Dominic was born in Alice Springs to Joseph, a Curse-Breaker, and Melissa, a Computer Tech guru. He spent most of his childhood with his mother, as his father would always travel for work. This made him a bit of a mama's boy, but it also gave him time to learn the ins and outs of technology. By the age of 7, he was already taking apart electronics in the house and (mostly) putting them back together, much to his father's chagrin. Melissa encouraged it, of course, as the only way Dom would learn would be to tinker with everything.
One day, Joseph decided to show Dom the type of work that kept him away from home so often. Joseph had obtained a small locket that would melt the flesh of anyone who wore it. As he was deciphering the best way to break the curse, Dom felt sick. He stumbled and fell as visions flashed in his head. He couldn't decipher them. They were blurred flashes, disjointed. He screamed and passed out.
When he woke up, Dom frantically looked around, finding his father asleep at the side of his bed. He woke him up, telling him that his plan for the locket wouldn't work and would backfire. Joseph, a very accomplished Curse-Breaker, didn't believe him at first, but Melissa came in and said that he was probably right. She had been on the phone with Joseph's mother, Susan, who believed that Dom had the family curse, despite it only happening in females. Apparently, Susan had a similar reaction during her first vision, so it was possible Dom had them, too. Dominic was confused, but they explained that the family's bloodline would give rise to Seers every other generation. Over time, he would be able to control the ability, but would lose his eyesight more and more until he was blind. Joseph assured him it would be years before he ever had to worry about that, as his mother didn't go blind until her 50s.
Going to Tallygarunga, Dom took the opportunity to look into potential preventative measures to losing his sight. Surely some magical being had figured out a way around this issue. His results weren't too promising, so he instead decided to start looking at technology. The problem, of course, is getting tech to work properly in school and other magical places. Still, he spends most of his free time tinkering with some piece or another. As for school life itself, his past two years there have been rather uneventful. He struggled with Transfiguration, but excelled in Potions and Defense Against the Dark Arts. He also took an interest in Herbology in hopes of finding some herb that could help his impending malady, but to no avail, yet. As his third year loomed, he decided Divination could possibly help him learn more about his ability, so he signed up for that.
