Chapter Summaries

Sean and Hermione attended classes, where Daisy won Felix Felicis in Potions and Sean earned Transfiguration points, before Lockhart’s disastrous lessons left Sean smelling of garlic. They went to Hagrid’s hut after he invited them, but found him missing and saw a black shadow emerge from the Forbidden Forest.

• Sean explained that he and Hermione could practice making Cough Potion because he had seen Moon Dew Flowers and Snape’s lesson notes while helping Hagrid.
• Daisy brewed a perfect Cough Potion and received Felix Felicis from Snape, while Sean earned ten Ravenclaw points for his Transfiguration button.
• Lockhart released Cornish Pixies in Defense Against the Dark Arts, then made Sean play a vampire in a staged scene from his book.
• Sean and Hermione went to Hagrid’s hut after receiving his invitation, but found it empty and noticed his boots and crossbow were missing.
• As Sean and Hermione prepared to leave, a black shadow shot out from the edge of the Forbidden Forest.

Sean treated Fang’s wound and waited for help, suspecting that Hagrid’s disappearance and Fang’s arrival were part of a trap. When Hermione returned with the professors and a badly injured Dave, they revealed that an ancient creature had attacked Hogwarts and asked Sean to help save Dave in the Forbidden Forest.

• Fang arrived at Hagrid’s Hut badly wounded, and Sean healed him before placing him in his ring.
• Sean waited for reinforcements, reasoning that Hagrid might be in danger and that Fang could be bait.
• Hermione returned with Professor McGonagall and Professor Flitwick, carrying Dave’s limp Egg Sac after a flash of light struck her near the covered bridge.
• The professors explained that an ancient power had compromised Hogwarts’s protections and that an awakened Magical Creature in the Forbidden Forest might be able to save Dave.
• Sean agreed to help and followed the professors toward the Forbidden Forest, then calmly raised his wand as his grief vanished.

Sean resisted an illusion that tried to lure him into the Forbidden Forest, then discovered that Hagrid was being controlled by a Horned Serpent. After the serpent emerged from Hagrid’s body, Sean and Pudding attacked it.

• Sean recognized the scene with Hermione and the professors as an illusion and returned to Hagrid’s hut.
• Sean concluded that the illusionist could affect only one target at a time and waited by the hut while guarding himself with Naja.
• Hagrid emerged from the Forbidden Forest, and Sean suspected that a creature was controlling him.
• The being identified itself as a Horned Serpent and agreed to leave Hagrid’s body so it could speak with Sean.
• The Horned Serpent crawled out of Hagrid’s mouth, and Sean and Pudding immediately attacked it.

Sean confronted a ghostly Horned Serpent that had controlled Hagrid and learned it had awakened recently and sought help fulfilling a wish left by Isolt Sayre. The creature escaped toward the center of the Forbidden Forest before Professor McGonagall and Newt arrived to examine Hagrid.

• Sean's spell and Pudding's claws passed through the Horned Serpent, which vanished and left Hagrid in its control.
• Sean questioned the Horned Serpent, and it said it had awakened days earlier, did not know what it wanted, and believed Sean could help fulfill its master's wish.
• The Horned Serpent identified its master as Isolt Sayre and said it had lured Sean into the Forbidden Forest to use ancient power to communicate.
• After Dave warned Sean that the professors were coming, the Horned Serpent sensed their approach and invited Sean to meet it at the forest's center before vanishing again.
• Professor McGonagall and Newt arrived, and McGonagall examined Sean and Hagrid while Sean warned them the creature could turn invisible.

Sean returned safely from the Forbidden Forest after encountering a Ghostly Horned Serpent, and Newt suspected it might be connected to Isolt Sayre. Newt left to inform Dumbledore while Sean returned to the Common Room, where Hermione anxiously questioned him about what had happened.

• Sean told Professor McGonagall and Newt what had happened, and Newt wondered whether the Ghostly Horned Serpent could be connected to Isolt Sayre.
• Newt speculated that the serpent had chosen Sean because he shared Isolt’s closeness to nature, then escorted him back toward the castle.
• Newt returned Dave’s Egg Sac to Sean and asked him to correct Dave’s habit of threatening to eat his brain.
• Newt went to find Dumbledore, while Sean returned to the Common Room and reassured Hermione that he would explain what had happened.

After Daisy saw an image of a Horned Serpent, she remembered that a person with one coiled around him had cursed her, suggesting that her memories had been magically altered. Sean realized Daisy also had exceptionally high Magical Creature Affinity, and grew concerned about her planned meeting with Hagrid.

• Hermione brought Sean a book about the world’s ancient magic schools and identified Isolt Sayre as a founder of Ilvermorny.
• Sean told Daisy about the Horned Serpent and warned her to stay away from the Forbidden Forest.
• After seeing the creature’s likeness, Daisy panicked, embraced Sean, and remembered seeing a Horned Serpent beside the person who cursed her.
• Sean suspected that the image had triggered Daisy’s altered memories and learned she planned to meet Hagrid the next day.
• Sean asked Dave to assess Daisy’s scent and concluded that she shared his unusually high Magical Creature Affinity.

After Daisy was targeted by a Ghostly Horned Serpent, Sean considered whether she had been the true target of the letter and memory triggers, but he could not make sense of the clues. He waited for Dumbledore in the Headmaster’s Office, where Dumbledore finally returned from meeting with the Ministry of Magic.

• Sean comforted Daisy, asked Hermione to look after her, and hurried to tell a professor about the Ghostly Horned Serpent.
• Sean suspected the letter and the serpent might have been aimed at Daisy, and wondered whether the serpent opposed the person who had cursed her with the Blood Curse.
• Sean went to Dumbledore’s office, where the portraits of former headmasters argued about him, including Phineas Nigellus Black and Eupraxia Mole.
• Sean waited nearly an hour in the office before Dumbledore emerged from a burst of flame and apologized for keeping him waiting after his meeting with the Ministry of Magic.

Dumbledore told Sean that a stolen object from the Department of Mysteries could open a breach between the living world and the Realm of Illusion, allowing souls to return as ghosts. He suspected the thief planned to use those ghosts to fulfill a prophecy, possibly targeting Daisy, and began to reveal it to Sean.

• Dumbledore told Sean that the Ministry of Magic had lost an important object, which he believed was a key or needle.
• Dumbledore explained that the Realm of Illusion was another name for the Otherworld and that the stolen object could pierce the barrier separating it from the living world.
• Dumbledore revealed that several souls had escaped through the breach and returned as ghosts with powers, including the Ghostly Horned Serpent.
• Dumbledore warned that the escaped ghosts would pursue their wishes from life and that the thief planned to use others to accomplish his goal.
• Dumbledore said he believed the thief's goal involved a prophecy, and Sean pressed him to explain it.
• Dumbledore told Sean that perhaps it was time to reveal the prophecy.

Dumbledore took Sean into his memories with a Pensieve to show him the events surrounding a prophecy said to encompass an entire era. In the memory, a younger Dumbledore confronted Grindelwald and demanded to know where Cassandra Vablatsky was.

• Dumbledore explained that prophecies were uncertain insights and that people could become trapped by believing in them.
• Dumbledore drew a memory from his temple and invited Sean to enter the Pensieve with him.
• Sean and Dumbledore followed a younger Dumbledore through a village to Grindelwald's house.
• The younger Dumbledore confronted Grindelwald and demanded to know where Cassandra was.
• Grindelwald led Dumbledore toward a dungeon cell, claiming he had saved Cassandra Vablatsky's life.

Sean witnessed Cassandra Vablatsky deliver a prophecy about Sin’s return and a world-ending disaster, then heard Dumbledore explain the ancient catastrophe behind it. Dumbledore revealed that Sean was Pride, the first of the Seven Deadly Sins and the incarnation of Sin.

• Grindelwald and Dumbledore argued over his plans to found a new School of Magic while Cassandra Vablatsky remained unconscious.
• Vablatsky awoke in a trance and prophesied that Sin would return after a thousand years, led by Pride, bringing destruction unless the old age paid for its sins.
• Vablatsky collapsed after warning that everyone would die, and Sean returned from the memory to Dumbledore’s office.
• Dumbledore explained that ancient wizards’ wars had created Sin, a disaster that had once nearly wiped out wizards and disrupted the transmission of Ancient Magic and Runes.
• Dumbledore told Sean that Sin had been released again and identified him as Pride, its incarnation and the first of the Seven Deadly Sins.

Sean learned that he carried the bloodline of Sin and was destined to awaken its dark power, potentially causing a catastrophe, but he resolved to control it through his choices. Dumbledore warned that Sean’s awakening could trigger the other six descendants and might be hastened by someone behind the scenes, then gave him notes on Animagus transformation.

• Sean asked Dumbledore how he had identified him, and Dumbledore explained that Seers had linked Sean to Sin’s bloodline and that Hogwarts’ Book of Admittance had recorded his birth.
• Sean learned that the prophecy described his bloodline awakening into dark power, though Dumbledore believed Sin could be transformed into virtue through Sean’s choices.
• Dumbledore told Sean that Harry and Neville also carried Sin’s bloodline, that Sean appeared to lead the seven descendants, and that Daisy was not one of them.
• Dumbledore warned that someone behind the scenes might be trying to release the Pride within Sean, while only Sean could release or suppress the true Sin.
• Dumbledore said Sean’s bloodline would awaken in six years, when he graduated from Hogwarts, and gave him a notebook of notes on Animagus transformation.

After learning that the prophecy concerned his connection to Pride, Sean left Dumbledore’s office questioning the different ways Dumbledore and Grindelwald were guiding him. He returned to the Ravenclaw Common Room, where he found Hermione and Daisy asleep together and urged them to go to bed.

• Dumbledore reassured Sean that he would keep an eye on him and encouraged him to study so he could suppress Pride.
• The headmasters’ portraits questioned Dumbledore about Sean, the prophecy, and the sacrifices it might require, while Dumbledore refused to reveal the prophecy’s final part.
• Sean wondered why Grindelwald’s approach differed from Dumbledore’s and compared their guidance to parents with different ideas about raising a child.
• Sean answered the Bronze Eagle Knocker’s question and entered the Ravenclaw Common Room after checking that no one was nearby.
• Sean found Hermione and Daisy asleep together, and they woke when he returned and told them to go to bed.

After learning that the prophecy called him “Pride,” Sean embraced his own ambition rather than submit to fate. The next day, Snape rewarded him for brewing a good Invigoration Draught, and Sean secretly studied Dumbledore’s instructions for becoming an Animagus.

• Sean kept the prophecy from Hermione and Daisy, then decided to outdo the role of “Pride” by standing tall and succeeding.
• Snape inspected Sean’s Invigoration Draught, awarded Ravenclaw one point, and gave Sean two bottles of Nutrient Potion.
• Harry questioned why Snape had praised Sean but continued deducting points from him, and Sean joked that Harry would have to suffer alone.
• Sean returned to the Common Room after dinner and used a Confundus Charm to conceal Dumbledore’s Animagus instructions from others.

Sean began practicing the first step of Animagus transformation with a jade leaf and explained the process to Hermione, who learned that he was also secretly keeping a Swooping Evil. He reassured her that he would prepare carefully, while Hermione reluctantly accepted that she was covering for his rule-breaking.

• Sean read Dumbledore's annotated Animagus instructions and practiced keeping a jade leaf in his mouth.
• Hermione questioned Sean about the dangerous, potentially illegal transformation, and Sean revealed that Dumbledore was guiding him.
• Sean told Hermione that he had been keeping a Swooping Evil, alarming her and prompting her to ask what other rules he had broken.
• Sean calmed Hermione, then let her inspect the instructions; she returned the notebook and urged him to proceed cautiously.

Sean continued preparing for Animagus practice while reassuring Daisy that she should remain in Hogwarts, then spent time with Hermione and his magical creatures in the Room of Requirement. The chapter left Sean still practicing with the jade piece and Hermione reading nearby.

• Sean reassured Daisy after she told him that her father had advised her to stay in the castle.
• Sean gave Daisy Snape's Nutrient Potion, and she accepted it happily.
• Sean and Hermione went to the Room of Requirement to feed Naja, Pudding, and Dave.
• Hermione read in the Room of Requirement while Sean practiced with the jade piece in his mouth.

Sean continued practicing to become an Animagus despite Hermione's concern, then joined her and Hagrid in meeting Nearly Headless Nick, who invited them to his Deathday Party. On Halloween Eve, Sean and Hermione left the Great Hall feast and headed underground to attend it.

• Sean practiced with real leaves, while Hermione urged him to postpone becoming an Animagus, but he remained determined.
• Sean and Hermione met Hagrid, who thanked Sean for helping Fang and said he remembered little about his trip into the Forbidden Forest.
• Nearly Headless Nick told Hagrid that the Headless Hunt had rejected him again and invited Sean and Hermione to his five-hundredth Deathday Party.
• Hermione accepted Nick's invitation, and Hagrid warned her that Deathday Parties were unpleasant.
• On Halloween Eve, Sean and Hermione left the Great Hall feast and walked toward the underground party venue.

Sean and Hermione attended Nearly Headless Nick’s Deathday Party, where they learned that several ghosts had stayed away because they sensed things were unsettled. They left early because of the cold and foul food, but Mrs. Norris urgently approached Sean in the corridor.

• Sean and Hermione entered Nick’s sparsely attended Deathday Party and spoke with Edmund Grub about why outside ghosts had declined their invitations.
• Edmund said the Wailing Widow had stayed away because she sensed that things were unsettled, though he dismissed the warning as an annual occurrence.
• Sean spotted Moaning Myrtle while Peeves teased her, but he and Hermione left the party because the cold and stench made them uncomfortable.
• Sean and Hermione headed toward the stairs, where Mrs. Norris meowed anxiously at Sean.

Sean found Filch and Edmund Grub petrified beside a message declaring that the Chamber of Secrets had been opened, and recognized the Basilisk as the likely attacker. He warned the students and brought Professor McGonagall and other professors to the scene, where they examined Filch in the Hospital Wing.

• Mrs. Norris led Sean and Hermione to Filch and Edmund Grub, both petrified beside a threatening message on the wall.
• Sean summoned Dave to protect himself and Hermione, then hurried with her toward the Great Hall.
• Sean warned the departing students to return inside, using a spell to get their attention when they ignored him.
• Sean told Professor McGonagall about the attack, and she ordered the students back into the Great Hall and sent professors with him to investigate.
• Professor McGonagall deducted five points from Slytherin for Trevino's false accusation and awarded Ravenclaw thirty points for Sean's actions.
• The professors examined Filch in the Hospital Wing, where Professor Flitwick said he had never seen the magic that petrified him.

Sean reasoned that a Parselmouth had released a Basilisk from the Chamber of Secrets and explained how it could have petrified Filch and Edmund without killing them. The professors considered his theory, and McGonagall said she would tell Dumbledore, who was still away from Hogwarts.

• McGonagall and Flitwick failed to identify the magic that had petrified Filch, while Hagrid brought Edmund to the Hospital Wing.
• Sean told the professors he suspected a Parselmouth was controlling a Basilisk from the Chamber of Secrets.
• Sean explained that Filch may have seen the Basilisk through Edmund and suggested searching the castle pipes and places where spiders had fled.
• Newt questioned Sean's theory, and Sean explained that the Basilisk's gaze could petrify rather than kill when seen indirectly.
• McGonagall called Sean's explanation speculation but said she would report it to Dumbledore, who had not appeared at Hogwarts.

After the Chamber of Secrets was opened, Sean warned the professors that someone other than Tom Riddle might be behind it, and they arranged to protect the students overnight. In the Great Hall, Sean challenged Slytherin pure-blood pride by bluffing that he would pay for proof of the Bulstrode Family’s Muggle ancestry, leaving Jermaine Bulstrode humiliated and isolated.

• Sean told the professors that the Chamber’s opening might be connected to the person who had stolen the key to the Realm of Illusion, and Professor McGonagall ordered the staff to take turns guarding the students.
• Hagrid escorted Sean back to the Great Hall, where news of the Chamber’s opening had frightened the students and emboldened some Slytherins.
• Jermaine Bulstrode taunted Sean about being targeted by the heir, and Sean offered to pay for evidence that the Bulstrode Family had Muggle ancestors.
• Sean threatened to publish the evidence around the castle, prompting Bulstrode to worry that his family’s secrets would be exposed.
• Snape ordered Sean to return to his seat, and Bulstrode realized Sean had been bluffing as the other Slytherins moved away from him.
