MTL - Stormwind God - Chapter 54 Magic circuit (below)

At nineteen, Dexter was already one of the world’s most celebrated authors. His books topped charts. Critics praised his genius. Fans devoured every word. But behind the acclaim was a lonely boy—raised without parents, love, or real friends—just stories.He published his first novel at fourteen. By seventeen, he was a literary star. But the higher he rose, the hollower it felt.Then came the writer’s block. The headaches. The blackout. And the transmigration.Dexter awoke in the body of Daylan, a disgraced young man in a crumbling, medieval world laced with steampunk tech, divine law, and political unrest. Daylan had already failed two of the three sacred Trials—rites that determine one’s magical potential. He was drowning in debt, entangled in plots to overthrow a corrupt Divine Church, and branded a lost cause.With no way back, Dexter took the final Trial—the most brutal of them all—and began a path that would earn him the whispered title: Soldier, Poet, King.But as his powers grew, one question haunted him: Did he truly die? And if so, who—or what—chose to bring him back?

How long will it take for a murdered thief to distill into something monstrous? In this story the darkness only grows stronger, and its reach only grows wider as it expands by devouring the life that surrounds it. This is a dark fantasy where evil is a where, not just a who that focuses on slow progression, undeath, and atmospheric storytelling.
