Chapter Summaries

Dumbledore followed Master Li to watch Chinese cultivators capture clouds and weave them into a carriage. He witnessed a True Lord awaken Laojun Mountain’s dragon vein with the Loong-Calling Bell, causing the mountains to shake and clouds to surge from a peak as dawn broke.

• Dumbledore showed Master Li his modified Bubble-Head Charm, and Master Li learned that Vaughn had invented it.
• Master Li led Dumbledore through the storm to watch a qi cultivator shake the Loong-Calling Bell and awaken Laojun Mountain’s dragon vein.
• Master Li explained that a loong’s awakening summoned clouds, while Dumbledore watched the surrounding mountain ridges shudder.
• The True Lord rang the bell again, and vapor poured from a distant peak, spreading clouds across the mountains in the red dawn.
• Master Li pointed out the clouds they would capture to make a carriage.

Dumbledore wrote Vaughn a detailed account of the qi cultivators and the earth-vein Loong he had witnessed in China, while Vaughn spent the Christmas break at Hogwarts. The chapter ended with Fawkes bringing Dumbledore’s letter to Vaughn near Hagrid’s Hut as Harry and Ron sat nearby.

• Dumbledore described how cultivators awakened the earth-vein Loong and used its clouds, then wrote Vaughn about the power he had seen in China.
• Little Li allowed Dumbledore to send the letter to Vaughn without inspecting it.
• Vaughn spent the break walking by the Black Lake, reading in Ravenclaw’s hidden library, and visiting the gazebo he had built with Hagrid.
• The twins failed to wake the giant squid and lost Ron’s money after their prank-toy business failed, leaving Ron embarrassed about not having gifts to return.
• Harry tried to persuade Ron to sell his presents, but Ron refused to part with them.
• Fawkes arrived carrying Dumbledore’s thick letter as Harry and Ron watched from near Hagrid’s Hut.

Harry and Ron visited Vaughn after seeing Fawkes arrive with a letter from Dumbledore, whose warnings described China’s magical capabilities and the danger of controlling real storm clouds. Vaughn reflected on Dumbledore’s fears about the changing wizarding world, then teased Ron over his missing Christmas return gift as Harry tried to ask when Dumbledore would return.

Vaughn planned to begin developing the Universal Functional Group using Fluxweed, and invited Hermione to assist under strict limits. Hermione eagerly accepted and prepared to join him the next morning, while Vaughn’s experiment was set to begin.

• Ron admitted to Harry that Vaughn had provoked him into promising to give him Ireland team signed gear ten times over.
• Hermione realized Vaughn was teasing Ron out of affection, then learned that Vaughn intended to start his experiment the next day.
• Vaughn explained that he planned to develop the Universal Functional Group before the visiting exchange delegations arrived and hinted that Fluxweed was central to his idea.
• Hermione connected Vaughn’s research to Fluxweed, and Vaughn invited her to assist by observing, thinking, and doing little.
• Hermione spent the night excitedly preparing to join Vaughn’s research and woke before dawn to head to the Great Hall, where she got two breakfasts.

Hermione joined Vaughn’s research and learned that his universal functional group concept relied on proactive microscopic tools rather than changing substances themselves. Vaughn demonstrated his Multispectral Vision Charm and began a frightening experiment on Araclaid, leaving Hermione in absolute darkness with the Acromantula’s cries and strange bodily sounds around her.

• Hermione brought breakfast to Vaughn’s laboratory and found Araclaid weak and terrified in a jar, while Vaughn said the Acromantula had volunteered for the research.
• Vaughn explained that his universal functional group would use tools resembling nanobots to interact with cells, and Hermione studied his dense notebook until she understood the proposal.
• Vaughn activated a magical ritual and used his Multispectral Vision Charm, guiding Hermione as she learned to interpret the world through ripples of light.
• Vaughn floated Araclaid into the air and cast a maximized Light-Extinguishing Charm, plunging the laboratory into absolute darkness as Hermione heard the Acromantula scream.

Vaughn showed Hermione how he used the Multispectral Vision Charm to observe Araclaid’s cells and identify magical channel proteins that transported magic into them. He then taught her how protein folding could create countless possible structures and functions, leaving the mechanism of magical protein synthesis unresolved.

• Vaughn used a turning polyhedron and intense light to expose Araclaid’s anatomy, while Hermione observed his cells through the Multispectral Vision Charm.
• Vaughn guided Hermione closer to the cell membrane, where she watched channel proteins transport nutrients and spotted a dark, moving channel.
• Vaughn identified the dark channel as a magical channel protein that carried fundamental factors of magic into magical creatures’ cells.
• Vaughn explained that magical proteins came in several kinds and that merely transporting them would not explain how magic was synthesized.
• Vaughn sent Hermione a memory of an unfolded protein and taught her about amino acid units, side chains, and protein folding.
• Vaughn explained that a protein with thirty amino acid units could fold into roughly ten to the thirtieth power possible conformations, each potentially producing a different function.

Vaughn explained to Hermione how magic could help him investigate and engineer magical proteins, and she eagerly followed his reasoning. At breakfast, Harry and Ron learned from Neville that Hermione had become Vaughn’s research assistant, while Neville declared that he intended to study Potions and join Vaughn’s exchange activities.

• Vaughn taught Hermione how Felix Felicis, Fluxweed, and Transfiguration could help him study magical channel proteins and develop his design.
• Hermione enthusiastically recorded Vaughn’s ideas, and he saw her as a fellow traveler who might help his research and future team.
• At breakfast, Ron pointed out Hermione’s pile of Muggle molecular biology books, and Harry admitted he did not recognize the terms she was studying.
• Neville told Harry and Ron that Hermione’s reading and work were described in the latest issue of Extraordinary Potions, where she was credited as Vaughn’s research assistant.
• Neville revealed that he had subscribed to the journal and planned to study Potions for Vaughn’s exchange activities, prompting Ron to mock his ambition.

Harry and Ron read Damocles Belby’s commentary on Vaughn Weasley’s research into a universal potion solvent and began to understand how it could transform potion-making. They left impressed by the possibility of simpler potion-brewing and continued reading about Vaughn’s research.

• Neville angrily defended Vaughn’s research and left Harry and Ron after criticizing them for mocking him.
• Harry admitted that he and Ron had been at fault and suggested they apologize to Neville, while Ron refused.
• Harry and Ron struggled to understand Vaughn’s technical paper, then turned to Hermione’s overview and Damocles Belby’s commentary.
• Belby explained that Vaughn’s proposed protein-based universal carrier could simplify potion-making and help reveal how magic could be replenished.
• Harry and Ron recognized how much easier potions could become, and Ron said he believed Vaughn would succeed.
• Harry and Ron continued reading as they realized Belby was already familiar with Vaughn’s theories and experiments.

Harry and Ron worried that potion-makers’ opposition to Vaughn’s Universal Radical could drive a wedge between Vaughn and Snape, and they searched Hogwarts for Snape. They found no sign of him until Snape appeared in Vaughn’s laboratory, where he challenged the claims about the Protein Robot after witnessing its effects.

• Harry and Ron read Damocles Belby’s article on the Universal Radical and discussed the potion-makers who opposed Vaughn.
• Ron suggested that Snape might resent Vaughn’s plan to transform Potions, and Harry decided they should watch Snape and warn Vaughn if necessary.
• Harry and Ron searched Hogwarts for Snape and Vaughn’s laboratory, then apologized to Neville at lunch.
• In Vaughn’s laboratory, Snape watched Vaughn and Hermione demonstrate how the Protein Robot delivered a fluorescent potion into an Acromantula’s cells.
• Snape questioned Vaughn’s account because he had seen only black silhouettes transporting the fluorescent markers, and Vaughn explained that the Protein Robot’s structure remained a black box.

Vaughn explained how the Universal Functional Group’s Protein Robots could spread through misfolding, prompting Snape to realize the system might let Muggles use potions. Snape challenged Vaughn’s motives, and Vaughn ended by saying he judged people and creatures by their usefulness and ability to realize his ideas, not by their origins.

• Vaughn and Hermione explained that Protein Robots could replicate their conformation through misfolding, while Snape acknowledged the ingenuity of the mechanism.
• Snape warned that the Protein Robots could make magical potions usable by Muggles, and Hermione recognized the likely consequence.

• Vaughn admitted that Dumbledore understood his intentions, leaving Snape to reconsider why Dumbledore feared him.
• Vaughn summoned Araclaid and told Snape that he judged Muggles, blood-status groups, wizards, and magical creatures by their usefulness to his plans.

Vaughn explained to Snape that the International Statute of Secrecy suppressed the wizarding world's productive forces and made social change inevitable, leaving Snape shaken by Vaughn's view of Voldemort as a catalyst rather than a great leader. Vaughn and Hermione then continued researching Protein Robots, and he planned to ask Snape for more Felix Felicis.

• Vaughn told Snape that the International Statute of Secrecy was backward and argued that magic's productive forces would inevitably overturn the wizarding world's existing social order.

• Dumbledore said Barty Crouch Sr. would arrange the meeting after the Chinese delegation cut off contact with Fudge over his visit to Mahoutokoro.
• Dumbledore suggested Vaughn's recent paper as a reason for the meeting, noting that Li Nanyu was interested in his research.
• Vaughn asked how interested Li Nanyu was, then revealed he was considering recruiting him into his research group.

Dumbledore tried to limit Vaughn’s influence over the international Potions exchange, but Hogwarts’s professors opposed him and Sybill Trelawney’s vision gave him a graceful retreat. Vaughn dismissed Rosier’s calls to challenge Dumbledore and continued preparing a new formula for his upcoming meeting with the Chinese delegation.

• Dumbledore proposed diverting visiting students into other subjects to reduce the scale and influence of Vaughn’s Potions exchange, but Rosier, Kettleburn, and Snape objected.
• Trelawney interrupted the meeting with a vision of foreign wizards bringing chaos and bloodshed, easing the tension and allowing Dumbledore to end the meeting without pressing his proposal.

• Harry and Ron tried to approach an Augurey's nest through a tunnel, but the wind alerted the bird, which flew off with its nest and left them covered in mud.
• Harry and Ron returned to their cabin, where Hermione cleaned them with a gust of wind and explained how to trade Mooncalf dung for fairy eggs to obtain Augurey feathers.
• Hermione said she had learned the plan by studying Newt Scamander's book and inferring what to do from the creatures' habitats and diets.
• After cleaning off and resting, Ron said the Practical Class was becoming boring because they had already explored much of the Trial Grounds.

Vaughn and Isabella discussed the Practical Class’s fading appeal and the danger of making its lessons more realistic. Isabella left the conversation determined to keep the class going, while Vaughn suspected she was hiding the cause of her urgency.

• Ron told Harry that students were losing interest in the Practical Class and Hermione was treating its missions as chores.
• Isabella explained that the Trial Grounds’ scripted missions were becoming repetitive and costly to maintain, putting student support and the class’s future at risk.
• Vaughn considered the Practical Class a way to build influence and leverage, while Isabella argued that young wizards needed preparation for dangers such as Voldemort and the Death Eaters.
• Isabella proposed making the Practical Class completely real, but Vaughn rejected abandoning its safety controls because students’ and fantastic beasts’ magic could cause serious injuries.
• Isabella admitted that last year’s events might have frightened her, then asked Vaughn to keep students enthusiastic until she left Hogwarts.
• Afterward, Vaughn told Fruit Tea that Isabella seemed afraid of something and might be hiding the reason for her anxiety.

A Chinese visitor’s accidental magic in Westminster caused a major exposure incident, while Harry and Ron discussed its fallout and visited Hagrid as he prepared the Quidditch Pitch for visiting school delegations.
