They shove you into a capsule for an experimental operation to treat a deadly illness. And you wake up in the body of a prince who was attempted to be killed together with his entire family. Everything left as a legacy of his mind is muscle memory and language. Power is already in the hands of your “uncle,” who became regent while the surviving seven-year-old brother lives. And you, to preserve your life, are sent to study at the University of Heoniz, supposedly for your own protection.
It seems simple: wait for the right moment, figure things out, and then return to court, taking the helm of the empire. Or find allies to overthrow the regent, taking his place. But the reality around you turns out to be far more complicated.
