• Borgin sent John Mir through a Vanishing Cabinet to meet five concealed backers, and John Mir told them about the new potion.

John Mir warned Mister Mystery that news of the new Wolfsbane Potion threatened their plans, but Vaughn Weasley launched a surprise attack on the meeting in Borgin's basement. Vaughn pinned John Mir and overwhelmed the five backers, who began planning a desperate escape.

• John Mir told Mister Mystery that Joseph François had learned about the new Wolfsbane Potion through Matthew, and Mister Mystery asked whether Mir could act that night.

Harry, Ron, and Hermione learned that an Occamy’s stolen young had caused chaos in the camp, while the Daily Prophet reported Vaughn’s breakthrough in the Liverpool werewolf murders. At the Wizengamot, Vaughn accused prominent pure-blood families of conspiring behind the killings and protests, and the session recessed before Rufus Scrimgeour brought Amelia the interrogation results.

• Amelia recessed the Wizengamot session, and Rufus Scrimgeour arrived in her office with the results of John Mir’s interrogation.

Amelia reviewed John Mir’s memories with Scrimgeour, who suspected Vaughn had fabricated the list and urged an investigation by the Memory Modification Department. Vaughn explained his strategy to Amelia, who recognized that the list was meant to force hidden conspirators to expose themselves and pull the wavering faction into conflict; she and Vaughn ended by agreeing to involve Obliviator Headquarters in the investigation.

• Scrimgeour told Amelia that John Mir’s memories implicated a hooded figure called Mister Mystery in stirring up the North American werewolves, but offered no proof of the figure’s identity.
• Scrimgeour argued that Vaughn might have planted the list in John Mir’s mind and asked Amelia to bring in the Memory Modification Department, but she refused to risk John’s safety or involve a department she distrusted.
• Vaughn admitted to Amelia that he had fabricated the list to redirect attention from escalating werewolf-wizard tensions and to provoke the real masterminds into making the list seem credible.
• Amelia realized that Vaughn’s list was designed to create suspicion among pure-bloods, the wavering faction, and their opponents, ultimately pushing the wavering faction toward Dumbledore’s side.
• Amelia asked Vaughn about the murder of Alexander and Taylor and whether François was responsible; Vaughn said he had sent people to investigate North American werewolf settlements.
• Amelia told Vaughn that Scrimgeour had proposed having Obliviator Headquarters review John Mir’s memories, and Vaughn agreed that a third-party investigation could share responsibility.

As the Wizengamot descended into a brawl over Vaughn Weasley’s list of conspirators, Scrimgeour learned that John Mir had died during a memory examination and suspected Vaughn was responsible. Meanwhile, François sailed from Liverpool toward Ireland as bait to lure Fenrir Greyback, and he saw news about John Mir in an evening paper.

• Wizengamot members named on Vaughn’s list argued over the accusations until a fight broke out, while Scrimgeour’s Aurors let the brawl continue.

After John Mir died in Ministry custody, suspicion over Vaughn Weasley's list set pure-blood families against one another, while Shafiq and Russell Lestrange moved to distance their families from the scandal. At Hogwarts, Harry learned about the Lestranges’ role in Neville’s parents’ torture, and Hermione focused on improving her Potions skills instead of worrying about Vaughn.

• François read that John Mir had died after attacking an Obliviator, while Ministry employees suspected he had been silenced to protect families on Vaughn Weasley's list.
• Arthur Weasley worried that Vaughn was in danger as the Wizengamot erupted into brawls between families named on the list, and Russell Lestrange struggled to control the dispute.
• Shafiq admitted to Russell Lestrange that he had leaked the list to the Evening Prophet and invited him to join an interview distancing families absent from it.
• Harry asked Ron and Neville about the Lestrange and Shafiq families, and Ron explained that the Lestrange Brothers and Bellatrix Lestrange had tortured Neville's parents.
• Hermione joined Harry and Ron with several advanced Potions books and said she was concentrating on improving her Potions skills rather than discussing Vaughn's troubles.

Hermione explained that the public release of the pure-blood list had made Vaughn’s political work temporarily complete, while the international Potions exchange program promised to reconnect magical schools. Back at Hogwarts, Vaughn investigated the theft of an Occamy hatchling and discovered that a bewitched sixth-year had been used to conceal a missing egg, leaving him to suspect Voldemort’s involvement.

• Hermione showed Harry and Ron the announcement that Beauxbatons and Castelobruxo had joined Vaughn’s international Potions exchange program, and described its significance for magical schools worldwide.
• Harry and Ron saw Professor Rosier take food to Vaughn, who had returned to Hogwarts after the pure-blood families began turning against one another.
• Isabella visited Vaughn in the practical-class small world and brought him breakfast while he spoke with an Occamy about the stolen hatchling.
• Vaughn questioned Isabella about who had entered the small world and pointed out that she had only searched the second-years, not the sixth-year volunteers.
• Vaughn examined the Occamy’s memories and realized that a sixth-year had been controlled by a notebook and that the real target had been one of the Occamy’s eggs.
• Vaughn recognized the notebook as connected to Tom and wondered why Voldemort knew so much about Occamy habits.

Fleur Delacour resented being assigned to lead Beauxbatons’ Potions exchange with Hogwarts because she blamed Vaughn Weasley for overshadowing her. Madame Maxime explained that international cooperation was becoming necessary and demonstrated how Vaughn’s new spell could make the Magic Extraction Method usable by wizards without exceptional Potions talent.

• Vaughn collected fragments of Anna the Occamy’s eggshell and wondered why Tom had stolen an egg.
• Fleur left her dormitory and learned that Madame Maxime was showing Dumbledore and Madame Silva around Beauxbatons.
• Fleur joined the visitors and bristled when Dumbledore praised Vaughn Weasley’s charm and Madame Maxime later confirmed that Fleur would lead the exchange team.
• Fleur told Madame Maxime she did not want to go to Hogwarts, and Maxime explained that the Potions exchange would prepare schools for wider international cooperation.
• Madame Maxime showed Fleur Vaughn’s paper and cast his unfinished spell, extracting visible properties from several materials.

Fleur Delacour learned from Madame Maxime that Vaughan Weasley’s magical methods and political maneuvers might be part of a deliberate, far-reaching plan. As the Potions Exchange Program gained another school but little attention, Vaughn investigated an Occamy egg at Hogwarts and joined the castle’s Halloween preparations, where Ginny showed how confidently she had settled in.

• Madame Maxime explained to Fleur that Vaughan’s published spell-development methods relied on an unfamiliar system, and Fleur agreed to study him while remaining cautious.
• Madame Maxime suggested Vaughan had deliberately waited for tensions between wizards and werewolves to peak before arresting John Mir and releasing a list that sowed distrust among wizarding families.
• Fudge visited Durmstrang to avoid the scandal surrounding the list, and Karkaroff signed the Potions Exchange Program contract, though Halloween news eclipsed the announcement.
• Vaughn searched ancient wizards’ journals for clues about why a student had tried to steal an Occamy egg, finding obscure rituals buried among the journal’s rambling entries and enchanted arguments.
• Vaughn saw Hogwarts being decorated for Halloween, and Ginny tried to frighten him before showing her lively, confident side among the younger Gryffindors.

Vaughn suspected that the Halloween feast would leave Hogwarts vulnerable, so he urged Ginny to keep Luna close and later confronted Snape about keeping Harry away from danger. Snape accused Vaughn and Dumbledore of neglecting the castle’s threats, while Harry, Ron, and Hermione remained stuck in Snape’s office dispute and prepared for Nearly Headless Nick’s party.

• Vaughn realized Halloween would leave much of Hogwarts empty and urged Ginny to invite Luna along while exploring the castle, since Luna could sense nearby malice.
• A fifth-year student told Vaughn that Peeves had dumped Snape’s potion ingredients on Harry, Ron, and Hermione, and Hermione later explained that Snape had kept Harry in his office all night over the false theft accusation.
• Vaughn brought Snape breakfast and deduced that Snape had arranged the incident to keep Harry away from danger, but Snape angrily challenged Vaughn’s and Dumbledore’s failure to investigate strange events in the castle.
• Harry and Ron argued with Hermione about Snape’s motives and their plan to attend Nearly Headless Nick’s deathday party, while Hermione brought them breakfast and scolded them for staying up all night.
• As a storm darkened the sky, Gryffindors gathered in the common room for Halloween, and Fred and George sold tickets to a film screening while Harry and Ron regretted agreeing to attend the ghost party.

Harry, Ron, and Hermione attended Nearly Headless Nick’s freezing deathday party, where Peeves’s disrupted threats led Hermione to suspect the diary was behind a deadly conspiracy. After Harry and Ron fell asleep, Hermione left Gryffindor Tower and summoned Fruit Tea.

• Harry, Ron, and Hermione went to Nearly Headless Nick’s deathday party in the Slytherin dungeons and warmed themselves with chocolate Hermione brought from Vaughn.
• Peeves enraged a ghost by claiming Hermione mocked him, so Harry provoked the Bloody Baron by saying Peeves had insulted him and loved the Grey Lady.
• Peeves threatened the trio before an unseen force sealed his mouth, and the Bloody Baron pursued him as the ghost party dissolved into gossip.
• Hermione reasoned that the diary had bewitched Peeves and Colin Creevey and forced Peeves into a contract concealing a deadly conspiracy.
• Harry and Ron returned to Gryffindor Tower and fell asleep, while Hermione cast a Disillusionment Charm, left the tower, and summoned Fruit Tea.

Vaughn revealed to Hermione that Harry’s lost diary was a Horcrux and explained his and Dumbledore’s plans to investigate it, while withholding the truth from Harry for now. After sending Hermione back to Gryffindor Tower, Vaughn reviewed his plans for practical lessons and recognized that the magical world’s limited technology was holding back his ideas.

• Hermione followed Fruit Tea to Snape’s office and overheard Vaughn confront Snape about his conflicting feelings toward Harry and tell him to learn to control his emotions before joining the Savior Protection Plan.
• Vaughn took the frozen Peeves from Snape’s office, confused him, and sent him wandering; he then found Hermione hiding nearby and told her about Voldemort, Horcruxes, and fate.
• Vaughn explained that Harry’s lost diary was a Horcrux and that he and Dumbledore were watching it to learn what it intended to do; he warned Hermione not to tell Harry what she had learned.
• Vaughn escorted Hermione back to Gryffindor Tower, then returned to the Slytherin Dungeon and considered why the diary had not acted during Halloween.
• Vaughn reviewed his practical Defense Against the Dark Arts plans and concluded that his ideas depended on technology the magical world did not yet have.

Vaughn moved up his plans to perform the Ether-Wandering Ritual while Hogwarts students celebrated Halloween and prepared for Quidditch. Gryffindor lost to Hufflepuff after Cedric caught the Snitch, and Wood, Harry, and the twins admitted that their reluctance to use Vaughn’s tactics had contributed to the defeat.

• Vaughn decided to prioritize preparing for the Ether-Wandering Ritual and learn more alchemy so he could guide Fred and George’s work.
• Harry and Ron learned that Gryffindor would play Hufflepuff in the season opener, and Ron encouraged Harry to take advantage of Vaughn’s absence from Quidditch.
• Hermione agreed to watch Harry train, and Wood led Harry and Ron through practice ahead of the match.
• Cedric caught the Golden Snitch in heavy rain, giving Hufflepuff a 250–230 victory over Gryffindor after Hufflepuff’s Chasers held Harry back.
• McGonagall challenged the dejected Gryffindor team to review its defeat, and Wood admitted that he had underestimated Hufflepuff and resisted using Vaughn’s tactics.
• Harry and the twins acknowledged their own reluctance to use Vaughn’s strategy, while the twins blamed Vaughn for making them run an errand to Hogsmeade the day before the match.

After McGonagall learned that Vaughn was preparing an Ether Voyage, she hurried to find him, while he used Reputation Points to advance his alchemy and discovered a new way to perceive the gateway to Aether. Vaughn prepared to enter by using a potion, but the chapter ended before he began the voyage.

• The twins joked about Vaughn’s plans, prompting McGonagall to realize he was preparing an Ether Voyage and demand that they take her to him.
• Vaughn examined his progress and spent 53 Reputation Points to raise his alchemy from Level 0 to Level 2.
• Vaughn’s Memory Archive and Personality Armaments processed the surge of alchemical knowledge, giving him a new perspective on the world and letting him see the gateway to Aether in his ritual pattern.
• Vaughn interpreted the ritual notes as requiring a potion rather than magic to enter Aether, and took a vial of silver-gray liquid from his satchel.

Vaughn drank Draught of Living Death to enter the Aether, but found himself in a vast dreamlike ocean instead. After witnessing blue figures perish beneath an immense giant’s gaze, he was pulled away and returned to the familiar Aether as his thoughts began to fragment.

• Vaughn drank Draught of Living Death and entered the Aether while Professor McGonagall hurried to the auxiliary tower with Fred and George.
• Vaughn found himself in a boundless azure ocean and used magic and a Consciousness Protection Charm to explore beneath its surface.
• Vaughn followed a blue phantom through the deep sea and watched it disintegrate when amber twilight appeared.
• The twilight revealed countless blue figures dying as a colossal giant with blazing eyes cried out, shattering Vaughn’s Personality Armament and cracking his protective charm.
• The charm’s flames turned Vaughn’s mind-body black and carried him away from the ocean and giant, returning him to the normal Aether as his thoughts began splitting apart.

Vaughn escaped the Aether but suffered an injury to his mind-body, and Dumbledore returned to Hogwarts to check on him. As Dumbledore described negotiations with China’s magical community, Vaughn argued that he had misunderstood who was resisting cooperation and revealed that the Qi Refiner People’s Committee had demands from the Muggle regime.

• Vaughn escaped the Aether by reaching his mental anchor and crashed onto the classroom floor, where McGonagall and the Weasley twins found him.
• McGonagall sent Fred and George to fetch Madam Pomfrey, then brought Vaughn to the hospital wing as she investigated what had happened to him.
• Vaughn considered the damage to his mind-body and recalled the giant, the darkness, and the translucent figures he had encountered in the Aether.
• Dumbledore returned from China, reassured McGonagall that Vaughn would recover, and asked to examine him, but Vaughn refused.
• Dumbledore explained that China’s Central Academy of Qi Refining was divided over reopening to international cooperation, and Vaughn corrected his account.
• Vaughn told Dumbledore that the Qi Refiner People’s Committee was likely the greatest obstacle to cooperation because it had demands from the Muggle regime.

Vaughn told Dumbledore about encountering a colossal being in the Aether, and Dumbledore identified it as Death, a god created through stories and mysticism. He revealed that ancient alchemists had also created the Golden Soul as a god for the universe, then began explaining the theories that led to its creation.

• Vaughn advised Dumbledore to use the Five Great Dao to learn what the Muggles wanted, and Dumbledore agreed to continue communicating with them.
• After McGonagall brought Vaughn food, Dumbledore asked what he had encountered in the Aether, and Vaughn described falling into a giant's dream.
• Dumbledore identified the giant as Death and explained that Nicolas Flamel had helped create it through the story of the three Peverell brothers and the influence of mysticism.
• Dumbledore revealed that Nicolas had used the giant's flesh and blood to make the Philosopher's Stone and had asked him to prevent the creation of new gods.
• Dumbledore explained that ancient alchemists had created the Cosmic Spirit, or Golden Soul, as a god for the universe, and asked Vaughn about the Ten Source Qualities theory.

Dumbledore explained to Vaughn how legendary alchemists may have altered the Aether while attempting to create gods, and confirmed that Death’s twilight light marked legendary wizards. Meanwhile, Hermione overheard that Vaughn had been injured in the Aether and went to find him as he endured nightmares and pain in the hospital wing.

• Dumbledore told Vaughn that sixteen legendary alchemists vanished after attempting to create lesser gods, and that their experiment may have changed how the Aether responded to thoughts.
• Dumbledore explained that the Aether’s responses included emotions and projections of souls, and that darkness might be one of the paths associated with the Ten Essences.
• Vaughn asked whether the twilight light in the Aether was Death, and Dumbledore confirmed it marked legendary wizards before their deaths.
• Hermione overheard Dumbledore and Professor McGonagall discussing Vaughn’s injury and their plan to keep it quiet, then left her books behind and hurried away.
• Professor McGonagall criticized Dumbledore for letting Vaughn enter the Aether alone, while Dumbledore insisted that alchemy could reach magic’s true essence.
• Vaughn woke from another nightmare in the hospital wing and returned to his Mindscape as pain and memories of the giant and twilight light continued to trouble him.

Vaughn studied Nicolas Flamel’s account of divine contamination and speculated about the Grim Reaper, the Peverell brothers, and legendary wizards while recovering from his mental injury. Hermione stayed by him in the hospital wing, and Harry and Ron learned that Vaughn was injured but were told to keep it secret.

• Vaughn read Nicolas Flamel’s book and concluded that contact with Death might have exposed him to mind-altering contamination, which could be restrained by casting the Patronus Charm.
• Vaughn speculated that Nicolas Flamel had suppressed the god-creation plan and wondered whether the Grim Reaper had been created to kill legendary wizards.
• Hermione rushed into the hospital wing and embraced Vaughn, then stayed with him as he explained that her presence helped him recover and fell asleep again.
• Harry and Ron searched for Hermione, and Nearly Headless Nick led them to the hospital wing, where they learned Vaughn was injured.
• McGonagall let Harry and Ron glimpse Hermione beside Vaughn, then ordered them to keep his injury secret.
• Hermione left to get chocolate and hot cocoa for Vaughn, while Ron later sighed sadly about him in Gryffindor Tower.

Harry and Ron accidentally spread news of Vaughn’s serious injury after Seamus overheard them, and Snape punished them for breaking their promise to McGonagall. At Hagrid’s, Vaughn practiced the Patronus Charm with Dumbledore and suspected that his weakened Personality Armament might have let someone interfere; he expected his recovery to take about two weeks.

• Harry explained to Ron that Vaughn’s injured mind-body might mean his soul had been harmed, while Scabbers listened and reacted strangely.
• After Harry and Ron fell asleep, Scabbers struggled against a white mist in its mind, then slipped from its cage and went to Seamus’s bed.
• Seamus repeated the news of Vaughn’s injury as firsthand information from Harry and Ron, and the story spread through all four houses.
• Snape accused Harry and Ron of breaking their promise to McGonagall, took ten points from Gryffindor, and threw them out of Potions class.
• Harry and Ron went to Hagrid’s, where they saw Vaughn practicing magic with Dumbledore; Hermione scolded them for letting the news spread.
• Vaughn told Dumbledore he suspected his weakened Personality Armament had enabled the leak and estimated that his recovery would take about two weeks.

Vaughn recovered at Hagrid’s Hut while Dumbledore traveled to Laojun Mountain with Beauxbatons and Chinese refiners. Madame Maxime learned that China sheltered formidable legendary wizards and ended the chapter watching Dumbledore reunite with one of them.

• Dumbledore told Vaughn he would be away for two weeks and left him to recover at Hagrid’s Hut.
• Harry and Ron remained guilt-ridden as rumors spread about Vaughn, until Hermione told them in early December that Vaughn’s nightmares had stopped.
• Dumbledore led Madame Maxime, Fleur Delacour, and Chinese refiners to Laojun Mountain to visit his old friend.
• An interpreter told Madame Maxime that four Celestial Masters and fifteen Perfected Ones cultivated in seclusion on the mountain, shocking her with China’s magical strength.
• Madame Maxime urged Fleur to seize the potions exchange opportunity and stay close to Vaughn, then watched Dumbledore greet a legendary wizard at the mountaintop shrine.

Dumbledore, Madame Maxime, and Pheobe met Master Li, whose anger over past persecution and Dumbledore’s failure to help had fueled his distrust of the international wizarding community. After learning that Hogwarts second-year Vaughn Weasley had advised Dumbledore on negotiations with China, Master Li agreed to continue talks, leaving Pheobe and Madame Maxime eager to understand Vaughn’s influence.

• Madame Maxime and Pheobe met Master Li, who challenged Dumbledore to reveal who had recognized China’s intentions and prompted him to take Muggles seriously.
• Master Li used magic to silence and drain the color from the room as he accused Dumbledore and Mahoutokoro of complicity in past massacres and abandonment of the Far East.
• Master Li explained that he had obstructed renewed international ties because he distrusted Dumbledore, but he was prepared to let negotiations proceed while he lived.
• Dumbledore revealed that Hogwarts second-year Vaughn Weasley had advised him, including on proposals for smuggling Muggle equipment into China through wizarding channels.
• Master Li accepted the situation and sent his granddaughter Yan Li to guide Dumbledore, Madame Maxime, and Pheobe to their guest rooms.
• Yan Li told Pheobe that Vaughn had done what Master Li had always wanted to do, while Dumbledore told Madame Maxime that Vaughn understood China’s history, disasters, ideas, and needs.

Harry and Ron visited Vaughn at Hagrid’s hut, where he was recovering and experimenting on potion-making. Vaughn’s attempt to develop a pharmaceutical base led him to consider potions as active, life-like systems, a new direction prompted by his vision of the “giant” in the aether.

• Harry, Ron, and Hermione found Vaughn brewing an experiment beside Hagrid and learned that his nightmares had stopped affecting his daily life.
• Vaughn explained that he was developing a pharmaceutical base and discussed why wizarding medicines took different forms from Muggle medicines.
• Vaughn combined a cloudy substance from his cauldron with Flobberworm slime while examining how the mixture changed.
• Hermione connected Vaughn’s ideas to potions behaving like miniature life forms, and Vaughn described how extracted properties vanished when separated from their ingredients and carrier.
• Vaughn reflected that potions and their properties might be active systems, a perspective he had begun to consider after seeing the “giant” in the aether.
