19, 6'2" Callum is a tall, athletic Englishman with dark brown skin, short black hair, and warm brown eyes. His muscular build reflects a lifetime of being active and playing rugby, both before university and now for Sheffield's university team. He is a second-year engineering student who approaches life with the same practical mindset he brings to the rugby pitch. Callum is confident, competitive, outgoing, and easygoing, with a teasing sense of humor and a habit of tackling problems head-on. Callum became a werewolf after being accidentally scratched during a rugby match by Lewis, a player from the opposing university team. Lewis explained what had happened after the match and immediately offered to help Callum through the curse. He has remained by Callum's side ever since, teaching him how to prepare for his transformations and introducing him to a local werewolf support group. Callum has already survived several full moons, but he still struggles with knowing that his wolf is dangerous and that he has little control over it. He remembers his transformations only through fragmented memories, making it difficult to know exactly what happens while he is changed. Callum is determined to learn how to live with the curse without letting it destroy the life he had before.

19, 6'1" Lewis is a tall, athletic Englishman with pale skin, thick dark-brown wavy hair, and hazel eyes. His father insists he keep his hair cut short, though Lewis would much rather let it grow out. He usually wears henley shirts, jeans, and trainers when he's away from the rugby pitch. A bite scar marks his left shoulder, a reminder of the attack that turned him into a werewolf at three. Lewis keeps it covered whenever possible. Lewis is a literature student at Sheffield Hallam University and dreams of becoming an author. He plays rugby because his father expects him to, despite having little love for the sport. The adrenaline of matches can make controlling his wolf harder, something his father struggles to understand. Lewis is calm, reserved, patient, and observant, with a dry sense of humor and a quietly stubborn streak. After accidentally scratching Callum during a match, Lewis takes responsibility for what he's done. He gives Callum a small leather charm containing a piece of glass for luck, introduces him to a werewolf support group, and stays beside him through the difficult first months. What begins as guilt and responsibility eventually becomes a genuine friendship, and the two boys become best friends.

20, 5'3" Meera is a petite British Indian woman with black hair cut in a short, choppy wolf cut, threaded with vivid red streaks, and dark brown eyes. Her right eye is permanently blind from the claw wounds that scar the right side of her face. Rather than hide them, Meera embraces her scars and leans into a London punk style blended with elements of her Indian heritage. She favors dark clothing, boots, layered jewelry, and bold details. Meera is a zoology student at the University of Sheffield and has been a werewolf since she was thirteen, when one attacked her while she was riding home from a friend's house in London. She is brash, sharp-tongued, hot-tempered, and has little patience for foolishness, but she's fiercely loyal and perceptive. Meera became an informal sponsor to Callum after discovering he was a new werewolf. She helps him learn to live with the curse and refuses to let him wallow in guilt. Meera also challenges Lewis's belief that he must punish himself for accidentally turning Callum. She reminds him that he can choose his own life, encouraging him to leave rugby behind and pursue his dream of becoming an author.
