Alaric Thorn was just a blacksmith in the 12th century—a husband, a father, a simple man. Until the day everything was taken from him. His wife murdered. His daughters stolen. And he himself slaughtered, powerless to protect the people he loved. But death did not end his story. Dragged into a supernatural realm after dying, Alaric made a desperate bargain: power in exchange for completing a mission in the future. A mission he did not understand. He returned to Earth centuries later—only to realize his revenge no longer existed. Four hundred years had passed. His family long gone. Their killer long dead. And Alaric… could no longer die. Cursed with immortality, he wandered through ages and empires, trying every possible way to end his life—failing each time. All he wanted was to go back in time and fix what he had lost. But when he finally stepped into a time machine, fate betrayed him again. Instead of the past… Alaric was thrown into another realm entirely—a brutal world crawling with monsters, ancient races, and system-like powers. Here, strength must be earned through blood, each battle pushing him closer to awakening his true potential. In this realm, he is no longer just a wanderer. He is a rising lord. A conqueror. A man destined to build an empire strong enough to challenge a king— a king who bears the same name as the monster who destroyed his life on Earth. As Alaric fights beasts, defeats tyrants, and gathers allies and armies, he discovers the truth behind the mission he accepted centuries ago: To reclaim his fate… To break his immortal curse… To rewrite the destiny stolen from him… He must rise as the Immortal King. The true master of the Dark Realm he was fated to rule.
