Biography: Castor (Thorne) Mornstern was Born on the thirteen of May of 2012 to Cordelia and Jasper Thorne. His roots are split between Irish and English due to the fact of his mother being born in ireland and his father in england. His family life growing up was semi normal, his dad being an auror and his mother working at the ministry of magic, it was easy to switch off the responsibility of taking care of him between them. Castor was a playful child, always wanting to go out and play with bugs or just running around the house, which made it harder for his parents to take care of him because they got more and more invested into their work.

Due to Cordelia and Jasper's jobs, they soon had targets painted on their backs, and due to the amount of enemies they had they would have to decide between keeping Castor and possibly putting him in harm's way, or releasing him into foster care so he could be safe? At the end of a long discussion, Castor's parents decided that they wouldn't be able to care for him properly or keep him safe, so they decided to give him up, when Castor was but a young boy. The age of 7 to be exact. Before giving him up though, his parents had told him that everything would be okay, and for him to always stay a good and strong boy. Being sent into foster care at the age of 7 made it so Castor somewhat knew what was going on, and between his 5 years in foster care he bounced around from numerous homes, one's who didn't want him. Or ones who did that couldn't care for him like he would've needed, until the age of 11 when he was adopted by the Mornstern's.

First Instance of Magic: When Castor was only eight years old, his first year in foster care, he was having a rough night and missing his parents. His emotions built up inside of him and exploded out, his small teddy bear sitting in his bed had began to glow and then it disappeared, only to reappear a few seconds later.
