Evony was born 4 years after the fall of Lord Voldemort. More importantly, she was born 4 years after one of the largest incidents in the ever-growing list of conflicts between centaurs and humans. This, of course, was the untimely demise of Delorus Umbridge at the hands of the centaurs of Hogwarts. This one event would be the breaking point for the Ministry of Magic, and they would demand that changes be made to prevent future issues of this nature. It would be years later before any plan would actually be put into effect. As it stood, there were many centaur herds spread across Europe, many of which had chosen to isolate themselves from the humans who now demanded they comply with treaties and legislation to control them.
While many of the herds refused to comply, bringing diplomatic relations to a standstill, a few herds would see the value in making some effort to amend the damages done, and try to bridge these gaps. The Wynter herd in France was one of these groups. Evony was chosen early in her youth for the opportunity of a magical exchange. She was to be sent off to a local magical school where she would study like a human. and bring her experiences back to her herd later. The idea was that if humans and Centaurs had a chance to become closer that the aggression that had become status quo might lessen or even stop altogether.
She would be groomed until the day she was old enough to attend Beauxbatons, to which she had been accepted to years prior as a condition of the exchange. Her first year was incredibly difficult, though most of this came from the social stigma she suffered from being a centaur. Strangely though, despite her heritage, she still strived to make friends as all children tend to do. This was difficult for young Evony though as she quite literally did not seem to fit into the regular wizarding world. This only caused her to push her studies that much further, allowing her to advance her skill with magic and keep up with the more gifted students of her generation.
As the years went on her own skills not only continued to improve, but her social skills began to develop. It seemed that as she focused less on trying to make friends, that suddenly these relationships began to present themselves. Of course, these were not the sort of relationships that one would consider healthy as many of the girls that befriended her did so out of the purity of her blood and the scores in her classes. Despite being of a different species Evony was, perhaps, purer blooded than anyone else there at the time, as her kind is unable to breed with others. To the elitists of Beauxbatons, that was enough to get noticed.
In her fifth year, Evony was given the opportunity to study abroad with another wizarding school. She was told that the experience would be good for her and that it would do well to broaden her horizons. After some deliberation, she decided to take the opportunity. Over the last few years, her bonds with her herd had been strained, and she had determined that it would be better if she continued on her journey to achieve a magical education without being held back by the already weakened relationships of her past. Part of the reason she agreed to the exchange was that she had already learned English a few years prior and had been told that the school she would be going to was English speaking.
