Aquarius is the type of girl who likes to deviate herself from the crowd and create her own path, and is constantly seeking out new bouts of knowledge. Although she likes to deviate herself from the path others take, sometimes she'll attempt to take that route as well, but only if it benefits her. Aquarius would rather spend her time alone, but when she's thrown into social situations she turns into a social butterfly which some would find rather odd. Aquarius likes to experience thing from both sides, and formulates her own answers and opinions, but never takes middle ground on anything. Aquarius will never judge another person due to there live and let live policy, because she believes, as a humanitarian, that every human being is equal no matter who they are as a person or where they came from. Aquarius is verbally skilled in the art of manipulation, and is quick at adapting to any situation that appears before her, due to her being able to read the body language of others and change the situation in her favor. Aquarius is always finding things to change, as she sees boredom as her enemy, and sees anything new as an opportunity to shape it and change it. Aquarius can appear as if she knows everything on a topic do to her being an expert on manipulation, although she probably knows next to nothing on it. Aquarius is known to inflate her own ego and even make herself seem more important then she actually is, which can seem to come off as an inflated ego. Even she never creates an opinion of others, she does like to pick on people she sees as weak or dull-minded, but doesn't intend to cause harm, which most of the time can be taken that way, but deep down, she would never intentionally hurt anyone, as she has respect for every human being. Aquarius can sometimes be depicted as emotionless, due to the fact that she usually doesn't show much emotion, unless something turns in her favor.
Aquarius was born into a Muggle family in northwest China, but her parents gave her up for adoption after she was born, due to the law at the time. A little over 6 months later, she was adopted by an American couple named Gino and Joe Calder. They lived in the state of Idaho in the northwestern USA. Growing up, she was often teased by the other kids for not looking like either her fathers, and despite her fathers doing a reasonably good job at raising her, she often felt isolated from them and everyone around her for this reason. Thus, she desperately tried searching for a raison d'etre, a pursuit in life in which she could fully commit herself, but for years she was unsuccessful, until she was invited to the Salem Institute of Magic to be enrolled as a student.
Aquarius only spent a single year at the Salem Institute of Magic, due to the many Pure-blood that roamed the halls. They would constantly picked on her for having 2 dads and being Muggle-Born. The year ended up getting worse for her, and eventually a group of Pure-Bloods targeted her, and incited a duel with her. 4-on-1, she saw them as bad odds, and she was right. Although, she didn't blame them for what they did, but rather the situation. They ended up causing minor injures, which ended up causing her dads to pull her out of school. They then decided to move to England and enroll her in Hogwarts School of Witchcraft and Wizardry.
During her 2nd year, her first year there, she met 8 amazing people, that would later turn into 13, and would eventually be known as the Zodiac. Due to there differing personalities.
