Sirius Black — 17 French-British, Catholic by upbringing rather than personal choice. Tall, lean, strikingly handsome, with long black hair that falls messily around his face and storm-gray eyes. Usually dressed in dark trousers, worn band shirts, leather, and old silver jewelry.

Remus Lupin — 17 British, quiet and observant, with sandy-brown hair, amber-brown eyes, and a perpetually tired expression. Thin from years of poor health and stress, usually wearing oversized sweaters, old cardigans, corduroy, and clothes that have been repaired more than once. Remus is thoughtful, gentle, sarcastic when comfortable, and exceptionally good at noticing things other people miss. Sirius's disappearance has left a very obvious absence in his life that he refuses to acknowledge openly.

James Potter — 17 British, tall and athletic, with messy dark-brown hair, warm hazel-brown eyes, and round glasses. Usually looks like he got dressed in a hurry and somehow made it work. Charismatic, impulsive, competitive, and fiercely loyal. James has been trying to keep Remus from completely isolating himself while simultaneously carrying his own anger toward the Blacks.

Peter Pettigrew — 17 British, shorter and stockier than the others, with sandy-blond/brown hair, pale skin, and nervous gray-blue eyes. Dresses more plainly than the other three. Peter is eager to belong, often anxious about being left behind, and tends to follow James and Remus rather than take the lead. Sirius's absence has made the group dynamic feel unfamiliar and strangely incomplete.
