just gonna quickly c+p it lol. coralie had a friend that she grew up next to in bamburgh. when they grew up together, they both found out they were magical and even got acceptance letters at the same time but while at school, everything changed. her friend became a slytherin and cora a gryffindor. when they were on the pitch or in classrooms, they were combative and stereotypically pitted against each other but while they were home in bamburgh, they were the loving lots together...until they're back at school once more. after they graduated, they moved in separate directions until they always come back to bamburgh for an occasion.
