Orion was born in Essex, England but later moved to Wales. At two years of age Orion found out that he was a wizard. He later became a student at Hogwarts where he was sorted into Slytherin. At Hogwarts he would participate in nearly every class. He always wanted to be a Ministry employee and so studied hard and got good grade's. He had many friend and enemies and hates Muggles and Muggle Born.
At 18 Orion left Hogwarts with some N.E.W.Ts and O.W.Ls under his belt and a whole load of enthusiasm. After some time working at Gringotts as a guard he got a full time job at the Daily Prophet. Here he met his soon to be wife Elizabeth. After some time of dating they married.
Some years later when Orion was 28 his wife bore him a son. They named him Gruffudd. On Gruffudd's first birthday Orion landed a job in the Ministry. He still has this job and is very happy as head of his department.
Orion is an aggressive character but he knows his place and would never speak out of place. On the other hand he would do anything to help his family, distant and close. He may have a short hand on some people but it's because he runs a strict line of business.
