“His novel. His rules. His fight to take it all back.”Who would have thought Tavian would end up trapped inside his own novel?Not the chosen one. Not the villain.Just a forgettable extra with laughable stats and no place in the story he once ruled.And the protagonist he shaped into a perfect weapon?He’s real—and hunting him.Armed only with the knowledge of the world he created, Tavian has one choice: exploit the system he built… or be devoured by his own creation.He knows how the story is supposed to end.And he won’t let anyone else decide his fate—especially not the characters he once controlled.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?
