Nacht is a quiet person, but when he speaks, his voice is all business, as he doesn't like the joking mannerisms of Alba and tends to be short with Glaive. Nacht's father, Sigurd, was a knight in service of the kingdom of Falgabard. During an attack, Sigurd ordered his friend Graham to look out for his son, and help him escape. The loss of his family, and what later was revealed to be his entire homeland, turned Nacht into the cold, distant boy he is today. Nacht has an inability to let go of the issues of losing his father, resulting in Alba insulting Nacht, saying he has a "daddy complex".
