Sinnie was born in Altoona, Pennsylvania to the Circle of Moonlight coven. He stayed with his coven and family, going to the Pleasant Valley Elementary school until he was 12. He then attented Altoona Area High School until he was 16. Once 16, as his coven requires, he was sent off to a private witch academy, called Académie de magie Saint-Bernard, to hone his skills as a witch. After graduating, nearly at the top of his class, he returned home to his coven in Altoona, PA. He stayed home for nearly a year before his Magna told him he needed to do something with himself and so he found a job at the local magical Super⚝Market.

At the Super⚝Market Sinnie started as a simple cashier, often getting stuck on registers 4 and 9. After about a year of running the registers he was moved to customer service. Customer service proved to be the end of his more cheerful personality. After two years of working at customer service Sinnie was moved to the Magic department where he's stayed to the present day.

Sinnie has a rather "no care" attitude when it comes to work, however, when he's at home or away from the store he can be rather pleasant. He's an independent kind of person and doesn't like to ask for help unless he knows he really needs it. While his personality can be a bit of a hassle sometimes he's still a kind person and will go out of his way for his friends and family if knows he can help them with something they need.
