Yennefer of Vengerberg was born on Belleteyn in the year 1173. She is a sorceress, and once resided in the capital city of Aedirn. She is the youngest-ever member of the Council of Sorcerers, and was later a target recruit for the Lodge of Sorceresses. She was and is romantically involved with Geralt of Rivia, and has served as a mother figure to his ward, Ciri. The lady of Vengerberg is famous for her beauty, beauty which has remained despite her stated age of 94 years (as of the events of The Tower of the Swallow.) She is well known for wearing black and white clothing, and using lilac and gooseberry perfumes. She has remarkable violet eyes and raven black hair, and is a quadroon of Elven ancestry (meaning her blood is ¼ elven).
