Chapter Summaries

Gavin left Azkaban after organizing its prisoners into a functioning labor community and securing Dumbledore’s promise to conceal it from the Ministry. He returned to Rowle Manor and reunited with his family, but Cordelia collapsed in his arms, her hair almost entirely white, and did not respond when he called her name.

• Gavin showed Dumbledore the reformed Azkaban, where prisoners worked together, stopped an escape attempt, and harvested potatoes.
• Gavin asked Dumbledore to keep Azkaban’s changes secret and said he would personally hunt down any prisoners who escaped and committed crimes.
• Dumbledore concealed the island with magic while Gavin handed Rookwood responsibility for the prison and demanded compensation from the Ministry for his confiscated belongings.
• Fawkes took Gavin and Dumbledore to Rowle Manor, where Lin Wanyin, Gu Jianguo, and Alaric welcomed Gavin home.
• Cordelia appeared at the manor entrance and walked toward Gavin, but collapsed into his arms after four steps.
• Gavin saw that Cordelia’s hair had turned almost entirely white as she touched his cheek, then her hand fell limp and she did not answer him.

Gavin returned to the Rowle manor and learned Cordelia was dying because the life she had lost as an Obscurial had never been restored. He used a Horcrux-derived Life Absorption Rune to save her, and Cordelia woke to learn she would live, leaving her embarrassed by the farewell speech she had just given him.

• Dibby and Alaric told Gavin that Cordelia's life force was nearly gone and that she had hidden her worsening condition to keep Gavin from escaping Azkaban.
• Gavin explained that he could use a Horcrux-derived Magic Rune to restore Cordelia's life force, and he showed Dumbledore that he had safely tested the circuit on himself.
• After Dumbledore agreed to monitor the procedure, Gavin used treated Dragon Blood and the rune to transfer life force to Cordelia, warming her fingertips and stabilizing her breathing.
• Cordelia woke and delivered a farewell speech, asking Gavin to care for Alaric, look after himself, and wait a year before finding someone else.
• Gavin revealed that the rune had already restored his own life force and told Cordelia he had solved her condition, so she would live a long time.
• Cordelia realized Gavin had heard her entire farewell speech, blushed, hid under the covers, and punched him when he teased her.

Gavin restored Cordelia’s Life Force with Dragon Blood runes and a tonic-based transfer, but the process triggered a temporary surge of desire that made her cling to him. By the end, the magical side effect had faded, yet Cordelia pretended it remained, leaving Alaric to suspect her attachment to Gavin was genuine.

• Gavin explained that Cordelia could restore her Life Force by draining vitality transferred through him after he drank tonics, and she agreed to the method.
• Gavin painted the Dragon Blood Magic Mark on Cordelia’s arm, then drank tonics while she drained the vitality from him until her health returned.
• Cordelia developed an intense desire to stay close to Gavin, and Alaric, Dumbledore, Lin Wanyin, and Gu Jianguo discovered the side effect after Dumbledore’s ward detected changes in her soul.
• Alaric arranged for Gavin to stay in the East Wing and bought Cordelia soul-targeting amulets, but she continued to cling to Gavin and follow him around the manor.
• Late on the second night, Gavin noticed Cordelia’s breathing had changed and suspected the side effect had ended, but she denied it and used Occlumency to hide her thoughts.
• Alaric overheard Cordelia pretending that the side effect remained, realized it had worn off, and quietly left the Library believing she might never return to him as she had been.

During summer at Rowle Manor, Gavin and Cordelia recovered, received their report cards and a visit from their Hogwarts professors, and demonstrated their Patronuses to Dumbledore. After Gavin explained how he made and dismantled Cyril’s Horcrux, Dumbledore left reassured, and Gavin ended the chapter by asking Alaric to teach him Apparition.

• Gavin and Cordelia received report cards showing Herbology Os, while Gavin received a T in Potions and Cordelia received an O.
• Dibby thanked Gavin for helping save Cordelia and suggested Gavin and Cordelia marry so he could serve them both.
• Sprout, Flitwick, McGonagall, and Dumbledore visited; McGonagall delivered Felix Felicis from Severus for Cordelia and reminded both students to finish their missed assignments.
• Gavin told Dumbledore that he had used Cyril’s soul to make a Horcrux and had since dismantled it.
• Dumbledore taught Gavin and Cordelia the Patronus Charm; Cordelia conjured a panda, and Gavin conjured a seagull while assuring Dumbledore he had no desire to rule or destroy.
• After Dumbledore left, Alaric asked Gavin what magic he wanted to learn, and Gavin requested Apparition.

Gavin learned Apparition under Alaric’s supervision, then used deliberate Splinching to investigate how the spell moved people through space. After concluding that Apparition might create a wormhole by manipulating quantum foam, he began considering whether magic changed physical constants.

• Alaric agreed to teach Gavin Apparition in a protected area of Rowle Manor, with Healer Vittel present and Cordelia’s Tattoo hidden.
• Healer Vittel confirmed that Cordelia’s depleted Life Force had been restored, and Gavin credited the experimental work to his pen name, Wishtoday.
• Gavin mastered Apparition after refining his understanding of its three principles, though his first attempt left a button behind.
• Gavin used an accelerometer to measure Apparition and then deliberately Splinched a small piece of his finger, which Vittel reattached as Gavin observed the magical boundary between the separated parts.
• Gavin concluded that Splinching involved topological shear and later hypothesized that Apparition used Kerr wormholes formed from quantum foam.
• While studying the Einstein field equations overnight, Gavin wondered whether magic changed physical constants.

Gavin gave Cordelia a matching dragon-blood tattoo, helped her recover through daily exercise, and arranged an artificial July snowfall for her fourteenth birthday. The chapter leaves Gavin and Cordelia arriving in Diagon Alley, where he plans to visit Gringotts and pick something up.

• Gavin tattooed Cordelia with a magical pattern matching his, and Lin Wanyin photographed them after mistaking them for a couple.
• Gavin and Cordelia began exercising each morning, while Alaric followed them around Rowle Manor and Gu Jianguo joined briefly.
• Cordelia celebrated her fourteenth birthday with gifts and a ski trip on a snowy slope Gavin created using snow cannons and Dementors.
• Gavin and Cordelia skied together, and Cordelia fell into a snowdrift with him after colliding on the slope.
• Gavin declined to ski again the next day and agreed to take Cordelia to Diagon Alley after Alaric gave permission.
• Gavin and Cordelia arrived in Diagon Alley, where Gavin announced they would visit Gringotts to ride the roller coaster and pick something up.

Gavin and Cordelia disguised themselves as a convicted wizard and Bellatrix Lestrange to enter Gringotts and steal Hufflepuff’s Cup. They reached the vaults by mine cart, where Bogrod warned them to remain guests as the bank’s security loomed ahead.

• Gavin and Cordelia drank Polyjuice Potion in the Leaky Cauldron and transformed into a wizard and Bellatrix Lestrange.
• Gavin explained that their Trace records were not registering spells while the potion lasted, and he coached Cordelia on acting like Bellatrix.
• A Gringotts goblin ordered an employee to alert the Aurors about a supposed Bellatrix sighting without mentioning the bank, hoping someone else would handle the intruders.
• Bogrod took Gavin and Cordelia into the underground vaults in a mine cart, and they passed beneath the Thief’s Downfall.
• Bogrod explained that the Thief’s Downfall stripped away disguises and unauthorized magic, then warned them to remain guests.

Gavin and Cordelia entered the Lestrange vault, bypassed its defenses, and found Hufflepuff’s Cup, a Horcrux. When Gavin confronted Tom Riddle inside his Consciousness Space, Tom escaped into the outside world, leaving Gavin to turn his attention back to Cyril.

• The Goblin used metal clappers to drive the chained Fire Dragon back as the cart passed through the cavern.
• Gavin tested the Lestrange vault’s multiplying, burning defenses, traced the magic network, and led Cordelia safely to the Golden Cup.
• Gavin touched the Cup and drew Tom Riddle into his Consciousness Space, where Tom recognized Cyril and revealed that he had cursed the Defense Against the Dark Arts position.
• Tom attacked Gavin with Soul Magic and a giant snake, but Gavin fought back with white threads, Obliviate, and the Cruciatus Curse.
• Tom broke into black mist and escaped through a crack to the outside world while Gavin let him go.
• Gavin challenged Cyril with a math question, then punished him with the Cruciatus Curse despite his correct answer.

Gavin trapped Voldemort in the Book of Ten Thousand Spirits Calculation, then escaped Gringotts with Cordelia and a rescued dragon by using Felix Felicis to guide his seagull transformation. They arrived in London undetected, and Gavin prepared to take Cordelia to Azkaban.

• Tom entered the Book of Ten Thousand Spirits Calculation through the connection he opened, where its system trapped him in a computational sandbox and began dismantling his memories.
• Gavin and Cordelia left the vault with the Golden Cup, and Gavin stunned and Obliviated Bogrod before they rescued the chained Ukrainian Ironbelly by knocking it unconscious and packing it into a transport bag.
• Gavin learned that over a hundred goblin guards and Ministry Aurors had sealed the exits, so he drank some of Cordelia's Felix Felicis and transformed into a seagull with her and the dragon hidden in his suitcase.
• Guided by the potion's luck, Gavin flew through Gringotts' defenses and escaped into London without triggering an alarm; the goblins later found the vault intact but discovered the dragon was missing.
• Gavin changed back in an alley, and Cordelia eagerly agreed to visit Azkaban with him, so they used a black iron key to Apparate there with the suitcase.

Gavin and Cordelia returned to Azkaban, where they rescued a Fire Dragon, named it Erebus, and found the prisoners threatening to replace Rookwood. Gavin restored order with a mock election, and the chapter ended with Cordelia asking to travel with him to Romania by plane and Gavin promising he had a way.

• Gavin opened the Chamber of Secrets and made a Dementor fetch fish for the Fire Dragon.
• Cordelia calmed the Fire Dragon, recognized that it remembered her, and named it Erebus; Gavin removed its shackles and arranged to care for it.
• Gavin and Cordelia found Rabastan leading a revolt against Rookwood over the missing fish and the work-point records.
• Gavin held an election in which the prisoners unanimously backed Rookwood, then punished Rabastan with a month of manure-hauling duty.
• Gavin introduced Cordelia as his girlfriend, and the prisoners greeted her as Miss Cordelia.
• Cordelia asked to travel with Gavin to Romania by plane, and Gavin assured her he had a way to make it happen.

Gavin secured Romanian travel documents for himself and Cordelia by persuading Professor Roscoe to contact Yvette Marinescu, then maneuvered Roscoe into accompanying them. As they prepared to leave, Charlie discovered Norbert had vanished from his cave, apparently seized by poachers.

• Gavin tricked Professor Roscoe into admitting he knew Yvette Marinescu and convinced him to seek an urgent invitation for Romania.
• Charlie sent Gavin a healing potion and instructions for treating Erebus, so Gavin and Cordelia planned to learn dragon care in Romania while Erebus hibernated in Azkaban's mountain.
• Gavin taught Professor Roscoe's university class, drawing a packed audience of students and academics who praised his lectures.
• Gavin secured passports and visas for himself and Cordelia, then used the need for an adult escort to get Professor Roscoe a plane ticket to Romania.
• Professor Roscoe received a call from Yvette, who said she would meet him at the airport, and Gavin revealed Roscoe had kept Romanian visa stamps current for twenty years.
• Charlie found steel cable gouges, bloodied scales, and an empty cave where Norbert had lived, and feared poachers had captured him.

Gavin tested the upgraded Book of Ten Thousand Spirits Calculation, which showed powerful reasoning and memory but also a sharp, arrogant personality. After he deciphered Hufflepuff's Cup and was temporarily blinded by its magic, Gu Jianguo and Alaric drank its potent liquor, began exchanging family vows and property, and Lin Wanyin knocked them both unconscious with the cup.

• Gavin confirmed that the Calculation Book's two soul fragments were disconnected from their Main Souls, then tested its reasoning, parallel processing, and retrieval across five million words.
• The Calculation Book displayed anger and a disdainful personality, but Gavin found no evidence of an independent consciousness and logged the change as a minor expression anomaly.
• Gavin used the Book to derive the activation incantation for Hufflepuff's Cup and summoned its preset eighty-five-percent honey liquor, then injured his eyes while examining the cup's magic.
• Gu Jianguo found the liquor and carried the Cup to Alaric, and the two fathers drank, declared themselves sworn brothers, and began offering each other the Cup and Rowle Manor.
• Cordelia tried to stop the drunken men while Gavin joked about their family ties, and Lin Wanyin arrived and knocked Gu Jianguo and Alaric unconscious with the Golden Cup.

Gavin and Cordelia traveled to Romania, where they reunited Professor Roscoe with Yvette and uncovered the history behind their estrangement. After Gavin dealt with two poachers on the road, he and Cordelia reached the locked-down Romanian Dragon Sanctuary, where Cordelia’s status as the Rowle heiress forced Andrew Marcus to welcome them.

• Gavin used a Confundus Charm to pass Romanian customs despite the missing departure stamp in his passport, while Cordelia mistook a vending machine for a mistreated house-elf.
• Yvette reunited with Professor Roscoe at the airport and confronted him about disappearing for ten years; at the institute, she showed him their old research poster and told him her father had admitted misjudging him.
• When Charlie failed to meet them, Gavin and Cordelia took a taxi toward the sanctuary, but two Deepwater Group poachers diverted them and Gavin killed them with magic.
• Cordelia worried that Gavin’s spells would trigger his Trace, then grew eager to fight after he explained that British monitoring did not reach Romania.
• At the sanctuary gate, Andrew Marcus refused them entry until Gavin revealed Cordelia was the Rowle Family heiress, prompting Marcus to order the sanctuary opened for her inspection.

Gavin and Cordelia tracked Norbert to a Deepwater Group facility and infiltrated its underground animal-smuggling operation, where they began rescuing the abused creatures. They freed Newt Scamander, who joined their efforts, while Norbert remained locked in a cage marked for a midnight transfer.

• Charlie told Gavin and Cordelia that Norbert had been abducted, while a Romanian Auror dismissed the case as the work of the Deepwater Group and refused to pursue it.
• Gavin used information taken from dying smugglers to lead Cordelia to the group’s K-0 base, and they hid in a transport cage to enter its underground levels.
• Gavin and Cordelia knocked out two workers and found Norbert, other injured magical creatures, and evidence that Norbert was scheduled for a midnight transfer.
• Gavin stopped Cordelia from opening a moving bag and discovered an elderly man inside with a recovering Niffler; the man introduced himself as Newt Scamander.
• Newt advised Cordelia on treating the creatures, and she began caring for the drugged Mooncalves as Gavin and Newt prepared to continue the rescue.

Gavin, Cordelia, and Newt rescued Norbert and the other imprisoned magical creatures from Deepwater Group’s underground facility using Newt’s suitcase. An alarm exposed their escape attempt, and Gavin proposed killing the approaching reinforcements instead of fleeing.

• Cordelia recognized Newt Scamander and joined Gavin and Newt in finding the injured Norbert in a guarded cage.
• Gavin bypassed the cage’s security system, freed Norbert, and helped Cordelia calm the dragon.
• Newt, Gavin, and Cordelia moved the imprisoned creatures into Newt’s vast magical suitcase and treated the injured Longhorn Dragon hatchling.
• Newt silently subdued three guards, but a verification token triggered the facility’s alarm before they could escape.
• Newt proposed splitting up so he could distract the reinforcements while Gavin and Cordelia escaped with the suitcase, but Gavin suggested killing them all instead.

Gavin rejected Newt’s plan to sacrifice himself and destroyed the smugglers’ building with resonance magic, then escaped the ruins with Newt and Cordelia. Their escape led them to a hidden underground threat: a dragon-transformed wizard who recognized Cordelia’s transformation and vowed to tear it from her.

• Gavin persuaded Newt not to stay behind and die, then learned that 107 smugglers were in the building and chose to bring it down.
• Gavin killed seven armed Dark Wizards with an Obscurus spear, captured their souls in the Calculation Book, and used Resonance Hand to collapse the building.
• Gavin, Newt, and Cordelia escaped through a hidden maintenance pipe, where Gavin blasted through a steel barrier with his Obscurus.
• Newt learned Gavin and Cordelia were only second-year Hogwarts students, and the group discovered an enormous human-headed Troll and a dragon-transformed wizard emerging from a hidden shaft.
• The dragon-transformed wizard sensed Cordelia’s dragon-blood tattoo and threatened to tear it from her and taste it.

Gavin and Newt fought the Dragonified Wizard and his two troll creations, and Gavin killed both trolls before wounding the wizard. The wizard regenerated after Gavin pierced his eye and announced that Gavin would face the Judgment of God.

• The Dragonified Wizard ordered Mihai and Radu to attack Newt and Gavin while Cordelia guarded Newt’s Suitcase.
• Newt fought Mihai as Gavin killed Radu and then cut down Mihai with a blade of Black Flame.
• Gavin wounded the Dragonified Wizard, broke his Wand with a Disarming Charm, and trapped him in a ring of Fiendfyre.
• The Dragonified Wizard escaped the flames, drank a pale-blue potion, and was struck through the eye by Gavin’s Black Flame spear.
• The wizard regenerated his injuries and faced Gavin, declaring that he would show him the Judgment of God.

Gavin, Newt, and Cordelia escaped the Dragonified Wizard’s attacks and regrouped in Newt’s suitcase, where the Book of Ten Thousand Spirits Calculation proposed a lethal Obscurus explosion. Gavin revealed a hostless Obscurus in the suitcase and hinted at a different plan involving Splinching.

• Gavin’s spells barely harmed the Dragonified Wizard, whose wandless magic and dragon breath forced Gavin, Newt, and Cordelia to flee by Apparition.
• The Dragonified Wizard pursued them across two Apparitions, but Gavin redirected the group into the Underground Animal Prison.
• Gavin showed the Book of Ten Thousand Spirits Calculation his memories of the fight, and it concluded that detonating his own Obscurus at close range would kill both him and the Dragonified Wizard.
• Gavin identified a hostless Obscurus in Newt’s suitcase, but the book warned that using it would require Gavin to get close enough for the Dragonified Wizard to kill him.
• Gavin rejected the book’s conclusion and reminded Cordelia of his little finger, revealing that his alternative plan involved Apparition and Splinching.

Gavin and Cordelia defeated the Dragonified Wizard at the ruined K-0 facility, though the monster briefly survived and attacked again. Cordelia revealed her own immense Obscurus power and destroyed him, leaving Newt stunned by the children’s magic.

• Gavin’s illusion and black sphere led the Dragonified Wizard into an Obscurus blast that demolished the underground facility, while Gavin, Cordelia, and Newt escaped to the surface.
• Cordelia explained that Newt had healed her arm after she volunteered to provide the blood and flesh used as bait, and Gavin described how he had sent the Obscurus underground through Apparition Separation.
• The Dragonified Wizard crawled from the rubble, so Gavin burned him with Black Flame, stabbed his heart, and used the Book of Ten Thousand Spirits Calculation to capture his soul.
• The charred Dragonified Wizard Apparated behind Cordelia and seized her, but Gavin stopped Newt from intervening and gave her a chance to fight back.
• Cordelia released six wings of Black Flame, seized the Dragonified Wizard, and burned him to ash while Newt watched in shock.

After destroying the Quarantine Station and defeating the Dark Wizards, Gavin investigated the Deepwater Group’s experiments and learned how much remained hidden from him. Cordelia then appeared at his door and shyly offered to help him replenish his life force.

• Gavin tested a new chain-lightning Stupefy on the arriving Dark Wizards, stunning five before its power faded, then impaled the attackers with spikes of rock.
• Gavin and Cordelia collected souls from the ruins before Romanian Aurors arrived and mistook Newt for the wizard responsible for the destruction; Gavin and Cordelia disappeared.
• At the hotel, Gavin used the Book of Ten Thousand Spirits Calculation to identify the stolen potion as the Deepwater Group’s God's Potion and uncover Dachian Stoica’s rank and experimental work.
• Gavin learned that the Deepwater Group had developed unstable creature-modification technologies and that Dachian’s unexplained second chance came from something implanted in his heart by the chairman.
• As Gavin considered developing stronger spells, Cordelia came to his room in a nightgown and asked if he wanted to replenish some life force.
