It could have been written in the stars, or perhaps a simple cosmic fluke, but the muggle family of the Sharpes would be blessed not just with one, but two kids with magical affinity. The first was Diana, and 11 years later, her younger brother Gideon would follow. Conceived when they planned to sending Diana to Tallygarunga, Gideon was born in a house where he was practically the only child, only knowing about the existence of his sister through letters that she sent to their family. They could have thought they could pretend their family was normal with a new start, but what they didn't realize, is that Gideon possessed the same magical attribute his sister had. Of course, such episodes were very far and few in-between, and his mind was not developed enough to understand what happened around him, so his early years were actually rather normal.
However, things would change when Diana finally arrived to their home, when Gideon was barely 6 years old. By then, he already gained a better awareness of his self, even managing to show Diana a display of the magic he could make, a choice that would change his life forever. Diana would then start sh<owing him more about the wonders of magic she learned in Tallygarunda, about the world of wizardry that existed right under their noses, and even giving him some material to hone his magic. And while this marveled his very young mind, there was trade-off for such knowledge: Secrecy, and making his sister's life a worse hell than it already was.
He didn't understand just how anti-magic their parents were, and he underestimated how staunch they were in their beliefs. At first, he didn't see just how bad they treated her whenever she blame herself for his own magic, but when he discovered, he tried to stop Diana from doing so, to the point he even tried stopping himself from doing any more magic, at least in their parents' presence. Which was a lot of the time, considering how he was still a very young kid. But something else Gideon underestimated was his sister's ideal to see his potential unraveled.
In a rather underhanded manner, and most likely as a way to get back on her parents, Diana managed to become his legal guardian once she was an adult, and performed a powerful spell to change the memories of everyone around them, essentially erasing the two of them ever existed. Before he was even 9 years old, he was already quite practically unpersoned by his own sister, a fact he only learned after the fact, as the two were on the run. A whirlwind of emotions coursed through his childish mind when he heard the news; anger, sadness, confusion, fear. The true weight of her actions couldn't land on his mind due to just how incredible his scenario was, and while a lot of kids would feel like they were going on a grand adventure away from home, Gideon was not someone like that.
Mixed feelings was an understatement, but Diana tried to reassure him to trust her, something which he eventually came to do. What other choice did he have? Tallygarunga was the next, and only destination the two fugitives could take, and while Diana focused on finishing her studies, and eventually becoming the breadwinner of the pair, Gideon began his studies in Whitlam Bilby, setting him on the course proper to his age. Over the years, the feeling of that fateful afternoon began to move into the back of his mind, as he adjusted into his new life little by little, with each year he managed to pass successfully.
But, that didn't mean that they were gone, as while he felt the kind of love and respect one could have for an older sibling that tries their best to provide for him, sometimes he couldn't help but feel uncertainty about the future he could have, all thanks to the past that taken away from him. It would be a lie to say that sometimes he didn't feel a distant, but puncturing sense of resentment over his situation, and even towards his sister, but even on this fourth year of a regular student, he still can't make heads or tails over how he should feel. He could only hope the remaining years he has will help him understand himself.
