Margrave’s Bastard Son was The Emperor

Story:

As a boy, I ascended to the throne as an emperor, only to be decapitated before reaching adulthood. My tragic fate stemmed from being the first noble magician. "I hope you are never born again, Ian." With the traitor's parting words, I believed it was the end, but… "You are the symbol of peace. What greater honor could there be for someone as lowly as yourself?" I became the bastard of a Margrave who perished a century ago. Destined to be sold as a pawn to the vulgar, insensible barbarians on our border.
