Dominic Kingsley was adopted by Ambrose and Adeline Kingsley, as a favor to a now-dead Serpent. Though, he has been with the family for so long, that he's never questioned his place in the family, as Leo's twin brother. Along with Leonidas Kingsley, Dominic Kinglsey is and elder son of Ambrose and Adeline Kingsley. Much unlike his twin brother, Leo, Dominic was always a troublemaker for the family. We was out of the womb causing trouble for everyone. He loved his mother very much, but his father had always been a bit too distant and focused on work for him. He had followed his twin brother in the crowd of wrong-doing, where Leo was stealing and breaking things, Dom was doing some different things. While he did steal and such, he was also coerced into helping some of his friends out by, for a lack of better terms, muling drugs from one group to another. He was eight at the time. Eight. Imagine what happened when he was caught. Thankfully, he never really was. While his brother closed himself off from the family, Dom would always try to assure Leo that he always had a friend with him.
When Leo and Dom were nine, their first signs of magic showed. It was a bit earlier than Leo's, and his was also slightly more mundane - But it freaked his friends right out! When one of his boys were getting beat on by some of the older boys, Dom went to defend him, and before anyone could touch either of them again, three of the older boys were blown on their behinds by an unknown froce - In fact, it affected everyone except Dom, as if it had released from him. When he turned eleven, the twins started at Ilvermorny.
Beginning in his second year is when things started to go down for Dom. His muling turned into selling, selling turned into using. By the beginning of his fourth year, he was beginning his addiction to Codeine.While Dom had a multitude of friends, he felt more alone than ever.... And he hid it with drugs. Lots of it. Then his mother died, which really only amplified his need. Dom had been disassociated at the time of his father's announcement of them moving to England. The move was a little of a shock for him.
Dom knew about Leo's escapade with his aunt, and really, Dom had no choice but to support his twin brother. The two are aiming to get in contact with their aunt, no matter what. Meanwhile, Dom's found his place in England, alongside his close friend and Slytherin Legend, Isabella Gaunt. The two are pretty close, and he's usually the only one who can call her Bella, even getting annoyed and protective when others call her by that nickname. The two have been through some stuff, including having been arrested together for being complicit in black market sales. That didn't teach them a lesson, as they had continued their little escapades, even running a small black market of their own.
