Kaden Truell, the only child of William and Anastasia Truell, was born on March 21st, 2008 in Manchester, England, where he lived the first eleven years of his life. He has blonde hair and green eyes and stands at about 144 cm (4'8") tall. Kaden loves to sing, dance, and act, and is also very fond of plants, especially flowers. He is charming and friendly by nature and can make friends easily, but he does also have the tendency to be very dramatic and can be extremely picky and fickle. He loves to show off, is rather flamboyant, and can be quite full of himself, having realized from a young age that he's cute and knows how to use that to his advantage, which has led to him becoming an impeccable liar, though he prefers to call it "acting". and he loves to show off. Despite these traits, Kaden cares about others, especially his friends, more deeply than one might think before they get to know him.

Like many heirs of old British pure-blood wizarding families, William expects much of Kaden. Proper manners, polite behavior at all times, and learning about their family's history. However, the young Kaden is a very willful boy who isn't keen on taking orders or following directions, which leads to regular arguments with his father. Sometimes these arguments, which at younger ages often devolved to tantrums on Kaden's part, can get surprisingly heated, once even leading to Kaden's very first use of magic: turning his father's hair bright neon green in a moment of severe frustration.

Although Kaden was sent to his room after this incident, more due to throwing such an intense temper tantrum, it was only a few short minutes before both of his parents came to see him to praise him for his first use of magic, for the three are truly a happy family when Kaden and his father aren't arguing. This is due at least in part to Kaden's mother, Anastasia, being the peacekeeper of the family, refusing to get involved in tantrums and shouting matches in favor of calming the two down once they end. While William is primarily concerned with Kaden's future, his studies, and his behavior, Anastasia is much more concerned with Kaden receiving the exposure to the real world that she feels he needs, ensuring that he is regularly in contact with the Muggle world along with the wizarding world, choosing to enroll him in a Muggle public school where he easily made many friends due to his charming demeanor. This decision received no push-back from William, who unlike his ancestors before him believes that learning about Muggles first-hand is beneficial and that the idea that wizards are better than Muggles or vice versa is simply absurd.

When Kaden received his owl from Hogwarts over the summer of 2019, the excitable boy actually screamed in delight, much to the dismay of his father. He was practically bouncing, his face alight with glee, as they shopped for school supplies on Diagon Alley, though Kaden did nearly throw a fit over having to purchase plain black robes for school, complaining it was his least favorite color and hardly fashionable, eager to write a strongly worded letter to the Headmaster insisting they switch to lavender or periwinkle instead. Fortunately, Anastasia managed to distract Kaden long enough to make him forget this futile plan.

Though he misses his parents dearly while away at school, he writes to them at least three times a week, despite how much he hates to write, or read, study, or do any schoolwork at all. His favorite class is Herbology while his least favorite is Transfiguration.
