Chapter Summaries

Dumbledore followed Master Li into the mountains to witness Chinese magic that could capture clouds and weave them into a chariot. A Qi Practitioner awakened Mount Lao Jun’s dragon vein, and the resulting clouds gathered in the dawn as the kind needed for the chariot.

• Dumbledore admired Master Li’s knowledge of his protective Buoyancy Charm variation and learned that Vaughn had invented it.
• Master Li led Dumbledore through the storm to watch a Qi Practitioner struggle to ring a Dragon-Calling Bell.
• The bell’s chimes shook the mountain range and triggered an avalanche, while Master Li explained that the mountains’ earth veins were called Loong.
• The Qi Practitioner rang the bell again, awakening the dragon vein and sweeping aside the wind and snow.
• Clouds poured from a distant peak and glowed red in the sunrise, and Master Li identified them as the clouds they would capture to make a chariot.

Dumbledore recorded his observations of the Qi Practitioners and sent Vaughn a letter warning him that Eastern magic was far more powerful and complicated than expected. At Hogwarts, Vaughn spent the Christmas holiday studying and visiting Hagrid while Ron avoided him out of embarrassment over having no presents to give; Fawkes arrived with Dumbledore’s letter.

• Dumbledore described how Qi Practitioners used golden threads to gather clouds summoned through the Loong and wrote down his observations for Vaughn.
• Dumbledore handed his letter to Little Li, who let it pass without inspection because it was addressed to Vaughn Weasley.
• Vaughn spent the first five days of the holiday walking Guoguo Tea, reading Ravenclaw manuscripts, and visiting Hagrid, while Harry and Ron kept their distance.
• Ron felt ashamed that Percy, Fred, and George had spent his money on unsold prank toys instead of Christmas candy, leaving him without return gifts for his friends.
• Harry tried to reassure Ron, and the two watched Fawkes fly toward Hagrid’s Hut carrying Dumbledore’s letter.

Harry and Ron visited Vaughn after seeing Fawkes arrive with Dumbledore’s letter, which warned of China’s magical capabilities and the dangers of controlling weather. Ron’s attempt to ask when Dumbledore would return ended with Vaughn and Guoguo Tea teasing him about his unpaid Christmas gift.

• Harry and Ron saw Fawkes fly to Vaughn’s pavilion carrying a letter, and Ron agreed to go there with Harry.
• Hermione read Dumbledore’s letter about China’s isolation, its magical weaknesses, and the terrifying possibilities of controlling rain and thunderstorm clouds.
• Vaughn read Dumbledore’s warning that the clouds used for cloud carriages might retain the destructive properties of real clouds, and he reflected on Dumbledore’s fears about China and the Statute of Secrecy.
• Harry asked Vaughn when Dumbledore would return because he wanted to consult him, and Ron stressed that only Dumbledore could help.
• Vaughn reminded Ron about his unpaid Christmas gift, while Guoguo Tea looked down on him, and Ron angrily promised to repay Vaughn ten times over next year.

Vaughn prepared to develop the Universal Functional Group before visiting magical schools arrived, and invited Hermione to assist him after she deduced that his idea involved Fluxweed. The next morning, Hermione eagerly headed to the experiment with two breakfasts, while the research was still ahead.

• Ron admitted to Harry that Vaughn had deliberately provoked him into promising tenfold compensation, and regretted making the promise.
• Hermione recognized that Vaughn’s teasing came from concern for Ron, but Vaughn insisted Ron’s oath meant he would collect the promised gifts.
• At Hagrid’s Hut, Vaughn told Hermione he needed to develop the Universal Functional Group before China and other schools arrived in ten days.
• Hermione connected Vaughn’s research to Fluxweed’s transformation Traits, and Vaughn invited her to join as an assistant who would mainly observe and think.
• Hermione spent the night excitedly preparing to work with Vaughn, then woke early and picked up two breakfasts before heading to the experiment.

Hermione joined Vaughn in his laboratory to study his Universal Functional Group research and learned that he envisioned microscopic active tools rather than a universally adaptable substance. Vaughn demonstrated his approach by teaching her to use his Multi-Spectrum Vision Charm, then unleashed a maximized darkness spell on Araclaid, leaving Hermione hearing strange sounds in the absolute darkness.

• Hermione brought breakfast to Vaughn's laboratory, where she found Araclaid weakened and trembling after volunteering for Vaughn's experiments.
• Vaughn explained to Hermione that his Universal Functional Group would use active tools, and Hermione recognized his design as nanorobots that could interact with cells and Potions Traits.
• Hermione studied Vaughn's Notebook and quickly absorbed its data before asking him about the microscopic devices he had designed.
• Vaughn activated a Magical Ritual and helped Hermione adapt to his Multi-Spectrum Vision Charm so she could participate in the experiment.
• Vaughn released Araclaid from his bottle and cast Nox Maxima, plunging the room into absolute darkness as Hermione heard the Acromantula scream and other strange sounds.

Vaughn showed Hermione how the Multi-Spectrum Vision Charm revealed Acromantula cells and the magic-channel proteins that carried magic factors into them. He then taught her how protein folding shaped a protein’s possible functions, leaving her with the enormous number of potential conformations a short peptide chain could take.

• Vaughn used a rotating polyhedron and changing light waves to expose Araclaid’s body, while Hermione saw an Acromantula anatomy diagram at microscopic resolution.
• Vaughn guided Hermione through the cell membrane, where she observed ordinary channel proteins transporting nutrients and waste.
• Hermione watched a dark tubular channel capture and carry material as Vaughn identified it as a magic-channel protein that transported basic magic factors into Magical Creatures’ cells.
• Hermione asked whether the proteins could carry potion Traits, and Vaughn explained that magical proteins and magic factors were more complex than simple transport.
• Vaughn sent Hermione a memory showing an unfolded protein and taught her about amino acid units, peptide chains, and how folding determined protein functions.
• Vaughn explained that a chain of thirty amino acid units could have roughly ten to the thirtieth power possible conformations.

Vaughn taught Hermione how he planned to combine magic and molecular biology to develop magical channel proteins, and she began assisting him with the research. At breakfast, Harry and Ron learned that Hermione was studying molecular biology and that Neville hoped to join Vaughn’s Potion Exchange Event, but Ron mocked Neville’s ambition.

• Hermione realized that magic such as Felix Felicis could help search the vast possibilities of protein folding, and Vaughn explained how probability and Transfiguration fit into his design.
• Vaughn outlined how Fluxweed could help reveal magical protein structures and support protein production, while Hermione recorded his ideas and asked questions.
• On the ninth day of Christmas break, Ron pointed out Hermione’s large stack of Muggle biology books, and Harry admitted he did not know the terms she was studying.
• Neville told Harry and Ron that Hermione was teaching herself molecular biology and that she was Vaughn’s credited essay assistant in Extraordinary Potions.
• Neville said he had subscribed to the journal to study for Vaughn’s Potion Exchange Event, and Ron mocked him and suggested he was doing it because of Vaughn.

Neville defended Vaughn’s research after Harry and Ron mocked his study habits, then left them to read Vaughn’s essay in Extraordinary Potions. The article described how Vaughn’s Universal Functional Group could transform potion-making, and Harry and Ron began to hope he would succeed.

• Neville angrily told Harry and Ron that Vaughn’s research could simplify potion-making, then left the Great Hall after rebuking them for mocking him.
• Harry admitted that he and Ron had been wrong to laugh at Neville and suggested apologizing, while Ron refused.
• Harry and Ron struggled to understand Vaughn’s technical essay and turned to Hermione’s overview and editor Damocles Belby’s commentary.
• Belby explained that Vaughn’s proposed Universal Functional Group could make brewing as simple as casting spells and allow wizards to observe and replenish magical power.
• Harry and Ron recognized how much easier potion-making could become, and Ron said he believed Vaughn would succeed.

Harry and Ron discussed the opposition to Vaughn’s Universal Functional Group and worried that Snape might turn against him. At Vaughn’s laboratory, Snape witnessed the protein robots delivering a potion into an Acromantula and challenged Vaughn about the unseen machines, while concealing a deeper reason for his opposition.

• Harry and Ron read Belby’s article about industrializing Potions and discussed the backlash Vaughn might face from Potioneers.
• Ron suggested that Snape could oppose Vaughn because the Universal Functional Group challenged the Potions craft, and Harry decided they should watch Snape and tell Hermione if he seemed troubled.
• Harry and Ron searched Hogwarts for Snape and Vaughn’s laboratory, then apologized to Neville at lunch.
• Vaughn and Hermione demonstrated the Universal Functional Group in a laboratory while Snape watched through the Multi-Spectrum Vision Charm.
• Snape questioned how the protein robots could be verified when he had seen only black outlines carrying the phosphorescent potion.
• Vaughn explained that the robots’ three-dimensional structure remained a black box and described how he had created a stable conformation using Araclaid’s Magic Protein, a Protein Transformation Potion, and Felix Felicis.

Vaughn defended the Universal Functional Group against Snape’s objections, while its ability to let Muggles use potions raised fears about changing the magical world. Vaughn revealed that Dumbledore feared him because he judged people and creatures by their usefulness to his plans, not their origins.

• Snape challenged the Universal Functional Group’s production costs, but Vaughn and Hermione explained how misfolded protein robots could reproduce their effects without continued use of rare ingredients.
• Snape realized the protein robots might let Muggles use potions by bypassing the need for Magic Power, and accused Vaughn of deliberately pursuing that possibility.
• Vaughn acknowledged that he understood the danger of his work and that Dumbledore understood it too, while Snape recalled Vaughn’s longstanding interest in why some people could use magic.
• Vaughn asked why Dumbledore would distrust him if he were simply trying to help Muggles, and Snape began to reconsider his assumptions.
• Vaughn summoned the listless Araclaid and said Dumbledore feared him because he judged beings by their usefulness to his plans rather than their backgrounds.

Vaughn explained to Snape that the Statute of Secrecy was an outdated system that suppressed the Wizarding world's productive forces and made political change inevitable. After Snape left shaken, Vaughn and Hermione continued developing their protein-based Potions method and planned to ask Snape for more Felix Felicis.

• Vaughn told Snape that magic was the Wizarding world's productive force and argued that the Statute of Secrecy obstructed social change and innovation.
• Vaughn asked Hermione to imagine Goyle or Crabbe as her superior, then explained that he included Muggles in his new Potions system to unleash magic's potential.
• Snape left in turmoil after Vaughn described Voldemort as a catalyst for reform rather than a powerful leader, and Hermione asked whether Vaughn had shaken him too badly.
• Vaughn and Hermione resumed researching the Universal Functional Group and identified protein aggregation as a problem that shortened the potion's shelf life.
• Vaughn proposed using a Vanishing Spell variant to break protein bonds and creating molecular chaperones to prevent the protein robots from aggregating.
• When Hermione pointed out they were nearly out of Felix Felicis, Vaughn said he would ask Snape for more.

Vaughn persuaded Snape to help him obtain Felix Felicis by showing him the Resurrection Stone, while Hermione wondered whether the potion would arrive in time for their research. The Daily Prophet then attacked Vaughn’s new potion-making method, leaving Harry and others worried that it could expose the Wizarding world to Muggles.

• Vaughn left Snape’s office after arranging for Snape to help him buy Felix Felicis, and Snape sat holding a sketch of the Resurrection Stone.
• Hermione read that a delegation from the Central Alchemy Academy would arrive in England in five days, while the Daily Prophet made Vaughn’s potion-making method its front-page story.
• Harry and Ron read an article condemning Vaughn’s work and warning that Magic Protein could lead Muggles to discover magic and start a war.
• Dean argued that Vaughn could make his ideas a reality, while Fred and George tried to dismiss the article’s warnings with jokes.

Harry tried to understand Vaughn’s Magic Protein research for himself, while Ron worried that backlash against Vaughn might endanger the Weasley family. The holiday ended with Hogwarts’s professors gathering in the Great Hall, as Harry and Hermione remained buried in their studies.

• After reading conflicting arguments about Vaughn’s research, Harry decided to investigate it himself and asked Hermione for books.
• Harry spent the holiday studying, while Ron followed the fierce public debate over Magic Protein and the threats directed at Vaughn.
• Fred and George warned Ron that people might target the Weasley family, and Harry said he had found someone to restrain them.
• Ron heard that Draco Malfoy had ordered Goyle and Crabbe to beat Marcus Flint and several Ravenclaw students, then reached the Great Hall with Harry on the evening before the holiday ended.
• Ron saw that all the professors had returned to the professors’ table, including Professor Binns, who chatted with Nearly Headless Nick.

Dumbledore returned to Hogwarts and announced that the Quidditch Cup would be canceled because the school was hosting an international Potions exchange. Afterward, he told Vaughn that the Central Alchemy Academy delegation had reached London and was pursuing a wider diplomatic mission.

• Dumbledore's return calmed the students and professors, and Vaughn joined the Slytherin table as Draco reported that Flint and several Ravenclaws had been involved in the plot against the Weasley family.
• Dumbledore addressed the school, declined to state his position on Vaughn's Magic Protein, and announced that the second-half Hogwarts Quidditch Cup was canceled.
• Dumbledore explained that Hogwarts would host the first International Magic Academy Potions Exchange Event, and Harry left while Vaughn stayed behind to speak with him.
• Vaughn asked about the Central Alchemy Academy delegation, and Dumbledore said they were in London after visiting several countries to restore old international relations.

Vaughn agreed to meet China’s delegation after Dumbledore revealed their unusual interest in him and speculated that their decades-long secret operation might have involved Aether and the gods. The meeting would be arranged as a formal conference, and Vaughn left Dumbledore wondering whether he intended to recruit Li Nanyu into his research group.

• Dumbledore told Vaughn that China had requested a meeting with him and seemed to value him more than the negotiations themselves.
• Vaughn and Dumbledore discussed China’s secret operation, which had run from the 1960s until a little over ten years ago and might have been connected to Aether and its gods.
• Dumbledore explained that the Chinese delegation had bypassed Fudge after his visit to the Magic Institute angered them, and that Barty Crouch would likely manage the formal conference.
• Vaughn agreed to meet the delegation and considered using his recent essay as a pretext for the conference.
• When Dumbledore said Li Nanyu was interested in Vaughn’s research, Vaughn suggested recruiting him into his research group.

Dumbledore tried to limit Vaughn’s influence over the Potion Exchange Event, but the Hogwarts professors’ loyalties and Sybill Trelawney’s alarming prediction disrupted his plan. Vaughn learned of the meeting and prepared for his upcoming meeting with the Chinese delegation while explaining why he and Dumbledore let their rivalry stay limited to minor setbacks.

• Dumbledore convened the Hogwarts professors and proposed diverting students who lacked Potion talent into other subjects, but Rosier, Kettleburn, and Snape opposed the plan.
• McGonagall recognized that the professors’ academic ties and loyalties aligned them with Vaughn, while Filius and Pomona stayed silent.
• Sybill Trelawney predicted that foreign witches would bring chaos and conspiracy to Hogwarts, then appeared not to remember her outburst.
• Dumbledore used the interruption to end the tense meeting by claiming the professors supported Vaughn’s work.
• Rosier told Vaughn about Dumbledore’s plan and urged him to retaliate, but Vaughn said their minor rivalries helped preserve their cooperation.
• Vaughn explained that he was preparing a new recipe for his formal meeting with the Chinese, though some problems remained unresolved.

Isabella urged Vaughn to help finish the Trial Grounds renovations before visiting school delegations could judge the practical class reform. Meanwhile, Harry and Ron failed to catch an Augurey, and after Hermione explained a better approach, they wondered whether the Trial Grounds had become stale.

• Isabella warned Vaughn that Dumbledore could use the visiting delegations and the unfinished Trial Grounds to undermine the practical class reform, so she demanded that Vaughn inspect the renovations with her.
• Harry and Ron failed to catch an Augurey after wind exposed their underground approach, and the bird escaped with its nest after dropping its feathers and droppings on them.
• Harry and Ron returned muddy to their cabin, where Hermione explained how they could trade for Fairy eggs and use them to obtain Augurey feathers.
• Hermione's advice left Harry and Ron impressed, and they complained that the practical class had become repetitive after months of exploring the Trial Grounds.

Vaughn and Isabella discussed the practical class losing student interest and Isabella’s desire to make its trials more realistic, while Vaughn insisted that safety controls were essential. As they returned to the laboratory, Vaughn suspected Isabella’s anxiety came from a fear she had not revealed.

• Ron worried to Harry that students were losing interest in the practical class and that it might fall apart.
• Isabella told Vaughn that the Trial Grounds had become repetitive and difficult to maintain, while Vaughn considered the class a tool for expanding his influence and future plans.
• Isabella explained that the practical class could prepare young wizards for real dangers, including Voldemort’s possible return, and proposed abandoning the mission system’s safety restraints.
• Vaughn rejected making the practical class entirely real because young wizards and Magical Creatures could be seriously harmed by uncontrolled magic.
• Isabella asked Vaughn to keep students interested until she left her post, and Vaughn later told Guoguo Tea that he sensed she was afraid of something.

The Daily Prophet reported that a Chinese delegation wizard had exposed magic to thousands of Muggles in London, while Harry and Ron visited Hagrid as he helped prepare the Quidditch Pitch for visiting delegations. Vaughn and Dumbledore arrived at the Leaky Cauldron, where Tom explained that the suspicious patrons were information brokers seeking details about the Chinese wizard.

• A Chinese delegation wizard summoned a Cloud Carriage in Westminster, forcing the Department of Magical Accidents and Catastrophes to cover up the exposure with fog and memory loss.
• Harry, Ron, Dean, and Seamus discussed the incident and whether it might cause trouble for Vaughn.
• Harry and Ron found Hagrid rebuilding the Quidditch Pitch as a residential and activity area for the visiting delegations, and Harry tried to help him move logs.
• Harry flew over the pitch and spotted a green flash from the Headmaster's Office, then Vaughn arrived through the Floo Network to meet Dumbledore in Diagon Alley.
• At the Leaky Cauldron, Vaughn teased Dumbledore about the hidden patrons, and Tom said they were information brokers investigating the Chinese wizard's London incident.

Vaughn, Dumbledore, and Old Barty Crouch discussed the Chinese wizard’s Magic Exposure Incident and the stalled meeting with the Chinese delegation. Crouch proposed using Vaughn’s recent research to involve the English Branch as a mediator, explaining that the branch’s Irish officials had their own interests and growing tensions with the International Confederation of Wizards.

• Vaughn told Dumbledore that WAC had found suspicious details about the Chinese wizard’s Magic Exposure Incident, including an unscheduled Auror presence and the Ministry’s rapid response.
• Dumbledore and Vaughn met Old Barty Crouch, who explained that the Confederation’s English Branch had eased its obstruction of their meeting with the Chinese after the incident heightened tensions.
• Vaughn described his improved Universal Functional Group, and Old Crouch suggested using the research as grounds to have an English Branch official mediate and witness the meeting.
• Old Crouch explained that the English Branch’s officials came from Ireland and argued that their interests had diverged from the Confederation’s efforts to control its branches.
