He is described as having an uncompromising nature, pursuing his goals with relentless determination, and showing no mercy even to his own family. He is the one Alec is rebelling against in order to reclaim his rightful status and position. The emperor had marked Alec for removal, and Louvero's cruel nature makes the situation even more dangerous for those connected to Alec.
