Adrián Vélez, a renowned history professor, never imagined his vast knowledge would become his greatest weapon. When a heart attack ends his modern life, he awakens in the body of Aldric de Hautterre, the son of a nobleman in the brutal and treacherous Middle Ages.

In an era where power is taken, not given, can he carve his own destiny and reshape history itself?
