In 212 AC, at the age of three, Cerelle became the ruling Lady of Casterly Rock. Her uncle, Gerold Lannister, served as her regent. Cerelle's rule would last for less than a year, as she herself would die in 213 AC. As her death had occurred at such a young age, it was whispered that her death, and the death of her father had been caused by Gerold, who, after Cerelle's death, became the ruling Lord of Casterly Rock.
