Not much is known about Pierce, other than he is a Knight of Asch. Pierce, is very loyal to his kingdom and used to serve under Rhal. It is shown in flashbacks that Pierce has slaughtered and endangered others by his superiors' commands. He likely did not enjoy murdering any of his victims as they were slaughtered under his superior's orders. When Pierce does decide to speak, he is usually very serious and asks many questions and when asked answers with short and straight forward answers.
