Ten years ago, the world ended. Not through war... but through a Merge. When a meteor struck the hidden dungeon beneath Earth, reality shattered. Arcane energy flooded the planet, and the horrors sealed within were unleashed upon humanity. Now, monsters born from fear roam the ruins of civilization-and the sight of them alone can break a normal human's mind. Only those born on the day of the Merge possess Arcane Prowess-rare individuals who wield power beyond human limits. Mar is one of them. He's not the strongest. Not the smartest. But when danger strikes, Mar moves before fear can stop him-saving lives with instincts even he doesn't understand. Alongside Mila, a healer who refuses to let anyone die, and a growing group of powerful allies, Mar steps into a world ruled by monsters... and monsters disguised as men. But as the truth of Arcane energy unfolds and humanity begins to fracture, one name rises above all others in fear and strength: Kahn. In a world where survival belongs only to the powerful, Mar will learn that instinct alone isn't enough. Because some battles don't just test your strength... They decide what kind of monster you become.
