Keira Metz of Carreras is a sorceress. She is a former advisor to King Foltest of Temeria, a role that has also been held by Triss Merigold and Fercart. She is fond of luxury, despises the dirtiness of the outdoors, and is rather eccentric in nature. She makes aphrodisiacs, and is considered to be a nymphomaniac by Sabrina Glevissig.
During the coup on Thanedd Island, she was thrown from a window by Artaud Terranova. She landed on Geralt of Rivia, who was passing below looking for his former ward, Ciri. Later, Keira became one of the youngest members of the newly formed Lodge of Sorceresses.
