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.

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.

Renowned as war heroes who sacrificed themselves to rescue their daughter from kidnappers, Lena's parents were largely absent throughout her childhood, leaving her with complicated feelings about their legacy and her own identity. As Lena struggles to understand her newfound identity and the abilities that begin to manifest, she uncovers a web of secrets about her parents' true role in the war. They weren't just fighting for humanity; they were part of a hidden movement working toward peace between humans and subnaturals. More importantly, Lena learns she was kidnapped not by chance. Hunted by extremists from both sides who either want to use her power or eliminate her entirely, Lena must navigate a dangerous landscape of political intrigue and ancient supernatural factions. Along the way, she assembles an unlikely group of allies—humans sympathetic to the sub cause, subs living in hiding among humans, and others like her caught between worlds. As her powers grow and her understanding of both sides deepens, Lena realizes that ending the war might require more than diplomacy or combat—it might demand a fundamental reimagining of what it means to be human or supernatural in a world where the boundaries between the two are increasingly blurred. But to fulfill her destiny, Lena must first confront the truth about her kidnapping, her parents' sacrifice, —a truth that will test her loyalty to both sides of her heritage and force her to decide what kind of world she wants to fight for.
