Kaen Stark. He was one of the leaders in the former Brave Swift Sword mercenary group, and his nickname was "White Eagle Knight".
Unlike the other grassroots mercenaries that sometimes didn't even have family names, Stark was the family name of a quite renowned local noble. However, in Kaen's grandfather's generation, the Starks had already become impoverished nobles. Kaen's money for studying and learning how to fight had all been borrowed from distant relatives.
His emblem of a white eagle was a noble emblem that had lost all meaning already. It was also the greatest symbol of irony for any useless son of an accomplished noble.
Kaen had grown up while listening to stories about his ancestors' heroism. Yet, all he grew up to receive was the reality that his family had fallen upon hard times. Apart from the martial arts passed down through his family and his family armor, he basically had nothing else at all.
