Jamie Senate

Jamie Senate is the youngest son of Gerald Casterly and an unnamed woman and was the heir to House Casterly to Winter's Landing and the Northern Vale. Conceived out of wedlock, Jamie was born a bastard and had no claim to his father's throne. He was raised equal to his siblings but did not have the luxury of motherhood. Due to Jamie's father's unexpected death, Melchior Morgenstern was named the King of the Wintervale and the lord of Winter's Landing because of his marriage to Jamie's oldest sister. Melchior earned a bad reputation during his kingship and sought to have Jamie take his place, fearing rebellion and what that would do to the kingdom. At the age of twelve Melchior had Jamie legitimized and named him his rightful heir to the throne. When Jamie turned fifteen, he was named the King of the Northern Vale and the lord of Winter's Landing, though, he gave up his Casterly heritage and his holding of Winter's Landing and built himself a castle at the center of the kingdom, King's Rock.
