- Description from novelbuddy

In a world that blends the magic of the steam age with the grandeur of the medieval era, a man wakes up suddenly in a body he does not recognize, in a strange reality that does not belong to him, bearing a name that is not his and a mind stripped of all memories. His name is Jevan or so they say.In the city of Medlia, specifically in the lower district, where poverty and misery reign, the people are not ruled by laws but by fear of the gangs.Jevan discovers the existence of extraordinary powers known as Authorities abilities that defy all logic, wielded by some for domination and by others as a means of survival. Before long, he finds himself cornered on all sides:Bloodthirsty gangs, mysterious agents, secret organizations. He becomes entangled in countless troubles from a past that is not his own. In a city torn apart by class struggles, devouring those without power, Jevan begins a journey to uncover himself or the truth of the body he never chose and has no luxury of escaping.

I died in my world… and woke up in someone else’s story.But not as the hero. Not as the villain. Not even as a side character who mattered. I’m… an NPC—a nobody, a background observer, invisible to everyone.At first, I thought I was powerless. But then I discovered something strange: I could leave notes, whisper hints, move objects… small nudges that subtly changed the story. Every tiny action rippled through the plot, shaping outcomes, saving lives, and altering the fate of heroines, heroes, and even villains.The catch? The story is alive. It resists interference. Push too hard, and accidents happen. Plot twists turn against me. Minor disasters loom. The more I try to influence, the more the story fights back.So I play carefully. I study. I manipulate quietly. I watch the heroines, heroes, and overlooked side characters, weaving invisible threads that guide them. I don’t fight. I don’t cheat. I survive—and maybe, just maybe, I can change the story from the shadows.From an unnoticed NPC to the hidden hand behind the world, I’ll prove that even a nobody can rewrite the story.
