Chapter Summaries

Vizet arrived at the All-England Wizard Duelling Competition registration site and chose to enter anonymously. After declining the expensive Anonymous Mask, he began the registration process with his own mask ready.

• Vizet used the competition poster as a Portkey and entered a ruined castle through a magical statue.
• A reception witch explained the anonymous registration form and the protections provided by its Ministry of Magic contract.
• The reception witch tried to sell Vizet an Anonymous Mask for ten Galleons, but he refused and paid for anonymous registration.
• Vizet revealed that Professor Flitwick had warned him about the mask and that he had brought one of his own.
• The reception witch gave Vizet the anonymous registration form to complete.

Vizet registered for the All-England Wizard Duelling Competition under the alias Noth and sensed that a competitor entering a special registration office bore a Dark Mark. He began the Evil Hound assessment as the creatures rushed at him in the dark.

• Vizet declined an anonymous mask, registered as Noth with his own voice-changing magical mask, and asked to raise the assessment difficulty.
• The receptionist explained that Vizet would face a pack of potion-fed Evil Hounds and warned that the organizers would not be responsible for casualties if he could not withdraw in time.
• Vizet sensed a Dark Mark on a robed person entering a separate registration office and decided to tell Dumbledore after returning.
• Several Evil Hounds charged into the square and attacked Vizet, who remained motionless as the receptionist watched nervously.

Vizet used Soul Casting to control weeds and defeat a pack of Evil Hounds during his difficult assessment for the All-England Wizard Duelling Competition. After the next challenge released spiny-backed giant spiders, he brought one down as well, leaving the receptionist wondering how he had done it.

• Vizet reflected on how Soul Casting and ordinary magic could overlap, and considered the soul a guiding North Star within every person.
• Evil Hounds charged Vizet, but Soul Casting made nearby weeds bind and batter them until they could no longer fight.
• Vizet used Whirlwind Sweep to push the defeated Evil Hounds into a corner.
• The assessment released spiny-backed giant spiders, and Vizet used his Night Vision Charm to identify them.
• A spiny-backed giant spider fell into Vizet's weed attack and was bound and battered, leaving the receptionist to wonder whether he had struck it with a Cutting Curse.

Vizet finished the dangerous-creature assessment and swiftly defeated a Troll, then learned from Dumbledore that Sirius Black had apparently entered Hogwarts. He used the Marauder’s Map to check the castle and located Luna safe among the Ravenclaw students.

• Vizet used Soul Casting to bring down Acromantulas and clear several more groups of dangerous creatures.
• Dumbledore sent Vizet a message asking him to search the castle because Sirius Black seemed to have broken in.
• Vizet cut off the Troll’s limbs with Ancient Magic: Improved Cutting Curse, stunning the reception witch with how quickly he defeated it.
• Vizet asked whether any assessment remained and said he would forfeit if there was; the reception witch told him the assessment was over.
• Vizet activated the Marauder’s Map, checked the castle, and used Ancient Magic to locate Luna Lovegood asleep among the Ravenclaw students.

Vizet used the Marauder's Map and Ancient Magic to confirm that Sirius Black had left Hogwarts, while Aberforth warned him that Dementors were searching Hogsmeade. Snape questioned Dumbledore's trust in Remus Lupin, but Dumbledore stood by him.

• Vizet found that the Marauder's Map could locate Remus Lupin but could not find Sirius Black, and confirmed that Sirius had left Hogwarts.
• Vizet sent Dumbledore word that Sirius was no longer at school.
• Aberforth sent Vizet a warning about Dementors searching Hogsmeade and gave him directions to a secret passage back to Hogwarts.
• Vizet transformed into a Phoenix Animagus and left.
• Snape questioned how Sirius had entered Hogwarts and accused Remus of being suspicious, but Dumbledore said he trusted Remus.

Dumbledore rejected Cornelius Fudge’s proposal to let Dementors into Hogwarts and challenged him to experience their presence himself. Fudge instead chose to keep the incident quiet and ordered more frequent Dementor patrols around the school.

• Cornelius Fudge contacted Dumbledore and argued that Dementors should be allowed into Hogwarts to protect students from Sirius Black.
• Dumbledore reminded Fudge that Dementors had attacked students on the Hogwarts Express and proposed that one follow each of them until the Christmas holiday ended.
• Fudge refused Dumbledore’s proposal, agreed to increase patrols around Hogwarts, and asked him to keep the incident confidential.
• Back in his office, Fudge decided to have the Dementors patrol more frequently despite an employee warning that they were growing restless.
• Fudge told the Ministry of Magic employee to manage the Dementors with the Patronus Charm and the additional personnel he had assigned.

Vizet heard Filch’s account of Sirius Black’s break-in and then told Dumbledore about a duelling competition contestant bearing the Dark Mark. Dumbledore agreed to investigate the contestant while Vizet considered how to stop Voldemort’s plan, and they began discussing Sirius Black.

• Vizet ran into Filch, who said Sirius Black had destroyed the Fat Lady’s portrait while trying to enter Gryffindor’s Common Room.
• Filch told Vizet that he believed Black had targeted Harry Potter and revealed that he had shared the secret passage locations with Dumbledore.
• Vizet went to Dumbledore’s office and reported spotting a duelling competition contestant with the Dark Mark.
• Dumbledore said the contestant might be a former Death Eater or someone working for Voldemort and agreed to investigate him.
• Vizet suggested that stopping the contestant from winning the competition could thwart Voldemort’s scheme, and Dumbledore asked for his thoughts on Sirius Black.

Vizet and Dumbledore reasoned that Sirius Black’s first target mattered more to him than staying hidden, and Dumbledore became certain he would return to Hogwarts. Vizet planned to use a vast starlight map and protective tools to find and guard against him.

• Vizet argued that Sirius Black’s first target was probably not Harry and questioned how much the reports about his escape from Azkaban could be trusted.
• Dumbledore said the Blacks were willing to give everything for their goals and concluded that Sirius would return to Hogwarts despite the danger.
• Dumbledore realized he had never verified why Sirius Black had betrayed the family, and wondered whether a link in the events had gone wrong.
• Vizet decided he needed to find Sirius Black and described a starlight map in the Map Chamber that could be modified to track him around Hogwarts.
• Vizet proposed making small protective tools using the map, spirit-and-soul connections, and Mandrake leaves, then encouraged Dumbledore to rest.

After Sirius Black's attack terrified the Fat Lady and left Sir Cadogan guarding Gryffindor Tower, Vizet refined his Marauder's Map notes and faced questions from friends about succeeding in school. The chapter ended with Vizet beginning to explain how students could use their strengths to improve in weaker subjects.

• The Fat Lady spread increasingly dramatic stories about Sirius Black, and the frightened portraits refused to guard Gryffindor Tower.
• Sir Cadogan took over as the temporary guardian, repeatedly changing the password and boasting that he would duel Sirius Black.
• Vizet worked on refining his Marauder's Map notes with what he had learned in Arithmancy and Ancient Runes.
• Fred and George told Vizet that their paper had been approved, then lamented that Professor McGonagall had interrupted their Saturday.
• Neville, Hanna, Fred, and George asked Vizet how to improve their grades, and Vizet began explaining how to use their strengths to study weaker subjects.

Vizet gathered Neville, Hanna, Luna, Fred, and George in the Mystic Corridor to discuss their strengths and weaknesses in magical subjects, then used Swelling Solution and the Engorgement Charm to explore how Potions, Herbology, and Charms connected. The chapter ended as Vizet began preparing a demonstration, with Fred and George listening seriously.

• Fred and George joked about their supposed secret, and Vizet redirected the conversation toward the group’s magical strengths.
• Vizet identified Neville and Hanna’s strengths in Herbology and Fred and George’s skills in Charms, Magical Creature Studies, and self-taught Alchemy.
• The group agreed that Potions was the subject they were least good at, so Vizet brought out ingredients for Swelling Solution and asked them to identify them.
• Neville and Hanna identified nettle and its effects, while Vizet explained that the jars contained Pufferfish Eyes and Bat Spleen.
• Vizet demonstrated the Engorgement Charm on a barrel, and George and Fred explained key details of its incantation.
• Vizet lit a fire beneath the cauldron and began showing how Charms, Herbology, and Potions were connected.

Vizet explained how Charms, Herbology, and Potions worked together by comparing them to the making and lighting of Magical Fireworks, then showed Neville and Hanna how to use shared principles to understand Swelling Solution and the Engorgement Charm. He began a timed comparison with Neville to see whether Neville’s Herbology method could speed up preparing nettles.

• Vizet compared the materials, brewing process, and lighting of Magical Fireworks to Herbology, Potions, and Charms, with Fred and George helping explain how fireworks worked.
• Vizet led Neville and Hanna to identify swelling as the shared effect of Swelling Solution and the Engorgement Charm, and connected the potion’s ingredients to that effect.
• Vizet explained that Herbology could help students save time preparing potion ingredients and asked how nettles could be processed more quickly.
• Neville suggested plucking the leaves and scraping the skin from the stems, so Vizet proposed testing his method against the method in the book.
• Neville put on his gloves, picked up a nettle, and prepared to begin the comparison with Vizet.

Vizet taught Neville, Hanna, Fred, George, and Luna to connect Potions with other magical subjects while brewing Swelling Solution. As the group experimented with a modified formula for longer-lasting magical fireworks, Luna selected feathers and dried bluebells that Vizet thought could improve it.

• Vizet helped Neville process Nettle, then confirmed that Neville's work successfully released its properties into the Swelling Solution.
• Vizet explained how Potions, Charms, and Herbology could support one another, relating their connections to the work of healers.
• Fred and George used the potion and the Engorgement Charm on two Pygmy Puffs, then suggested altering the formula to create different magical fireworks.
• Neville and Hanna proposed reducing the Nettle and increasing the Bat Spleen to strengthen the Pufferfish Eyes' effect.
• The group brewed a modified potion, and Luna added bird feathers and dried bluebells after suggesting the mixture needed something light and floaty.
• Vizet realized Luna's ingredients could make the potion's inflation effect last longer.

Vizet and the others developed an early version of a swelling potion and discussed turning its effects into prank candies. After lunch, Vizet and Luna discovered that the former Dementor’s cloak had become a filament that might serve as a Wand Core.

• Fred, George, Neville, and Hanna tested the first Swelling-Type Swelling Solution, which made a Pygmy Puff float briefly and caused Fred and George’s bellies to swell for a few seconds.
• Fred and George proposed developing a loud-farting prank candy and named possible products, while Vizet planned to write a paper about connecting magical subjects to personal interests.
• Fred and George ended their research to attend Quidditch training after Oliver Wood confronted them in the Great Hall.
• Vizet and Luna talked about magic as a gift containing knowledge, nature, and each person's talents and experiences.
• Vizet showed Luna a filament formed from the Dementor's cloak, and they considered twisting it into a Wand Core because it seemed compatible with Luna's magic.

Vizet and Luna entered the Map Chamber and were ambushed by Serena Pendragon, who tested them with spells and summoned two Armor Giants. Vizet and Luna fought back, and Vizet reached for his experimental Dementor Strand wand as Serena began dispelling his magic.

• Vizet spent two months purifying a Dementor's Cloak, then made an experimental Elm Wood wand with a Dementor Strand core.
• After Halloween, Vizet and Luna went to the Map Chamber to modify the Marauder's Map while rain poured outside.
• Serena Pendragon ambushed them with a Stunning Spell and Full Body-Bind Curse, but Vizet blocked and broke the attack before identifying her.
• Vizet and Luna attacked Serena with Disarming and Stunning Spells, and Vizet's Disarming Charm knocked her wand away briefly.
• Serena summoned two Armor Giants, and Vizet and Luna halted their strikes before Vizet used Devil's Snare and an Improved Extinguishing Charm to make one giant attack the other.
• Serena began dispelling Vizet's pitch-black bubble, and Vizet reached for his Dementor Strand wand.

Vizet pushed his mastery of Thunder further, destroyed one Armor Giant, and then controlled its armor to fight the second while he and Luna battled Serena Pendragon. After the test ended, Ominis Gaunt, Anne Salru, and Sebastian Sallow reunited with them and asked why they had come.

• Serena Pendragon freed an Armor Giant to attack Vizet, and Luna disrupted Serena’s defense as Vizet cast Thunder with his Dementor Strand wand.
• Vizet guided a needle-thin lightning strike through the Armor Giant’s helmet and spread it through the giant, destroying its Ancient Magic Power and causing his wand to vanish.
• Luna helped Vizet evade the second Armor Giant’s Spiked Mace, and Vizet used Blood Oath Knight to reassemble the fallen armor and make it fight the remaining giant.
• Vizet and Luna fought Serena while Vizet controlled the Armor Giant, until Ominis Gaunt called a halt and introduced them to Sebastian Sallow.
• Serena Pendragon praised their performance, Sebastian Sallow noted Vizet’s wand had left his hand, and Anne Salru asked what had brought Vizet and Luna to the Map Chamber.

Vizet proposed adapting the Starlight Map to track Sirius Black, and learned why its Guardians had kept the map’s function simple. He and Ominis devised a way to use the Marauder’s Map to mark Sirius as a moving trial location, while Serena offered Merlin Trial Ruins as reference points.

• Vizet explained Sirius Black’s escape and proposed giving the Starlight Map functions like the Marauder’s Map.
• Ominis and Serena explained that the Starlight Map had been created to guide future Guardians and needed to remain stable.
• Vizet reasoned that the Starlight Map could locate someone by treating that person as a moving trial location, but Sebastian and Ominis noted they would need information about Sirius.
• Vizet suggested that Sirius’s involvement in creating the Marauder’s Map could let it help track him, and Ominis said the idea was theoretically possible.
• Anne asked how they would determine the moving trial’s position, and Serena suggested using Merlin Trial Ruins as reference points.

Vizet and the others planned how to use the Starlight Map to find Sirius Black and discussed contacting Olga Goizueta, a Muggle who had been asking about Vizet. Serena Pendragon gave Vizet a rune-filled book taken from the Isaiah Society, leaving him with a new text to decipher when a brief alarm sounded from his pocket.

• Serena Pendragon and the others estimated that turning Sirius Black into a mobile trial location with the Starlight Map would take several months and planned routes through his possible hiding places.
• Ominis Gaunt told Vizet that Scott had caught Olga Goizueta asking about him, and Vizet explained their previous meeting and connection.
• Anne Salru asked for Olga Goizueta's email address so she could contact him, and Vizet gave it to her.
• Serena Pendragon gave Vizet a rune-filled book recovered from the Isaiah Society and suggested that he translate it himself.
• A brief alarm sounded from Vizet's pocket.

Vizet and Luna rushed toward the Quidditch Pitch after the Marauder's Map showed Dumbledore and Snape moving there, while Serena Pendragon and the others prepared to leave. During a stormy match, Harry saw a black dog before Dementors descended and overwhelmed him.

• Vizet's alarm sounded, and the Marauder's Map showed Dumbledore and Snape moving to the Quidditch Pitch, though Sirius Black's name was missing.
• Vizet and Luna took a route toward the Quidditch Pitch and Forbidden Forest, while Serena Pendragon left the location of the Merlin Trial Altar and prepared to depart with Ominis Gaunt, Sebastian Sallow, Anne Salru, and the Armor Giants.
• Harry used the Water and Fire Resistance Spell to keep the rain off as he prepared for the Quidditch match against Hufflepuff.
• Oliver Wood's team took a sixty-point lead over Hufflepuff despite the worsening storm.
• Harry glimpsed an enormous black dog in the stands, then felt the cold and heard cries as Dementors overwhelmed him.

Harry lost consciousness when Dementors swarmed the Quidditch match, but Dumbledore drove them away and safely slowed his fall. After Dumbledore noticed signs of a hidden conflict involving Vizet and the Dementors, he took Harry to the Hospital Wing.

• Hermione and Ron watched anxiously as Harry played Quidditch in a violent storm.
• Dementors surrounded the pitch, and Harry fell from his broom after losing consciousness.
• Hermione and Ron tried to save Harry with spells, but their efforts failed.
• Dumbledore conjured a phoenix Patronus to drive off the Dementors and used a Magical Energy Field to slow Harry's fall.
• Dumbledore remarked that Vizet seemed able to deal with Dementors, then darkened the sky where three clusters of Silver Light appeared.
• Dumbledore said Harry was safe and planned to take him to the Hospital Wing while McGonagall sent the students to warm up in the Great Hall.

Vizet and Luna joined Dumbledore’s Phoenix Patronus in battling a huge swarm of dementors near the Quidditch Pitch. They destroyed many of the dementors, while the survivors fled into the sky as Aurors left the Headmaster’s Office.

• Vizet and Luna followed the Directional Spell toward the Quidditch Pitch and found professors’ Patronuses driving a large swarm of dementors away.
• Dumbledore’s Phoenix Patronus forced the dementors toward Vizet and Luna, who summoned a Golden Eagle and Horned Owl Patronus.
• Vizet created miniature Golden Eagle Patronuses and empowered them with Ancient Magic to attack the approaching dementors.
• Vizet and Luna coordinated with the Phoenix Patronus, destroying many dementors and scattering their cloaks across the Forbidden Forest.
• After Vizet saw Aurors leaving the Headmaster’s Office on the Marauder’s Map, Luna recalled her Patronus and the remaining dementors fled.
