Prison of Seven Realms - The Hero Crowned as a Demon Lord

Twenty years of service. Zero benefits. One ultimate betrayal. Sergei Starburner was the perfect puppet. As the 13th "Dawn Warrior," he bled for the Papal States and butchered "monsters" in the name of the God of Light, Sol. But when he finally reached the Throne of Chaos, he didn't find a monster. He found a mirror—and a "System" that had been suppressing his true self for two decades. In his past life on Earth, Sergei wasn't a knight. He was a Special Forces veteran and a top-tier Software CEO. Now, the "Hero" is dead. The "CEO of Chaos" has checked in. Looking at the world of Aethergard, Sergei doesn't see a magical wonderland; he sees a bankrupt company riddled with legacy code, predatory "Faith Taxes," and a "God" who acts like a corrupt board chairman. With a "Human Power Bank" girl by his side and four "loyal traitors" as his executives, Sergei is embarking on the ultimate hostile takeover. Magic? It’s just distributed algorithms. Divine Punishment? That’s just remote formatting. The Hero Squad? They’re just competitors who need to be liquidated. The Seven Realms are a prison. It's time for some disruptive innovation.
