Chapter Summaries

After Hugo revealed that an unknown attacker had bypassed his unusual magical defenses, Sean suspected the attacker was a Temporary Vessel connected to Sloth and the Returners. Unable to confirm Hugo’s connection to Gluttony or learn the Returners’ plans, Sean left the hospital and visited his prison inside the ring, where Thomas taunted him.

• Hugo demonstrated that his fat stored magic power that could resist spells, but the attacker had knocked him unconscious without consuming it.
• Hugo recalled feeling as if the magic power in his body had lost its vitality, leading Sean to suspect a Temporary Vessel with power from Sin Sloth, possibly Leon Schneider.
• Sean questioned whether the attacker had targeted Hugo because of Gluttony, but Hugo felt no change, leaving Sean unsure whether he was a Sin or merely being tested.
• Sean went to Dumbledore’s office, but the Gargoyle told him the Headmaster was absent, so Sean entered the Room of Requirement and climbed into his ring.
• Sean visited the cave prison, passed Gormlaith Gaunt, a captured Returner, petrified Death Eaters, and Fenrir, then confronted Thomas, who offered to reveal the Returners’ plan.

Sean used Thomas’s reactions and the Returners’ recent actions to infer how Thomas’s divided soul and Sloth magic worked, then told him the Returners had abandoned him. The chapter ended with Sean offering to let Thomas feel the new Sloth vessel’s power.

• Sean provoked Thomas about his ties to the Returners, and Thomas threatened to torture Sean’s family and friends.
• Sean restrained himself from killing Thomas and concluded that Thomas was eager to die because death would let a backup soul preserve his memories.
• Sean guessed that Thomas had split his soul among multiple bodies and used them to share pain and resist the Imperius Curse.
• Thomas’s reactions strengthened Sean’s suspicion that the Returners had a backup soul ready to receive information if the three captive bodies died.
• Sean explained that the Returners had created another vessel for Sloth magic and revealed that someone had already attacked him with it.

Sean confirmed that Thomas’s body combined Sloth’s magic with an Obscurus and used doubts about his abandonment and Horcrux to undermine him. He then led Golden Dawn toward the grounds, where Krum was preparing to fly, intending to provoke the Durmstrang students and investigate them.

• Sean deduced from Thomas’s reaction that the Returners had fused Sloth’s magic with an Obscurus in a vessel, and Thomas denied the accusation.
• Sean suggested that the Returners had abandoned Thomas and might leave his Horcrux useless, unsettling him before Sean left.
• Sean reflected that Grindelwald’s return was approaching and resolved to find the vessel hidden among the Triwizard Champions to avenge Stephanie.
• News spread that Krum planned to fly on Hogwarts grounds, and Ron’s excitement drew mockery from Fred and George.
• Sean and Golden Dawn set out to observe the Durmstrang students, and Sean urged the group to talk with them as Krum inspected his broom.

Sean confronted Reinhardt Nott and Krum at the Quidditch pitch, probing their reactions while they traded insults. After Reinhardt mocked Hermione and her Oppugno spell, Sean cast it on a flock of conjured birds, ending the chapter as thunder roared.

• Sean arrived at the Quidditch pitch with Hogwarts students and challenged Reinhardt Nott, while Krum tried to discourage a confrontation.
• Sean questioned Reinhardt about why he disliked him, then mocked him as Krum attempted to intervene.
• Reinhardt insulted Muggle-born students and targeted Hermione, but Sean defended her and praised her abilities.
• Reinhardt mocked Hermione’s Oppugno spell, and Sean conjured yellow birds with Avis before casting Oppugno.

Sean confronted the Durmstrang students after Reinhardt Nott insulted Hermione and his friends, using four Thunderbirds to overwhelm Reinhardt. The clash ended with Krum offering an apology just as Karkaroff arrived and demanded to know what was happening.

• Sean summoned four Thunderbirds with Oppugno and ordered them to attack Reinhardt, leaving him badly injured and unconscious.
• Reinhardt fired a spell at Sean, but Sean's flock of summoned birds swallowed it before the Thunderbirds attacked again.
• Krum shielded Reinhardt from another Thunderbird dive with a defensive barrier, then confronted Sean about starting a conflict between the schools.
• Sean challenged the Durmstrang students and searched for signs of magic linked to the Obscurus or Sin, but none dared face him.
• Krum apologized on Reinhardt's behalf to Hermione and Sean's friends, but Karkaroff arrived before Sean answered.

Sean defended himself after his Thunderbirds injured Reinhardt, and he claimed the creatures had appeared through a mutated Summoning Charm. Daisy’s tearful account of Reinhardt’s past bullying shifted Snape’s support toward Sean, while Karkaroff left threatening to pursue the matter.

• Karkaroff accused Sean of using Thunderbirds to attack Krum and Reinhardt, while McGonagall and Snape demanded an explanation.
• Sean dismissed the Thunderbirds and claimed his Avis Summoning Charm had accidentally produced them, and Krum confirmed that account.
• Sean admitted that he had injured Reinhardt with Oppugno after Reinhardt insulted him and his friends, and McGonagall assigned Sean castle-cleaning duty and banned him from the Quidditch pitch.
• Daisy tearfully described Reinhardt’s insults and bullying, prompting Snape to threaten Karkaroff over Durmstrang’s conduct.
• Karkaroff left with the Durmstrang students after vowing not to let the matter go, and Daisy resumed her pitiful act when Snape looked at her.

Sean’s response to Reinhardt’s attack turned Durmstrang into a target of widespread hostility, while he and Malfoy pursued separate investigations. A message from Young Grindelwald announced that Valley and Lake Island would open on June 24, the same day as the Four-School Tournament’s final event, leaving Sean alarmed by the timing.

• Rumors and photographs of the Quidditch-pitch incident spread through Hogwarts, and students across the schools increasingly shunned Durmstrang after Reinhardt Nott’s insult and Karkaroff’s defense of him.
• Hogwarts students tried to reach Reinhardt in the Hospital Wing, but Karkaroff’s guards stopped them after a professor watching Reinhardt had been poisoned.
• Sean met Malfoy, who reported that more than half of Slytherin had joined the Society of Glory and that Reinhardt Nott and Theodore Nott appeared to share only a surname.
• Sean told Malfoy to investigate the Nott connection by the end of term and reflected that he needed to protect the upcoming Grindelwald fusion and find the lurking Sin Vessel.
• Sean received Lupin’s note that Young Grindelwald’s messenger had announced Valley and Lake Island would open on June 24, 1996.
• Sean realized June 24 was also the date of the Four-School Tournament’s final event.

Sean suspected the Returners had arranged the Four-School Tournament’s final task to coincide with the date Grindelwald began time travel, and he searched Dumbledore’s office for answers. The chapter ended with a portrait revealing that Dumbledore was walking into death, leaving Sean demanding to know why.

• Sean connected the tournament’s June 24 final task with Grindelwald’s time-travel date and worried that the Returners had learned something from Trelawney’s incomplete prophecy.
• Sean returned to Hogwarts and entered Dumbledore’s office after the Gargoyle gave him Dumbledore’s prepared response.
• Sean searched the office for a clue while arguing with Phineas Black and the other former headmasters in their portraits.
• Armando Dippet revealed that Dumbledore was walking into death, and Sean demanded an explanation.

Sean confronted the former Hogwarts headmasters about Dumbledore’s expected death and deduced that Dumbledore had hidden part of the prophecy, possibly involving a sacrifice to avert the coming catastrophe. The portraits could not reveal more, but Sean then found Dumbledore waiting in the Room of Requirement, ready to explain things properly.

• Sean persuaded the portraits that Dumbledore carried too much alone and urged them to help him avoid his death.
• Dilys Derwent explained that the portraits were bound to follow the current headmaster’s will, and the silent portraits confirmed Sean’s suspicion that Dumbledore was doomed to die.
• Sean reasoned that Dumbledore had concealed part of the prophecy, possibly a passage tying his death to the resolution of the Sins and other threats.
• Sean left the Headmaster’s Office and entered the Room of Requirement, where he found Dumbledore waiting.
• Dumbledore asked Sean to give him time and said he was ready to explain some things properly.

Sean confronted Dumbledore about his secrecy and challenged him to reconsider equality, human nature, and his pride, turning their conversation into an unexpected lesson for the headmaster. Dumbledore then began to explain that he had withheld information about Sin because it affected Sean.

• Sean told Dumbledore he was hurt that the headmasters had guarded information from him and questioned whether Dumbledore was hiding part of the prophecy.
• Dumbledore asked whether wizards and Muggles could live in equality, and Sean used his family’s expensive piano to argue that fairness did not mean equality.
• Sean argued that people were born with different abilities and that those with power should provide others with equal opportunities to develop.
• Sean challenged Dumbledore’s understanding of human nature, saying his kindness and pride had kept him from seeing people clearly.
• Sean described Helga Hufflepuff as the proudest Founder because she believed she could educate students rejected by the other houses.
• Dumbledore admitted that Sean had educated him, then said some withheld matters concerned Sin and affected Sean.

Dumbledore told Sean that Sin was an ancient, accumulated bloodline curse whose full awakening could be vastly more powerful than the force seen in Paris, and warned that revealing too much might hasten it. Sean interpreted Dumbledore’s hints as permission to investigate a Sin Vessel at Durmstrang, while Strong Hartman was suddenly knocked unconscious in Hogwarts.

• Dumbledore explained that Sin had accumulated power through a bloodline over a thousand years and that its Paris manifestation had been only a fraction of its true strength.
• Dumbledore said he had concealed part of the prophecy because an Unbreakable Vow and Sin’s nature prevented him from revealing everything, and he urged Sean to study the nature of Sin’s magic.
• Sean concluded that Dumbledore’s hints pointed to a Sin Vessel at Durmstrang and decided to stir up trouble there, believing Dumbledore would keep higher-level powers from interfering.
• After more than half a month of ostracism, Strong Hartman hurried through Hogwarts Castle and fainted when his vision suddenly went black.

Sean interrogated Strong Hartman to learn about Durmstrang, its students, and the school’s guarded areas. After uncovering signs of suspicious activity involving Ront Lloyd and sealed-off locations, Sean altered Strong Hartman’s memories and left him believing Hogwarts students had beaten him.

• Strong Hartman woke tied to a chair and answered Sean’s questions about his background and life at Durmstrang.
• Sean learned that Durmstrang had sealed unused dormitories after alleged Dark Arts experiments and that the school had unusually few students.
• Strong Hartman described Ront Lloyd as a withdrawn second-year who had severely cursed classmates after they tricked him, leading Sean to suspect a connection to Sloth.
• Strong Hartman explained that Durmstrang’s ship had protective magic, an expanded interior, and a forbidden area that Professor Karkaroff kept students away from.
• Sean used Memory Weaving on Strong Hartman, beat him, and left him believing Hogwarts students had attacked him.

Strong Hartman returned to the Durmstrang ship and fell under suspicion after a screening revealed a gap in his memories, while Sean Wallerup used him as a distraction. As the Black Hood waited for Strong to trigger a planned disturbance, Sean infiltrated the ship’s restricted lower level disguised as Isamar Trelawney and sent his scout into a secret room.

• Strong Hartman boarded the ship with injuries, underwent a lengthy magical screening, and learned that Isamar Trelawney had also been beaten.
• The screening wizard reported Strong’s missing memories to the Black Hood, who ordered him watched and planned to turn Strong’s scheme against him.
• Strong reflected on his unhappy time at Durmstrang, then followed woven memories onto the deck while the Black Hood’s agents monitored him.
• The Black Hood mistook Strong’s movements for preparations to set a fire and told his agents to remain alert while keeping the ship’s Magic Barrier active.
• Sean Wallerup, disguised as Isamar Trelawney with Polyjuice Potion, slipped past the guard into the restricted area and sent his scout through a ring into a secret room.

Sean used Edmund Grub to investigate the Durmstrang ship and discovered six young wizards imprisoned in magical cages. Fearing the captives could be moved if the enemy was alerted, Sean returned to gather trusted Hogwarts professors and the Wizarding Charitable Association’s recruitment records.

• Sean learned from Edmund Grub that six young wizards in Durmstrang uniforms were shackled and imprisoned in secret chambers beneath the ship.
• Sean suspected the conspicuous objects beside the captives were Portkeys and decided that alerting the enemy could let them move the children.
• Sean returned Isamar Trelawney to the ship, made a weak Detection Spell probe, and left; the Black Hood ordered a staged inspection to lure him aboard.
• Sean asked Edmund to summon trusted Hogwarts professors to their offices, then traveled to Newmontgard and the Wizarding Charitable Association.
• Sean asked Lupin to gather the association members who had helped Hogwarts with recruitment and obtain the enrollment forms and details they had handled.

Sean discovered that Durmstrang had illegally imprisoned dozens of young wizards, and he and the Hogwarts professors struggled to plan a rescue that would protect both the students aboard the school’s ship and those still inside the castle. He proposed gathering their allies to attack Durmstrang Castle once the ship returned, and claimed he had ideas for getting in and finding enough people.

• Sean reviewed the recruitment figures and realized that twenty to thirty Durmstrang students were unaccounted for.
• Sean told Lupin about the missing students, and they agreed to alert trusted allies while preparing for a possible confrontation with Durmstrang.
• Sean returned to Hogwarts and informed McGonagall and the other professors that Durmstrang was imprisoning young wizards and that the Returners might be involved.
• The professors considered ways to block Portkeys and protect students at both the ship and the castle, but they could not agree on a workable plan.
• Sean proposed waiting until the ship returned to Durmstrang Castle and then rescuing all the students in a single assault.
• When Flitwick warned that an attack would require overwhelming numbers, Sean said he had ideas for entering Durmstrang and securing manpower.

Sean and the professors planned to rescue the imprisoned young wizards from Durmstrang after the Triwizard Cup, while Snape equipped Sean with four rare potions to help him survive. After Daisy warned that the children might be connected to Obscurus, Sean suspected the Returners were deliberately cultivating it and decided to investigate before they acted.

• Sean persuaded the professors to prepare for a coordinated assault on Durmstrang after the Triwizard Cup, while he continued probing without alerting the enemy.
• Snape gave Sean Trace Remover, Boiling Poison, Magic Power Enhancer, and Hardening Potion, explaining their effects and warning him to survive.
• Hermione condemned Durmstrang after Sean told her and the others about the imprisoned young wizards, but agreed they must not alert the enemy.
• Daisy raised the possibility of Obscurus, prompting Sean to connect the children's oppression to the conditions that could create Obscurials.
• Sean warned that a rescue attempt could trigger a group of rampaging Obscurus and decided to learn how the Returners cultivated and controlled them.

Reinhardt Nott returned to Durmstrang after recovering and confronted Leon Schneider about the school’s secrets and the attack on Daisy Potter. Leon revealed that he was an Obscurial, forced Reinhardt to accept a magical safeguard, and offered him a chance to join a hidden group after completing a test.

• Karkaroff welcomed Reinhardt Nott back at a party aboard the Durmstrang ship, while Reinhardt remained consumed by his humiliation at Sean Wallop’s hands.
• Reinhardt confronted Leon Schneider, suggesting that Sean suspected Leon of attacking Daisy Potter and questioning Leon’s ties to Karkaroff and the ship’s restricted area.
• Leon admitted he was an Obscurial and offered Reinhardt a choice between joining the group or being replaced and killed.
• Leon bound Reinhardt with black particles and threatened him before ordering him to lower his Occlumency.
• Leon implanted a magical safeguard in Reinhardt’s mind, and Reinhardt agreed to complete a test for a chance to join the group.

Sean investigated the Returners’ spellwork on missing children and considered whether their trap targeted the Pride within him, while Hermione worried that their real aim might be something else. After Malfoy reported secret contact between Theodore Nott and Reinhardt Nott, with Reinhardt carrying the Nott family crest, Sean decided to approach Theodore himself.

• Lupin reported that the Returners had Obliviated or Imperiused the families of missing children, and Sean ordered his people recalled and carefully checked.
• Sean saw Reinhardt Nott glaring at him in the Great Hall and heard Hermione warn that the Returners’ plans might conceal a different purpose.
• Sean considered the possibility that the Returners’ trap targeted Pride and thought about entering the Realm of Illusion through its open entrance.
• Malfoy told Sean that Theodore Nott and Reinhardt Nott had secretly met, and that Reinhardt had taken the Nott family crest.
• Sean told Malfoy to continue observing Theodore and decided to find an opportunity to meet him.

Sean suspected Malfoy’s interest in Theodore Nott might be part of a trap, so he followed Theodore after the boy sent a letter asking his father about the Nott family’s ancient origins. Sean’s Thunderbirds intercepted the owl, but the operation ended with the Aero-Wing Bird returning it unconscious and covered in saliva.

• Theodore Nott wrote to his father asking whether the Nott family had lost relatives beyond their reach and where the family’s bloodline originated.
• Theodore sent the letter with his specially trained British Long-Eared Owl after checking that Draco Malfoy was not nearby.
• Sean followed Theodore under a Disillusionment Charm and sent his Thunderbirds to intercept the owl.
• Sean waited at the edge of the Forbidden Forest as the Thunderbirds returned with the Aero-Wing Bird.
• The Aero-Wing Bird spat out Theodore’s unconscious, saliva-covered owl, leaving Sean stunned.

After intercepting Theodore Nott’s letter about the Nott family’s origins, Sean suspected Reinhardt Nott might be connected to the Returners and chose to investigate him directly. He overheard Reinhardt tell Theodore that their bloodline belonged to one of the Eight Great Families and contained a power tied to Sin.

• Sean read Theodore Nott’s letter asking whether the English Notts were the last surviving branch, which made him reconsider Reinhardt’s connection to the Returners.
• Sean decided to target Reinhardt first, enlisted ghosts to monitor the Durmstrang students, and concealed himself in a castle wall.
• Helena reported a disguised Durmstrang student avoiding others, and Sean used the Marauder’s Map to track Theodore Nott to a hidden meeting place.
• Sean sent Naja to spy through a crack as Theodore met Reinhardt, who was disguised as another student.
• Reinhardt told Theodore that their bloodlines belonged to the Eight Great Families and held a special power, then asked whether Theodore had heard of Sin.
