At the heart of this dark tapestry lies Narzan, a nation feared and despised, where cruelty is law and ambition a deadly game. The lands of mortals are but a fragile sanctuary, bordered by forbidden realms—the infernal Demon Realm, where nightmares are born; the accursed Lost Soul Realm, where the damned wander endlessly; and the enigmatic Elven Kingdom, shrouded in secrets and ancient power. These realms whisper of horrors and treasures that could reshape the very fabric of existence.Above it all looms the Weave of Magic, an ancient force that binds life, death, and destiny.

In this world where the strong devour the weak, hope is a fleeting illusion, and mercy is a tale for the foolish.Veythor is a man cursed by the fates, his existence a relentless cycle of suffering. Across three lives, he has endured betrayal, torment, and death. On Earth, he was a man broken by those he trusted—betrayed by family, ruined by love, and condemned to die in despair.
