Chapter Summaries

After the champions’ earlier schemes failed to reveal the Black Lake’s defenses, Harry proposed a direct, schoolwide volunteer exercise, and the champions agreed to face the challenge openly. Their recruitment effort began with a bold speech but ended with an almost empty signup desk as students feared public failure and humiliation.

• Hermione judged Operation Phantom of the Theatre a strategic success but admitted the champions had learned nothing about the Black Lake’s defenses, while Fleur, Krum, and Cedric rejected further trickery.
• Harry proposed calling on the whole school for a frontal assault, and Pheobe, Krum, and Cedric quickly agreed.
• Sirius approved the champions’ plan as Glorious Operation and promised volunteers priority reservations for hospital wing beds.
• The champions posted their call and addressed the school, with Cedric announcing that applicants had to pass a spell accuracy and power test.
• Krum rebuffed Draco Malfoy’s offer to fight, and most students avoided the deserted registration desk, wary of failing publicly after the Canary Choir Incident.
• Fred and George sold Instant Courage Candy nearby, leaving Cedric, Pheobe, and Krum standing before the empty desk as students watched and laughed.

Neville’s support inspired Hogwarts’s strongest students to join the Champions’ assault on the defensive array, and Hermione’s team devised a coordinated plan. As the squad began its attack at dawn, Sirius activated the Artist Intervention Protocol to meet their challenge.

• Neville offered his greatsword and led members of the Swiftwind Sword Club to join the Champions’ team.
• A Ravenclaw counter-curse champion, a Hufflepuff, and other elite students joined, forming a spearhead squad of around twenty.

• At dawn, Hermione ordered the squad to begin the operation.

Hogwarts students launched a coordinated assault on the Defensive Magic Array, but its Weasley Artist Intervention Magic Protocol repeatedly turned their attacks into humiliating pranks. The vanguard ended the chapter demoralized and convinced the array had anticipated their every move.

• Fred and George monitored the array’s automatic responses from the command tent while Hermione coordinated the attack through the Thunderbolt Assistant.
• Cedric’s feint team attacked the barrier, but the First-Phase Dance Floor Surprise Protocol made the lakeshore slippery and played clown music as the students fell.
• Hermione recognized that the feint had not drained the array’s core energy and ordered the main team forward while Pheobe used emotional interference.
• The array activated the Gardener’s Blessing Protocol, causing enormous singing sunflowers to bloom from the Ravenclaw counter-curse team’s wands and interrupt their spells.
• For over an hour, the array disrupted the vanguard’s attacks with an escalating series of magical pranks, leaving the students humiliated and demoralized.
• The Ravenclaw counter-curse champion concluded that the array had predicted their tactics and that the supposed 0.7-second opening was either nonexistent or a trap.

Hermione ordered Neville to activate Plan B, and the Swiftwind Sword Club used Professor Douglas’s Combined Sword Formation to strike the Magic Defense Formation with concentrated physical force. They created a visible crack in the barrier before it repaired itself, leaving Hogwarts stunned.

• Hermione ended the magical feint and told Neville to take charge of Plan B.
• Neville formed the Swiftwind Sword Club into a synchronized diamond formation and used the Combined Sword Formation taught by Professor Douglas.
• Harry identified the weakest Physical Node in the defense using the resonance detected by the Thunderbolt Assistants.

The Hogwarts Vanguard Team breached the Black Lake’s defenses using a physical attack, and Douglas declared their victory while crediting the wider lessons of Hogwarts. The stunt drew attention across the wizarding world, as Marauders Power announced a public presentation of its new defense system.

Sirius Black presented Marauders Power Company's Family Patronus Series at a press conference, touting its home defenses and partnership with the Ministry of Magic. He left reporters and Auror officials impressed by a product designed to protect families while keeping enforcement authority with the Ministry.

Remus Lupin packed Tonks's luggage as she prepared to return to the Ministry, and her impulsive embrace left him smiling after she ran off. Meanwhile, Hermione's research revealed that the Champions would face poisoned, fiercely territorial Merpeople in a narrow passage, leaving them to prepare for a brutal close-quarters fight.

• Hermione reported that Merpeople weakened out of water but wielded tridents coated with the deadly poison Tears of the Siren.
• Hermione concluded that the Merpeople would fight to the death to defend the passage, so the Champions would have to face them hand to hand in the narrow terrain.

The Black Lake was transformed into a grand arena for the second task as Cedric Diggory, Fleur Delacour, and Viktor Krum prepared for the dangerous underwater rescue. The champions took their places, and the opening ceremony ended with an unexpected series of congratulatory videos appearing on the screen.

• Fred and George introduced a series of messages from Hogwarts’ distinguished academic guests.
• Bathilda Bagshot urged the champions to combine courage with wisdom, while Wilbert Slinka advised them to seek the logical exceptions in defensive magic.
• Miranda Goshawk stressed precise spellcasting, and Newt Scamander told the champions to understand magical creatures rather than attack them.

Percy, disguised as Barty Crouch, announced that the Second Task was the Black Lake Maze, a three-hour underwater challenge designed by the Marauders Power Company. After the starting cannon sounded, Pheobe, Krum, and Cedric entered the lake using different methods, beginning the competition.

• Krum transformed his head into a shark's and plunged into the water, while Cedric cast a Bubble-Head Charm and entered calmly.

The three Champions entered the lake maze and faced a first section full of prank traps that tested their patience and judgment.

• Pheobe, Krum, and Cedric adapted to the lake and entered the maze as the Weasley Twins commentated for the spectators.
• Krum charged through aquatic plants and was caught by tickling kelp until Pheobe calmed it with a spell.

• Hermione concluded that the trials favored psychological torment over physical harm and that contestants should always read the instructions.

Cedric, Pheobe, and Krum reached the underwater altar where Hermione, Cho Chang, and Gabrielle were sleeping, then faced a riddle requiring them to make a hot pot base. Cedric deciphered the clue, and Pheobe identified three likely ingredients, leaving the challenge unresolved.

• The three champions found Hermione, Cho Chang, and Gabrielle bound and asleep on the altar, but a bubble face blocked their way with a riddle and seven potion bottles.
• Krum attacked the bubble face with a Blasting Curse, which bounced back and knocked him into a rock wall.
• Cedric realized the riddle called for making a hot pot base and proposed creating a dry space around the altar.
• Cedric, Pheobe, and Krum cast Bubble Rise together, forming a large air bubble and summoning a copper cauldron.
• Cedric ruled out four flashy bottles, and Pheobe identified the remaining three as spicy, aromatic, and umami ingredients.

The Champions used a hot pot base to awaken Hermione, Cho Chang, and Gabrielle, but the girls rose as hostile Mirror Combat Constructs and attacked them. As the stands learned about the constructs, Cho Chang watched her mirrored counterpart fight and wondered whether Cedric truly saw her as that powerful.

• Cedric remembered the stirring technique, and Pheobe stirred the cauldron until its aroma awakened Hermione, Cho Chang, and Gabrielle.

• Cho Chang watched the construct modeled on her and blushed as she wondered whether Cedric thought she was that powerful.

• Hermione explained that Professor Holmes's illusions tested the champions' willingness to abandon idealized images of their loved ones.
• After taking a serious wound, Krum stopped holding back and defeated the illusion of Hermione.
• Pheobe saw the other champions fighting, broke free of her illusions, and stunned the image of Gabrielle.

• The fallen Mirror Combat Constructs dissolved, revealing that Douglas had created idealized projections for a trial rather than cursing anyone.
• The champions helped each other up as the Black Tortoise Basalt Altar sank and revealed a dark passage.

Cedric, Pheobe, and Krum emerged from a trial into a Coral Village, where the Merpeople confronted them with the apparent absurdity of risking their lives to rescue people enjoying a hot pot. As the Champions struggled with the revelation, the Weasley Twins explained the hidden challenge to the spectators, who waited to see how the Champions would respond.

• Cedric, Pheobe, and Krum swam through a passage and found Hermione, Cho Chang, and Gabrielle eating hot pot in a magical bubble at the Coral Village.
• Muriel and the Merpeople showed the Champions visions of their ordeal and taunted them with the thought that their sacrifices were pointless because the people they meant to save were comfortable.
• The Weasley Twins announced that the Merpeople had begun a hidden psychological challenge and explained how heroic self-image could distort a rescuer’s motives.
• The Twins described the test’s central question: whether the Champions could focus on what the others actually needed instead of demanding that they suffer to validate a rescue.
• The spectators watched the Champions’ pained expressions and waited for their answers.

Cedric, Pheobe, and Krum realized the Merpeople’s trial had exposed their motives and chose to turn their rescue into a defiant hot-pot feast for the watching audience. After the Champions earned loud applause and prepared to leave, Cedric worried aloud that Douglas might have planned another stage.

• Cedric felt relieved when he saw Cho Chang safe, while Pheobe dismissed the idea that protecting Gabrielle required anyone’s approval and Krum recognized his need for validation.
• The Merpeople chieftain led her people away and opened a path to the surface, but the three Champions joined the others for a hot-pot feast inside the bubble.
• Cedric, Pheobe, and Krum toasted Professor Holmes and joked loudly for the audience, showing that they had seen through the trial and would not follow its script.
• The crowd watched the feast on the Water Vapor Screen, then erupted in cheers and applause for the Champions.
• After eating, the six prepared to rise, but Cedric asked whether Douglas had planned more stages, making the others go pale.
