She was raised in a traditional pureblood household where discipline, manners, and poise were expected from an early age. She is the youngest of three children with two older brothers. She is often considered the favourite child because she is obedient, well-mannered, and rarely caused trouble. Her parents held her to high standards but were affectionate towards her. Her childhood friends are mostly children from selected other pureblood families. She grew up in a comfortable lavish family manor surrounded by books, magic and traditions. "magic in her blood"

Celeste's first accidental magic occurred when she was 8 years old. It happened in the Carroway family library when she was searching for a book on one of the higher shelves. As she was climbing down the ladder, she lost her balance and began to fall. Instead of hitting the wooden floor, she suddenly began to float and remained suspended high in the air for a few seconds before landing gently. She expressed this events to her parents who quickly made her realise she had performed wandless magic.
