Gairwyn, a native of Cimmeria, is a worthy warrior and mistress of the lands around the stargate. She is a friend to SG-1, and brought them to Kendra to rescue O'Neill and Teal'c from Thor's Hammer. When her husband and his brothers were killed in a Goa'uld attack, she sought SG-1's help, and aided them in finding the Hall of Thor's Might to defeat Heru'ur. She was the first of her people to see Thor in his true Asgard form.
