Klaus had spent his entire existence as a puppet, bound by the strings of fate. However, a miraculous turn of events granted him a fresh start. The remnants of his former constraints smoldered in the ashes of his past. Now, unshackled and determined, he resolved to forge his destiny according to his own desires. No one, not even a deity, would be spared if they dared obstruct his path. Klaus was ready to wield the sword of vengeance and carve his own fate in the annals of history.

A 21st-century tech manager, accidentally thrust into the body of Emperor Commodus—yes, the infamous villain played by Joaquin Phoenix—has one goal: not to die like him.Armed with his wits and a hyper-intelligent AI on a solar-powered laptop, he must navigate the treacherous politics of ancient Rome. Everyone, including his own sister, expects the arrogant, decadent tyrant. Instead, they find a calculating reformer. But as he tries to avert the fall of the empire, he discovers that being a “good” emperor might be even more dangerous than being the monster everyone is waiting for.
