Background / History

Anna is the daughter of Rosier and Nagini. Her childhood was shaped by Nagini's Blood Curse: when Nagini transformed into a giant snake and attacked in a state of predatory madness, Rosier believed he was saving Anna and struck Nagini down. Anna was subsequently told that her mother had died in a snake attack. 44

She lost thirty-six years while frozen in magic. Before even undergoing a magical awakening, Anna inherited Pedro the Goblin's Time-Turner technology and completed a massive time machine whose scale exceeded anything the Ministry's Department of Mysteries could create. 39 40

After traveling thirty-eight years into the past with Anton, Anna uncovered the truth of Nagini's fate through Pedro's Goblin Eye memories. Although devastated by what she witnessed, she insisted on seeing the full truth and resolved to save her mother. 43 44 She participated directly in the attempt to administer a cure to Nagini, only for Nagini to push her away to protect her during the transformation. 47 The group's later intervention ultimately saved Nagini, allowing Anna to be reunited with both parents. 50 356

Mr. Rosier later removed Anna from Durmstrang and arranged her transfer to Hogwarts, judging Durmstrang too stagnant and aristocratic for a wizard of her potential. 568

Appearance

Anna is usually presented as carefully groomed and elegantly poised, reflecting her Rosier upbringing. She keeps her head level while walking rather than looking at the ground, and initially carries herself with the reserved formality of a young noblewoman. 29

• Deep emerald eyes. 47 751
• Wore a loose cloak trimmed with silvery fur upon arriving at Hogwarts for the Inter-School Quidditch League. 353
• Can assume a twelve-foot giant-python form through her Blood Curse. 356
• Has learned advanced Human Transfiguration from a future version of herself, allowing her to alter her apparent age and physique. 636

Personality

Anna initially appears quiet, proud, restrained, and meticulously polite. Her disciplined upbringing leaves her outwardly composed even when she is angry or grieving; after learning her father lied about Nagini's death, she demanded the truth without losing her manners. 29 44

Beneath that restraint, she is intensely curious and patient with machinery. She can spend long periods adjusting intricate Time-Turner components, pursuing research, or working through the implications of Anton's magical theories. 155 868 Her time travel has also made her more adventurous and ruthless than her refined manner suggests. She sees dangerous temporal branches as “treasure chests” to be explored and is willing to use lethal force when she judges it necessary. 790 799 837

Anna is deeply loyal to Anton and protective of his interests. Though she speaks little in the Cottage's major discussions, her contributions are consistently consequential. 609 959

Abilities & Skills

Time Magic and Time-Turner Engineering

Anna's defining field is Time Magic. She inherited Pedro's Time-Turner knowledge and built a large-scale Time-Turner before her magical awakening. 39

• Travels through the River of Time and can encounter alternate versions of herself. 834
• Uses time travel to gain years of additional research time without the same amount of time passing for others. 836 1160
• Developed a contained time-slowing device that can extend one hour into four, though it cannot affect a large area. 872
• Her unusual temporal state is described as a superimposition of human and goblin bloodlines, enabling her to use Goblin secret arts that ordinary wizards cannot learn. 837
• Time travel exposes her to hostile or unstable temporal branches, including Auroro. 836 837

Blood Curse Transformation

Rather than removing Anna's Blood Curse, Anton helped her tame it as a controllable inheritance. Her transformation is considered deeper than an ordinary Animagus form. 356 362

• Transforms into a giant python approximately twelve feet long. 356
• Her snake form is extremely fast, physically powerful, venomous, resistant to magic, and capable of Parseltongue. 356
• Can consciously control her transformations as a Blood Curse Orc. 362
• Uses Anguish Eater's transformations and Soul Black Threads as part of her training in controlling magical changes. 356

Combat Magic

Anna is a capable combatant despite her refined demeanor. At Durmstrang, she was known as a “Three-Stage Wizard” and claimed particular proficiency with the Severing Charm, counter-curses, and Healing Spells. 672

• Cast a Patronus Charm to counter Auroro's Obscurus form. 837
• Used Evil Spirit Banishing repeatedly during her confrontation with Auroro. 837
• Fights with the decisiveness of an experienced time traveler, prioritizing action over argument when threats cannot be resolved peacefully. 799 1007
• Practices spell-enhanced archery, combining athletic-vision magic, arrow acceleration, and freezing effects. 601

Alchemy and Magical Devices

Anna combines Goblin Alchemy, Muggle science, and Anton's magical theory in her own research.

• Modified the Magic Mirror to receive information from Earth while on the moon. 1123
• Pursued a magical instant-messaging device using Spirit Body, Tree, and Veil theories. 868 904
• Researches interstellar Magic Mirror alchemy and soft-glass materials for space habitats. 1084
• Designed the Moon Palace, a stable lunar habitat intended to function even where magic is absent or limited. 1148 1160
• Struggles with conventional Transfiguration at school, despite her exceptional aptitude for devices and temporal magic. 355

Equipment / Weapons / Items

• Time-Turner — A nested, multi-layered device Anna uses to enter the River of Time. 834
• Anguish Eater Rabbit — A Dark Magic creature given to her by Anton; it can transmit memories and messages through a collective River of Memories. 355
• Hookah Skull — Used with the Eye of the Wizard potion and Pedro's Goblin Eye art to examine Nagini's memories. 43
• Magic Mirror — Modified by Anna for long-distance and Earth-to-moon communication. 1123
• Wand — Used for her combat, Time Magic, and technical spellwork. 837

Relationships

• Anton Weasley — Anna's closest companion, research partner, and boyfriend. He supports her through the truth of Nagini's death, helps her control her Blood Curse, and serves as her temporal anchor. 47 356 609 836
• Rosier — Her father. He concealed the truth of Nagini's death to protect Anna, later reconciled with her after the family's temporal ordeal, and arranged her transfer to Hogwarts. 44 50 568
• Nagini — Her mother. Anna's determination to understand and save Nagini drives her earliest time-traveling arc. 43 47 356
• Pedro the Goblin — Her maternal grandfather and a guardian bound by an Unbreakable Vow to care for her; Anna inherited his Time-Turner technology. 39 42 43
• Remus Lupin — A trusted family figure whom Anna calls “Uncle Lupin.” 39
• Hannah Abbott — A close Cottage friend and fellow researcher. Anna comforts Hannah, collaborates with her on projects, and shares responsibility for the Cottage's work. 879 1048 1143
• Auroro An — An Obscurus linked to Anna's timeline and seemingly a possible past version of her. Anton's Life Existence mapping identifies Auroro as an independent entity rather than Anna herself. 836 837

Story Role / Major Arcs

Lost Years and Nagini's Rescue

Anna uses her self-built Time-Turner to return to the period before Nagini's death. With Anton and Pedro, she investigates the Rosier manor, learns Nagini's true identity and fate, and attempts to save her mother without altering the memories of her younger self or Rosier. 40 43 47

Taming the Blood Curse

After Nagini is saved, Anna learns that she herself carries a powerful Blood Curse transformation. Rather than accept a risky cure, she chooses to develop control over it with Anton's guidance and Anguish Eater's assistance. 356 362

Hogwarts and the Cottage

After leaving Durmstrang for Hogwarts, Anna becomes one of the Cottage's core members. She develops her combat ability, magical-device expertise, and role as Anton's most consistent confidante. 568 601 959

River of Time and Auroro

Inspired by Anton's creation of Sanctuary Tower, Anna enters the River of Time to advance her own path. She spends years studying in preserved non-magical timelines, encounters many possible future selves, and ultimately confronts Auroro, an Obscurus connected to her temporal branches. 834 836 837

Lunar and Interstellar Research

Anna's later work shifts toward practical infrastructure for the next era of wizarding exploration: magical communications, Earth-to-moon Magic Mirror transmission, space-habitat materials, and the Moon Palace. 904 1084 1123 1160
