Cirilla Fiona Elen Riannon (known as Ciri or the Lion Cub of Cintra), was born in 1253 or 1252, and most likely during the Belleteyn holiday. She is a Princess of Cintra, and the daughter of Pavetta and Duny. She is the granddaughter of Queen Calanthe.
After Geralt of Rivia lifted a curse from Duny, the Urcheon of Erlenwald, he demanded from Duny his wife Pavetta's firstborn child, a child he had but didn't know he had, due to the Law of Surprise. Six years to the day after the child's birth, Geralt went back to Cintra for her, but did not take her with him to Kaer Morhen at that time. In fact, he didn't even lay eyes on her and only spoke with Calanthe. The Queen divulged no information to him, not even the child's gender. This child was named Cirilla.
While she was still an infant, Ciri's parents were both lost in a storm at sea. They were presumed dead. She spent her youth in Cintra and the Skellige Islands in the care of her grandmother and her uncle.
