Chapter Summaries

Anton explored Hogwarts’ lesser-known competitions and clubs, then continued researching magic that could detect and control emotions, will, and memories. He moved his experiments to a fortified basement under the Cabin, where he tested a deadly sound spell on a Runespoor and began trying to reduce its power.

• Anton reviewed records of Hogwarts competitions and found that Snape’s mother had captained the Gobstones Team and that students had competed for the Barnabas Finkley Charm-Casting Award.

• Anton moved his research underground, reinforced the basement, and trapped Little Snake there under a Bubble-Head Charm.
• Anton used a piercing sound spell on a Runespoor, killing it instantly, and recorded that he needed to weaken the spell so he could control the soul’s black lines instead.

Anton tested his Banshee Wail on Runespoors, then went to the Forbidden Forest to find cheaper test subjects and encountered a powerful Werewolf. Meanwhile, Voldemort remained trapped in the Snake Pit and resolved to wait for a chance to escape.

• Anton found that his lower-frequency Banshee Wail still killed a Runespoor and decided to seek other test subjects in the Forbidden Forest.
• Voldemort possessed a Runespoor and tried to escape the Snake Pit, but the Elephant-Eating Vine and stone walls kept him trapped.
• A pure-blooded Werewolf knocked Anton from his broom and tore through his robes, but his Dragon Hide protected his skin.
• Anton transformed into a giant Werewolf and charged the injured creature, eager to fight it.

Anton subdued a werewolf and experimented with a Banshee Wail, then studied his research for a way to alter its soul and exchange information between humans and werewolves. He took the werewolf back to that morning and prepared to examine it through the River of Time.

• Anton trapped the werewolf beneath clay, used a Banshee Wail to twist its soul, and stopped when he found the spell too crude to control the distortion.
• Anton reviewed his research on werewolf transformation, venom, the Blood Curse, and his discovery that humans and werewolves could exchange information.
• Anton decided to try giving the werewolf a human head and used his Time-Turner to take it back to that morning.
• Anton saw that the werewolf's Soul Black Lines had become loose and fluffy in the River of Time, then prepared to examine it.

Anton studied how his Biomimicry Charm rearranged Soul Black Lines, then used a Mandrake’s cry to reverse a Werewolf’s transformation. He turned the Werewolf into a woman, but a scream and approaching footsteps interrupted him as he hid in the Forbidden Forest.

• Anton compared the Werewolf’s Soul Black Lines with those of his other forms and discovered that his transformations connected threads from the Deathly Hallows Symbol into temporary bloodlines.
• Anton concluded that his shattered soul could only rearrange its existing threads, not create Soul Black Lines for someone else.
• Anton used a Mandrake’s cry to make the Werewolf’s human and magical-creature information flow together, gradually reversing its transformation.
• Anton watched the Werewolf become a woman and was stunned by the result.
• After hearing a scream and footsteps approaching, Anton put the woman into the Snuffbox and transformed into a Color-Changing Windbird to hide in a tree.

Anton discovered that a Death Eater had used Polyjuice Potion to impersonate Seamus Finnigan and hunt for Unicorn blood in the Forbidden Forest. He alerted Dumbledore, who found the real Seamus imprisoned in a suitcase beneath his bed, while the impostor remained at large.

• Anton watched the impostor, disguised as Seamus, trap a Werewolf and reveal his plan to make a Potion from Unicorn blood for the Dark Lord.
• Anton realized the impostor had infiltrated Harry Potter's dormitory and used the Time-Turner to return to the present.

• Dumbledore opened the suitcase beneath Seamus's bed and freed the real Seamus, who said a middle-aged man had tied him up and taken his hair.
• Dumbledore sent Seamus and Dean to the Hospital Wing and summoned storm clouds as he looked out over the school.

Dumbledore and the professors investigated a suspected Death Eater at Hogwarts, while Anton revealed that he had captured the werewolf from the Forbidden Forest and transformed her into a woman. Anton declared his experiment complete and left Snape responsible for her as the search for the infiltrator continued.

• Dumbledore summoned the professors after a suspected Death Eater infiltrated Hogwarts, and they questioned Anton about being out at night.
• Hagrid warned that the werewolf had been drawn toward the school, and Anton admitted he had captured it.
• Anton released the captive from his Snuffbox, and Flitwick immobilized her before she could attack Snape.
• The professors discovered the captive was a woman, and Anton explained that he had transformed the werewolf into a wizard-like form.
• McGonagall recognized traces of Animagus magic, inspiring Anton to consider further research into the transformation.
• Dumbledore focused on the Death Eater investigation, leaving Snape responsible for the woman after Anton said his experiment was finished.

Hogwarts staff used the Marauder’s Map to search for the hidden Death Eater and Peter Pettigrew, but neither appeared on it. Dumbledore left to investigate whether Tom was still at Hogwarts, while Snape remained with the Werewolf woman.

• McGonagall rejected Hagrid’s suggestion to have students search for suspicious behavior, and Dumbledore explained why Hogwarts could not safely suppress all magic.
• Lupin revealed that he, James, Sirius, and Peter had made a map showing everyone’s names and locations, and Anton said Fred and George owned it.
• Fred activated the Marauder’s Map, and Dumbledore tested its ability to show people protected by an Unplottable Charm.

• McGonagall, Sprout, Flitwick, Snape, Lupin, and Hagrid left to check the grounds and Forbidden Forest, while Dumbledore departed to find out whether Tom was at Hogwarts.

Fred and George planned to invent a way to detect injuries, but their discussion about using Potions to alter creatures’ Traits gave Anton an idea about the female Werewolf’s transformation. Anton rushed to the Underground Chamber to investigate, while Hannah and Neville discussed growing a house-making Elephant-Eating Vine.

• Fred and George decided to invent something impressive and considered using Puffskeins to detect injuries.
• Anton suggested that an injured Death Eater could be found with a device that detected wounds, even if he used Polyjuice Potion.

• Anton hurried into the Underground Chamber, taking his Notebook with him.
• Hannah offered to help grow Elephant-Eating Vines, and Neville proposed breeding one that could grow a small house.
• Fred and George frightened Neville by pretending the cabin’s vines might attack him, but Hannah encouraged him to help improve the vine and he agreed.

Anton tested how Werewolf blood affected a Runespoor, discovering that its transformation began with new hearts and lungs that quickly burst. He then visited the Restricted Section for books on the body, where Madam Pince gave him a dangerous-looking volume to study.

• Anton used a Time-Turner to study a Runespoor transformed into a rabbit, then sketched the creature’s changing Magic Images and Soul Black Lines.
• Anton fed Lupin’s post-transformation blood to a Runespoor and saw its Soul Black Line change before the creature exploded.
• Anton used Perception Theft to sense another Runespoor’s body as it developed new hearts and lungs that burst during its transformation.

• Madam Pince limited Anton to borrowing one book at a time and gave him Chop and Mash, One Finger at a Time.

Andy read a dangerous book about the links between a Wizard’s body, soul, and Magical Power, then questioned how its theories applied to his own transformations and fractured soul. The chapter ended with Andy standing by the Black Lake, wondering whether he belonged to his past life or the Wizarding World.

• Andy prepared a Wakefulness Potion and followed the book’s instructions to reveal and safely open Chopping and Mashing, One Finger.
• Andy read the author’s experiments on bodily changes, House-elf fingers, and the connections between body, soul, and Magical Power.
• Andy revised his Trinity Theory and wondered why his Animagus forms and other soul changes had not affected him as the book’s theory predicted.
• Andy used a mirror to shift between his previous-life appearance and his current appearance, then questioned whether his uncertain identity had contributed to his fractured soul.
• Andy went to the Black Lake as November brought snow and reflected that, four years after crossing over, he needed to decide whether to become part of the Wizarding World.

Anton used a self-inflicted Confundus Charm to explore his identity, then captured Barty Crouch Jr. and began an experiment to create a new kind of Animagus. After the spell wore off, he questioned whether Anton or Anthony was his real self and introduced himself to Barty as Anton.

• Anton altered his soul with a timed Confundus Charm and presented himself as Anthony Weasley, a wizard who had survived Dark Wizard Fiennes and lost his memory.
• Anthony defeated a pursuing wizard with spells, identified him as a suitable experimental subject, and brought him to Cabin.
• Anthony confirmed the captive was a Death Eater and used Barty Crouch Jr., Runespoors, Mandrake Black Threads, and Potions in an experiment to create a new kind of Animagus.
• As scales grew on Barty's hand, Anthony questioned who he was, recognized the Confundus Charm he had placed on himself, and removed it.
• Anton wondered whether Anthony was only a constructed identity, cast the Cruciatus Curse on himself again, and revealed his black-haired appearance to Barty.
• Anton told Barty that his name was Anton, then realized he had spoken in his mother tongue and repeated his name in English.

Anton tried to save Barty after his hand transformed into a snake and repeatedly exploded, using healing magic and blood from Runespoors to keep him alive. He decided to complete Barty’s Animagus transformation and headed for Hogwarts Castle to find the Thunder of the Mind.

• Barty’s snake-like palm exploded, and Anton’s repeated attempts to heal it caused it to regrow and explode again.
• Anton used the Life Crawl spell on three Runespoors to restore Barty’s strength despite his severe blood loss.
• Anton concluded that he should complete Barty’s Animagus transformation, using a Ray of Sunshine and the required ingredients.
• Anton petrified Barty, packed him and supplies into a suitcase, and hurried toward Hogwarts Castle to seek the Hufflepuff legacy’s Thunder of the Mind.

Anton experimented on Barty Crouch Jr. beneath the Thunder of the Mind and discovered how bloodline memories related to Animagus transformations and magical afflictions. He also realized that objects he had placed in his Soul Shell had confused his sense of self, so he removed Dumbledore’s Horcrux and sealed it in the Merpeople’s Song Pendant.

• Snape caught Anton carrying a Suitcase at night, and they agreed not to mention seeing each other.
• Anton brought Barty Crouch Jr. to the Thunder of the Mind, restrained him, and examined his Soul Black Lines.
• Anton saw that Barty’s Soul Black Lines formed the Deathly Hallows Symbol and found Runespoor memories awakening within him.
• Anton concluded that Animagus transformations awakened species traits and that concealing those memories might cure Nagini’s and Lupin’s conditions.
• Anton realized that Tom’s Remains and Dumbledore’s Horcrux had confused his Ego, removed Dumbledore’s Horcrux, and placed it in the Merpeople’s Song Pendant.

Anton destroyed Tom's Remains, then used the Philosopher's Stone to give another version of himself a body and complete his soul. The Stone crumbled to dust, while Voldemort watched helplessly and the Runespoor that had been Barty Crouch Jr. swallowed the other Runespoor.

• Barty Crouch Jr. awoke and reached for his Wand, but transformed into a gigantic Runespoor and was bound by Anton's ropes.

• Anton reflected on his new identity as Anthony Weasley before finding Barty Crouch Jr. transformed into a Runespoor.
• Anton restrained the Runespoor, cast A Ray of Sunshine on it, and carried it away in his Suitcase.
• Anton released Barty Crouch Jr. in an Albanian forest and flew back toward Hogwarts on a Thestral.
• Anton considered the extraordinary speed of magical flight and sketched the Thestral's complex Magic Image to study its flying ability.

Anton enjoyed flying his Thestral, then returned to researching a cure for Nagini, Anna, and Lupin by removing their memories of Fantastic Beasts. He persuaded Madam Pince to lend him dangerous Restricted Section books, though she warned him about Dark Magic.

• Anton flew his Thestral over the sea, through the woods, and into the clouds, delighting in its speed.
• Anton concluded that curing Nagini, Anna, and Lupin required erasing their memories of Fantastic Beasts, and rejected the Memory Charm as insufficient.
• Anton explained to himself that Memory Charms altered recalled memory images rather than erasing memories stored in the soul, and considered using Potions instead.
• Anton asked Madam Pince to lend him books about brain dissection and a potion involving poison, but she questioned how they related to his work on Dumbledore.
• Anton defended preserving dangerous knowledge and argued that studying Dark Magic did not automatically make someone evil.
• Madam Pince agreed to lend Anton the books because he had Lockhart's signature, but warned him that Dark Magic could turn someone bad.

Anton studied dangerous potion research while George and Fred asked the Cabin to lend them money to buy Ron a wand for Christmas. After everyone agreed, Anton, Neville, and Hannah set off to visit Ron at Hagrid’s Hut.

• Anton read about potions that altered instincts and the theory that ancient potions affected the soul, recording his research in several Notebooks.
• Anton heard that Ron’s broken Wand had caused his spell to rebound and make him vomit slugs after Draco insulted Hermione.
• George and Fred asked Anton, Neville, and Hannah to lend money from the Cabin’s funds so they could buy Ron a wand, promising to repay it from their Puffskein business.
• The Cabin agreed to lend the money, and George and Fred left for Quidditch training.
• Anton, Neville, and Hannah decided to visit Ron at Hagrid’s Hut.

Anthony studied Ron’s slug-vomiting spell, brewed a potion that cured him by removing false memories through its fumes, and then offered him a spare wand. Ron accepted, grateful to Anthony for treating him like family.

• Anthony found Ron vomiting slugs in Hagrid’s Hut and offered to brew a potion to help him.
• Anthony took Ron to his cabin, where Hermione questioned his unusual potion recipe and its ingredients.
• Anthony exposed Ron to the potion’s yellow-green fumes, and Ron stopped vomiting slugs.
• Anthony concluded the experiment supported his research into removing Lupin’s Werewolf Venom by targeting memories.
• Anthony showed Harry, Ron, and Hermione seventeen spare wands and invited Ron to choose one.
• Ron thanked Anthony after Anthony told him he was his cousin and did not need to be polite.

Anton and Snape spent the day revising Anton’s complex potion recipe, developing a preliminary version that could be administered both by inhalation and by drinking. After McGonagall revealed that Willocks had been expelled as a Ministry spy and Lupin had covered Snape’s class, Anton suggested Alex Fiennes as a Potions teacher.

• Snape analyzed Anton’s potion recipe, corrected its ingredients and methods, and helped improve its stability and effectiveness.
• Anton persuaded Snape to add Daisy petals, Dew, and Ganpu Kumquat Fruit Flesh to improve the potion’s scent and taste.
• Anton told Snape he had treated Ron by having him inhale the potion, and they considered splitting the treatment between inhalation and drinking to reduce its cost.
• Anton and Snape researched the potion from morning until dusk, finalized a preliminary recipe, and began preparing its ingredients.
• McGonagall told Snape that Willocks had been expelled as a Ministry spy and that Lupin had covered Snape’s class.
• Anton recommended his teacher Alex Fiennes as a replacement Potions teacher, and Snape agreed that Fiennes was qualified.

Anton and Snape tried to revise a Potion for treating Werewolf Venom and the Blood Curse, but its ingredients and brewing depended on emotions neither of them could provide. After a week of failed revisions, Anton gained inspiration from his Runespoor research and devised a Potion that could turn Wizards into rational Werewolves.

• Anton and Snape discovered that their Potion recipe required a pure-hearted, innocent, optimistic brewer, and Snape recalled that Lily might have met the requirements.
• Anton and Snape spent a week revising the recipe while balancing schoolwork and staying awake with bitter Stamina Potions, but none of their revisions improved it.
• Anton gained a new perspective while looking at the world upside down and wrote a recipe for a Potion that could create Werewolves who retained their reason during the full moon.
• Anton explained that his recipe drew on experiments showing that Werewolf Venom spread from the heart and affected the heart and Lungs.
• Snape praised Anton's Potion and encouraged him to keep pursuing Potions knowledge, and Anton looked forward to his future.
