Background / History

Hermione enters Hogwarts as a highly prepared first-year and is sorted into Gryffindor. She becomes Irina Lowell's roommate; their shared interest in magic quickly develops into a close friendship. Hermione demonstrates the Glacier Spell during their earliest practice sessions, then learns Irina's specialized reversal technique through repeated casting. 38 39 40

Although strongly concerned with rules and House points, Hermione repeatedly risks herself for her friends. She substitutes for Harry during his illegal midnight duel with Draco Malfoy, defeating Malfoy, Crabbe, and Goyle with the Full Body-Bind Curse. 43 44 After Ron's criticism reduces her to tears, Irina stays with her in the girls' bathroom; the two are then trapped there during the troll incident. 46 47 Hermione is injured while facing Quirrell in the final chamber beneath Hogwarts after helping Harry and Irina reach it. 75 76

During her second year, Hermione works with Harry, Ron, and Irina to investigate the Chamber of Secrets. She proposes using Polyjuice Potion to infiltrate Slytherin House, but a mishap leaves her temporarily in a cat-like form and confined to the hospital wing. 109 128 She is later petrified during the Basilisk attacks. 133

By third year, Hermione receives a Time-Turner after enrolling in every available class. 180 Her faith in the Ministry's impartiality is shaken by Buckbeak's trial, and Irina helps her recognize the influence wielded by powerful families. Hermione ultimately reconciles with Harry and Ron after reporting Harry's Firebolt out of concern for his safety. 226 227

In fifth year, Hermione openly challenges Dolores Umbridge's theory-only Defense Against the Dark Arts lessons. She then initiates the Dark Arts Defense Group, recruiting Irina, Harry, and Linley as instructors and arranging its first secret meeting. 462 463 465 After graduating, she becomes Barty Crouch Sr.'s secretary while remaining an official member of the D.A. Army. 766

Personality

Hermione is exceptionally studious, competitive, and exacting. Even when she is nervous during first-year final examinations, she worries over points she may have missed; her strengths span nearly every academic subject. 73 She has read Newt Scamander's Fantastic Beasts and Where to Find Them three times and memorized its contents. 232

Her intelligence is matched by a strong protective instinct. She reports Harry's Firebolt because she fears it may be cursed, supports Hagrid and Buckbeak, and confronts Umbridge when the professor refuses to provide practical defensive instruction. 226 462 However, she can initially prioritize being correct over her friends' feelings; Irina persuades her to apologize to Harry and Ron over the Firebolt dispute. 226 227

Irina's influence broadens Hermione's perspective and magical ability. By fourth year, she is described as more capable and more able to weigh situations from a wider viewpoint than before. 358

Equipment / Items

• Time-Turner — issued through Professor McGonagall after Hermione registers for every class. 180
