Sancia of Sodden was Gutram's daughter from a second marriage, a princess of Sodden and the half-sister of Ekkehard of Sodden. She married Medell of Temeria, and thus became the mother of Foltest and Adda and the grandmother of Adda the White.
She never accepted the incestuous relationship between her children; it would've been reason enough to curse their child to become a striga.
The queen, King Medell's wife and mother of their common children, Foltest and Adda, is mentioned in the short story The Witcher, in The Last Wish-collection. In all books (novels and short stories), neither her name nor her origins are ever mentioned.
In the Netflix series
Queen Sancia, portrayed by Russian actress Katia Bokor, also appears briefly in The Witcher TV-Series in Season 1/Episode 3: Betrayer Moon. Next to her, viewers can see young Foltest and his sister, Adda.
