lowest depths of social isolation to the heights of Eterian legend, Arthur’s journey is no longer about surviving. It is about proving that even a nobody can rewrite the laws of a world if they have the will to pull the trigger.
