Chapter Summaries

Vaughn watched Harry resist the diary’s pull and began questioning whether fate was an intelligent force, but the diary was stolen while he and Dumbledore left the underground chamber. By the end, Vaughn and Snape both suspected fate had manipulated events, while the thief remained unknown somewhere in Hogwarts.

• Vaughn considered provoking fate’s backlash by using the Personality Armament to remove Harry from the basement, but Harry chose to leave the diary behind on his own.

• Ron spread news of the professors’ fight, while Vaughn realized someone had stolen the diary from Snape’s office during the previous night.
• Snape suspected Ron, Harry, and then Vaughn, but ruled out Ron and Harry because neither carried the potion scent he had placed on the diary.
• Vaughn searched his memories and tried to locate the diary, but its signal wandered throughout Hogwarts, leaving him unsure who had stolen it.

Vaughn learned from Dumbledore that Peeves had stolen the diary, while Dumbledore urged him not to interfere with fate. Dumbledore then traveled to Nurmengard, where two watchers discussed Grindelwald and the upheaval caused by Vaughn Weasley and WAC.

• Dumbledore revealed that Peeves had stolen the diary and asked Vaughn to stop pursuing it, then redirected their conversation to the training grounds and Vaughn's potions paper.
• Dumbledore left Hogwarts with Fawkes and arrived at Nurmengard, where Polo and Leonid watched the castle from the snowy mountainside.
• Leonid told Polo that Dumbledore had come to visit Grindelwald, and they discussed the werewolf march and the political threat WAC posed to pure-blood interests.

Polo feared the changes surrounding Grindelwald’s return, Wilkinson, and Vaughn Weasley, but Leonid persuaded him to consider sending his son to Vaughn’s school exchange programme. At Nurmengard, Dumbledore explained to Grindelwald why he had supported Vaughn and confessed his suspicion that Vaughn’s apparent concern for others concealed a deep indifference to the world.

• Dumbledore revealed that Vaughn’s exchange programme included plans to influence Hogwarts’s curriculum, while Grindelwald questioned Dumbledore’s leniency toward him.
• Dumbledore admitted that his intimidation of Tom Riddle as a child might have helped shape Tom’s obsession with power, and said he did not want to repeat that mistake with Vaughn.
• Dumbledore told Grindelwald he had considered leaving Vaughn stranded in North America but chose to help him, partly because Vaughn had ideals and was decisive like Grindelwald.
• Dumbledore said he believed Vaughn cared little about the fate of wizards, Muggles, or the world, despite showing affection for his family, Hermione Granger, and Ravenclaw’s students.

Dumbledore explained to Grindelwald that Vaughn planned to challenge the International Statute of Secrecy by raising the status of house-elves and werewolves, then asked for Grindelwald’s help as his life neared its end. The story then shifted to Harry, who struggled with anxiety over a missing notebook and Hermione’s silence before receiving his second-year timetable.

• Dumbledore told Grindelwald that Vaughn sought to unravel the laws of magic and oppose the magical world’s stagnation, not through violence but by exploiting a loophole in the International Statute of Secrecy.

Harry let Colin Creevey photograph him, while Ron’s attempt to reconnect with Hermione failed when she revealed she knew about his and Harry’s secret investigation of the practical class. Professor Isabella Rosier introduced an aggressive, hands-on Defence Against the Dark Arts course and led the students through a protected doorway, where Harry was shoved into the dark and emerged in a moonlit wilderness.

• Harry agreed to pose for Colin Creevey’s photograph, and Hermione took the picture after stopping Ron from mishandling the camera.

Harry, Hermione, and the other students faced giant wolves during Vaughn’s first practical lesson, while Vaughn and Isabella watched the creatures herd them through a shifting maze. As Vaughn discussed the wolves’ origins and resistance to magic, he argued that humans were distinguished from beasts by their free hands.

• Giant wolves poured from the forest and attacked the students, and Hermione rallied Harry, Ron, and the others with spells.
• Hermione realized the wolves were driving the students toward the forest rather than simply trying to kill them, but one wolf dragged Neville away screaming.
• Vaughn reshaped the small world into a maze that separated the student groups, while Isabella worried that the wolves might injure them or infect them with lycanthropy.
• Vaughn explained that the giant wolves were a distinct species born to werewolf parents transformed under the full moon, and that they were no longer affected by lycanthropy.
• Malfoy, Goyle, and Crabbe attacked their pursuing wolves with dark spells, but the magic failed to stop them and the wolves carried the three into the forest.
• Vaughn asked what separated humans from magical creatures and concluded that humans had hands free to use.

Vaughn explained why Dire Wolves were not the werewolf-virus creator’s final creations, while Harry, Ron, and Hermione fled through a magically altered forest during a practical lesson. As the trio faced a Devil’s Snare, Sebastian, Jack, and Freya discussed their duty to guide and protect the students and Vaughn’s plan to establish a Hogwarts Werewolf Class.

• Vaughn told Isabella that Dire Wolves had lost the ability to spread the werewolf virus and could still help him in other ways.

• Sebastian, Jack, and Freya discussed whether to keep driving the students onward, with Freya reminding Jack that Vaughn had asked them to protect the young wizards as well as test them.
• Jack recalled Barnard’s account of werewolf children becoming Obscurials and Vaughn’s plan to establish a Werewolf Class at Hogwarts.

During the practical lesson, Dire Wolves rescued injured students even as Vaughn revealed to Isabella that he intended the Werewolf Class proposal to provoke hostility and make werewolves see him as their sole savior. The exercise ended with the young wizards transported back to Hogwarts, shaken and battered.

• Aurora Sinistra visited Isabella in tears, acknowledging that she understood the effort to draw attention to neglected subjects like Astronomy.

Vaughn’s paper on werewolf descendants and the Dire Wolves provoked backlash against his practical classes, but international support for his Potions exchange weakened Fudge’s position. Dumbledore arranged for Vaughn to meet Nicolas Flamel after Vaughn completed his first Aether Journey, while concealing Flamel’s real purpose.

• At a staff gathering, Professor Sinistra and Professor McGonagall supported Vaughn’s practical classes and criticized the governors’ prejudice after his paper mentioned the Dire Wolves.

• Vaughn suspected Dumbledore was hiding Flamel’s true intentions, while Dumbledore said Fudge was suffering from the international pressure.

Vaughn and Dumbledore negotiated over the Ministry’s practical-class inquiry, the international potions exchange, and the Chamber of Secrets, while Harry, Ron, and Hermione explored the revised practical class. Harry suspected their search for a Runespoor egg might involve a dangerous illusion and stopped his companions after noticing something on the map.

• Dumbledore explained that Fudge’s political position had weakened and agreed that Fudge could participate in the international potions exchange; Vaughn warned that they should stay alert during the month-long postponement of the practical-class hearing.
• Vaughn challenged Dumbledore’s handling of the Werewolf Class proposal, then revealed that the Chamber of Secrets entrance was in the abandoned girls’ Washroom on the second floor and that Parseltongue was needed to open it.
• Dumbledore demanded further information about Horcruxes, and Vaughn pointed out that Harry could speak Parseltongue; Vaughn later left the headmaster’s office thinking about how to keep the werewolf factions and their opponents divided.
• Oliver Wood intensified Gryffindor’s Quidditch training after hearing that Vaughn might leave the Slytherin team, while Hogwarts’ practical classes expanded into three-hour sessions with tasks, points, and blind-box prizes.
• Harry, Ron, and Hermione entered the dark forest to search for a Runespoor egg, using a quest scroll that displayed their progress and a map as Ron argued that Vaughn had made the forest deliberately frightening.
• Harry recalled reports of students encountering a Runespoor and wondered whether they had entered its dreamlike fantasies; while studying the map, he suddenly told Ron and Hermione to be quiet.

Harry, Hermione, and Ron encountered Colin Creevey in the jungle while investigating an approaching presence. Meanwhile, Vaughn attended a Hogwarts Board of Governors meeting where governors challenged his practical classes and Direwolf research, leaving the board divided as the Ministry backed him.

• A Ministry representative announced that Minister Fudge accepted Vaughn's Direwolf findings and that the Ministry supported his request.

Vaughn confronted the Hogwarts governors over the Dire Wolf research and offered to let Seba bite him to prove Dire Wolves could not spread lycanthropy. After Seba returned to the tribe shaken by the meeting, Harry began considering the latest practical class’s failure and its consequences.

• Lucius Malfoy watched Vaughn address the representatives of the Wesley, Pickford, and Charlton families while Fudge joined Vaughn’s side.
• Vaughn silenced Alecto with a display of powerful magic, summoned Fawkes and Seba, and offered his arm for Seba to bite as proof of the Dire Wolf’s safety.
• Seba recalled its past mistreatment and realized the governors’ challenge could endanger Vaughn and obstruct werewolf rights, but it bit him after he reassured it.
• Fawkes took Seba back to the Forbidden Forest, where Seba met the centaur Albedo and invited him to hear its concerns and share them with Firenze and Magorian.
• Harry reflected that his team had failed to finish the practical-class mission because the map’s arrow markings revealed enemy locations as well as runic snake eggs.

Harry and Ron learned that the Hogwarts Board of Governors was questioning Vaughn over practical classes and his plan to educate werewolf children, while Neville earned praise for driving off Mooncalves. Vaughn appeared at dinner with an injured left arm, but he told Professor McGonagall that his research would be proven at the Board’s meeting on the full moon.

After Harry realized Colin Creevey had once carried the notebook’s strange presence, practical classes continued and Professor Rosier demonstrated how students could have defeated the Kappa.

• Professor Flitwick urged Professor McGonagall to make the Dueling Club a school-wide class, and she left unsure whether it would overwhelm other subjects.
• Professor Flitwick revealed that news of Vaughn’s Board meeting had leaked and objected to the Governors forcing Vaughn to prove himself through self-harm.

• Harry watched Colin and found no trace of that presence, while Colin continued following him around Hogwarts with his camera.
• Professor Rosier showed the fourth-years two ways to defeat the Kappa after their class failed, and her rebuke about cucumbers became a popular catchphrase.

Harry told Ron and Hermione about the dangerous diary and his suspicions that it had influenced him, but his confession that he had hidden it from Vaughn drove Hermione away and strained his friendship with Ron. As Harry worried about the diary and their falling-out, Wood woke him before dawn and demanded that he attend Quidditch practice.

• Wood learned from Marcus Flint that Vaughn had left the Slytherin Quidditch team and celebrated by preparing even more intense training for Gryffindor.

• Harry told Ron and Hermione about the diary, Snape confiscating it, and his suspicion that Colin Creevey had encountered it; Ron and Hermione warned that it was likely a Dark Magic object containing a human soul.
• Harry and Ron rejected Hermione's suggestion to tell the professors, and Harry refused to tell Vaughn until they had dealt with the diary; when he admitted he had hidden it out of jealousy or fear, Hermione stormed out.
• Harry realized that his jealousy toward Vaughn might have been caused by the diary and resolved that he needed to improve his magical strength.
• Wood woke Harry in the predawn darkness and insisted he come to Quidditch practice after he had stayed awake for thirty hours planning the team's tactics.

The chapter left Harry heading toward Hagrid’s hut and Vaughn focused on his stalled research into the second-edition Wolfsbane Potion.

• Harry found Colin Creevey waiting outside the changing room and spent four hours training with the Gryffindor team while Creevey watched and cheered.
• Harry tried to learn from Fred and George whether Vaughn’s Dueling Club would open, but the twins dodged his questions and distracted him with a staged argument.
• Harry remembered how Ron and Hermione had once stayed beside him after practice, then turned away from the castle to visit Hagrid’s hut.
• Harry’s guilt over hiding the notebook surged as he neared Hagrid’s hut, triggering a warning from the Personality Armament that Vaughn sensed in the Room of Requirement.
• Vaughn chose not to investigate Harry immediately and returned to his work on the second-edition Wolfsbane Potion, whose development had been stymied by the werewolf virus’s magically protected, reusable capsid.
