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.

For a thousand years, the Night Empire has prospered under the rule of the feared Vampire King, Lucien Draven. To preserve the balance between life and death, every new king must perform the Crimson Vow during the Blood Eclipse, a sacred ritual meant to bind him to his destined Vampire Queen. But this time, the ritual goes terribly wrong. Instead of summoning a vampire bride, Lucien accidentally binds himself to Death herself, the immortal guardian who has guided every soul into the afterlife since the beginning of creation. Their impossible marriage shatters the natural order. Souls stop crossing into the afterlife. The dead refuse to stay buried. Ancient monsters imprisoned beyond the Veil begin to awaken, sensing that Death can no longer fulfill her duty. As vampire nobles plot to overthrow their mysterious new queen and kingdoms descend into chaos, Lucien discovers the woman beneath the legend. Death is not cold or cruel. She is lonely, compassionate, and exhausted by an eternity of watching every love story end. For the first time in existence, Death is forced to choose between duty and desire. If she remains Queen, the world may perish. If she leaves, she must take the soul of the man she has fallen in love with.

He died killing the Demon King. He woke up sixty years too early. Now the monster is a young man. And he is running out of reasons to stay away. --- Lysan Dusk was the hero who saved humanity. He killed the Demon King, ended the war, and delivered the world from suffering, and his reward was betrayal. He wakes up in a young student's body in a dormitory room of a magical academy, and the calender shows that the date sixty years before he was born. The world outside hasn't broken yet. The war hasn't happened. Lysan's plan is to keep it that way by staying completely out of it. Fail his combat exams, spend whatever borrowed time he has left, living a quiet life, where nothing requires him to be a hero. The man who will become the Demon King, the most feared monster in history is still young and beautiful, with pale grey eyes that find Lysan across every crowded room like he is the only person worth seeing. Lysan knows what those eyes will become. He has looked into them across battlefields, spent a lifetime seeing them in nightmares. He never expected it to feel like this up close. Roman is everything Lysan was warned about — magnetic, dangerous, impossible to ignore. Everyone except Lysan, refuses to be charmed, refuses to feel anything at all. But now, he is failing spectacularly at them because Roman keeps finding him. Keeps watching him and making Lysan's carefully rebuilt walls feel like paper. Lysan knows the ending. But for the first time in two lifetimes, he is wondering if the ending can change. If the monster can be loved instead of killed. If staying is braver than running.
