Biruta Anna Marquette Icarti was a sorceress from Rissberg and one of the eighteen masters operating there. Articulate and having delusions of being a superior magician, she was loyal to his kin. During the confusion Sorel Degerlund was on her side. He even sent an official letter to the Chapter, which suggested gracious punishment for the young wizard. She was forced to leave Rissberg and devoted to the pedagogy of Aretuza.
