Hannibal Quasar commands as captain of the Knight Guards of Housman, a rank earned after his service as a veteran of the Valbanill War. The events of that conflict forged his combat philosophy, which holds that carrying fear into battle is essential for a warrior to achieve their full potential; he believes those without fear are more likely to choose the wrong path in life.

He retains the trust and respect of his subordinates, skillfully encouraging them while remaining openly realistic about the sacrifices demanded by war. Honoring fallen comrades is a matter of deep importance to him.

Although shaped by extensive and harsh experience, he is neither ill-humored nor embittered, but instead possesses a sense of joy and an occasional inclination toward humor. He is bald with brown eyes, and is typically depicted with facial hair and scars. His knightly rank is reflected in his attire, which consists of armor and a cape.
