Twenty years ago, Leon Ashbourne was one of the top-ranked hunters, gifted with shadow-based powers and destined for greatness. During a raid on a mysterious high-level dungeon, he encountered a powerful Shadow Spirit that challenged his control over darkness. A fierce battle erupted, and though Leon defeated the entity, it dragged him into the Shadow Realm in a last act of defiance trapping him in eternal darkness.
Time passed differently inside. While only days passed in the real world, Leon endured two decades of agony, solitude, and endless battles against shadow beasts. But through this suffering, he mastered every inch of the realm, absorbing forbidden knowledge and evolving beyond the limits of any hunter.
Now, the seal is broken. Leon returns to a world that has forgotten him, where new powers have risen and his enemies walk free. Haunted by betrayal and fueled by vengeance, he vows to reclaim what was stolen starting with the ones who left him to rot in the shadows.
