Chapter Summaries

Vizet analyzed the defenses around Voldemort’s cave, and Dumbledore confirmed that the basin held Regulus’s locket behind a dangerous magical trap. Dumbledore planned to investigate further with Vizet, Harry, Sirius Black, and Lupin, while asking everyone to keep the matter secret.

• Vizet explained how the basin’s liquid might induce despair and trap anyone who drank it, and Sirius Black recognized that Kreacher had said every drop had to be consumed.
• Dumbledore returned from the cave and described its magical restrictions, the Inferi-filled lake, and the locket inside the Stone Basin.
• Dumbledore said the basin’s liquid might contain a Magic Contract and asked Vizet to help identify it.
• Sirius Black, Lupin, and Harry volunteered to join the next investigation, and Dumbledore agreed to take Harry along after Harry promised to protect himself and keep the secret.
• Molly and Dobby served a lavish dinner, while Fred and George joked that Percy’s overtime might be their fault.

After a cheerful dinner, Vizet and Luna returned to Ottery St Catchpole, where they repaired Salazar Slytherin’s cracked locket using Ancient Magic. Luna sensed that the locket had once held a soul, and Vizet hinted that its history involved Regulus Black.

• Fred and George joked with Ron about Percy’s dragon-dung prank and guessed Percy’s big event was competing for a Ministry award.
• Vizet and Luna walked home through the cool night, and Vizet told her what had happened after he met Hao Qi.
• Luna suggested they visit Hao Qi, and Vizet gave her the locket, whose contents had disappeared.
• Vizet found that the Mending Charm alone could not fix the locket, then used Ancient Magic and the charm together to restore it.
• Luna felt a soul-like attraction from the repaired locket and mentioned changes in Sirius and Kreacher, prompting Vizet to bring up Regulus Black’s past.

Vizet joined Dumbledore, Harry, Sirius Black, Lupin, and Kreacher to travel to the cave where Voldemort had hidden a Horcrux. Kreacher’s attempt to bring the group inside went wrong, leaving them on a sea-battered reef as Dumbledore decided they should approach the cave from outside.

• Vizet arrived at Grimmauld Place, where Kreacher welcomed him and Harry ate a meat sandwich prepared by Sirius Black.
• Vizet, Lupin, and Sirius Black discussed adding useful enchantments to magical greaseproof paper while Harry listened and hoped to join their work one day.
• Dumbledore arrived, and Kreacher transported the group toward the cave, but they appeared on a reef outside it instead.
• Kreacher explained that he had been unable to enter the cave with the whole group, and Dumbledore suspected that the cave restricted the number of people entering.
• Dumbledore proposed approaching the cave from outside, while Vizet suggested that the high tide explained why the familiar route was now flooded.

Dumbledore parted the sea with magic and guided Harry and Vizet across the exposed reef, explaining how his deeper self-understanding shaped the feat. Vizet connected Transfiguration to confronting an object’s will and achieving harmony, and the group reached a pitch-black crevice.

• Dumbledore raised a bridge with Transfiguration, but it dissolved, so he divided the waves into two walls of water instead.
• Dumbledore led Harry and Vizet down the reef while maintaining the walls of water, and he told Vizet to treat his technique as a reference rather than copy it mechanically.
• Vizet explained that Transfiguration began with freedom but required firm intent and a clear goal, and Dumbledore described this as placing a hoop around the desired transformation.
• Vizet reasoned that objects had wills of their own and that Transfiguration involved completing a confrontation with them; Dumbledore praised his insight and explained that understanding and following the target could bring harmony.
• Dumbledore told Vizet that each transformation taught him about himself and the world, and the group reached the dark crevice beneath the cliff.

Vizet and Dumbledore explored the cave where Voldemort had hidden a trap, while Vizet sensed that the place might have been renovated by a Guardian. Dumbledore revealed a concealed archway, and Kreacher prepared to cut open his arm as he had before, but Vizet asked them to wait.

• Vizet discussed the Mending Charm and Transfiguration with Dumbledore as the group entered the cave.
• Kreacher led the group through the hall and pointed out the passage he remembered from his visit with Regulus.
• Vizet asked to search the hall for other exits because it felt familiar, and Dumbledore let him investigate separately.
• Dumbledore examined a rock wall and uncovered the outline of an archway with a brilliant white light.
• Kreacher prepared to cut open his arm, but Vizet suggested that they wait.

Vizet discovered a hidden stone chamber belonging to Zygmunt Budge, a former Guardian and celebrated potioneer, and found his magically protected notebook. The notebook revealed Budge’s early experiments with potions, leaving Vizet to study the origins of techniques he had learned from Budge’s work.

• Vizet used Ancient Magic Power to open the concealed Bronze Gate and enter the stone chamber.
• Vizet found that Crabclaws had destroyed most of the books and nests, though the magically preserved potion ingredients remained intact.
• Vizet discovered a notebook bearing Zygmunt Budge’s signature beneath fragile robes beside the sleeping cot.
• Vizet unlocked the notebook with Ancient Magic Power and learned that Budge had begun brewing potions as a child.
• Vizet read Budge’s notes about an ancient Laughing Potion formula and a beauty potion, recognizing connections to potions in Potions Book.

Vizet read Zygmunt Budge’s notebook, learning how Budge’s eccentric nature drove him to leave Hogwarts and devote himself to Potions research. The final pages revealed Budge’s theory that a potion-maker’s state of mind controlled a potion’s effects, and warned Vizet that another Guardian would eventually find his work.

• Zygmunt Budge recorded how his blunt advice about Potions caused conflicts with students and professors, and he left Hogwarts at fourteen after his application to join the Magical School Potions Tournament was rejected.
• Budge settled on Hemetra Island and continued researching Potions, including Laughing Potion, whose formula Vizet believed Budge had changed by adding the ingredient of loud, uncontrollable laughter.
• Vizet searched Budge’s final notes for clues about avoiding Voldemort’s traps and found Budge’s prediction that another Guardian would come to continue his research.
• Budge instructed the future Guardian to brew potions in the appropriate emotional state, explaining that the potion-maker’s mind controlled the result more than the ingredients and brewing steps alone.

Vizet deciphered Zygmunt Budge’s potion theory and discovered that Budge had used his body and soul as potion ingredients to avoid imprisonment. He found a passage to Potions Lake and brought Dumbledore and Kreacher there, where Kreacher recognized the place where Regulus had been.

• Vizet concluded that a Wizard’s knowledge and soul power could improve a potion and planned to share his notes with Snape.
• Vizet read that Zygmunt Budge had made his body and soul part of a potion, then found a sketch of Potions Lake in the notebook.
• Vizet followed the passage to the lake and noticed a green glow where he believed the Stone Basin was.
• Vizet stopped Kreacher from cutting his arm and told Dumbledore about the passage to the lake.
• Kreacher saw Potions Lake, fell to his knees, and cried that Master Regulus had been at its center.

Harry and the others explored the cave lake, where Sirius Black recognized one of the Inferi as a murdered Auror named Andy Jones. Dumbledore recovered Voldemort’s hidden boat from the lake and explained that it was a safe route to the Stone Basin, while Harry wondered if they would need to disguise themselves as Voldemort to use it.

• Lupin noticed that the lake suppressed wand light, and Sirius Black identified an Inferius as Andy Jones, an Auror whose family Voldemort had killed.
• Harry reflected on the victims in the lake and began to understand what his titles as the Chosen One and the Boy Who Lived meant to those who had suffered under Voldemort.
• Kreacher noticed that the boat had disappeared, and Dumbledore reasoned that Voldemort had sunk it to hide his route across the lake.
• Vizet used Magic Eye to spot an invisible chain, and Dumbledore pulled the chain and boat out of the lake with magic.
• Dumbledore explained that the boat was Voldemort’s safe path to the Stone Basin, and Harry asked whether they would need Polyjuice Potion to use it.

Dumbledore, Vizet, Sirius Black, Lupin, Harry, and Kreacher tried to cross the enchanted lake and investigate the emerald liquid on Lake Heart Island. The boat carried Dumbledore and Sirius Black but not Dumbledore and Vizet, and Vizet suspected the basin’s liquid was protected by Contract Magic.

• Harry, Sirius Black, and Lupin joked about Voldemort’s baldness before the group considered how to reach the lake’s center.
• Kreacher found he could cross the lake with one person, but not with two, so Sirius Black proposed using him to ferry everyone across.
• Dumbledore and Vizet could not move the boat together, but it carried Dumbledore and Sirius Black; Vizet then analyzed the lake water with the Skarpen Reveal Spell.
• Vizet and Kreacher reached Lake Heart Island, where Dumbledore showed that ordinary spells could not alter or remove the liquid in the Stone Basin.
• Dumbledore used a goblet to scoop up the emerald liquid, and Vizet suggested it was protected by Contract Magic before casting the Skarpen Reveal Spell.

Vizet discovered that the lake water in the cave was a harmless potion that preserved the souls of the dead, and Dumbledore realized Voldemort had bound him with a Magic Contract. Dumbledore prepared to drink the Stone Basin’s water and endure the despair of the Inferi, while Vizet and the others worried about him.

• Vizet determined that the lake water contained the same potion components as the liquid in the goblet and was harmless to living people.
• Vizet explained that Zygmunt Budge had built the cave’s arrangements and shared Vizet’s identity as a potioneer.
• Dumbledore concluded that Voldemort’s Magic Contract required the drinker to consume all the Stone Basin’s water and experience the Inferi’s despair at death.
• Vizet realized the contract had been established when Dumbledore scooped out the water, and Dumbledore accepted that he would have to drink it.
• Sirius Black and Harry offered to share the burden, but Dumbledore said the contract probably could not be transferred or divided.
• Vizet gripped his Wand and asked whether Dumbledore had to resist the malice carried by the Inferi’s despair.

Vizet and Dumbledore cleansed the despair-tainted liquid in the Stone Basin, then found Regulus's locket and note revealing his plan to destroy Voldemort's secret weapon. Kreacher celebrated completing Regulus's mission as Lake Heart Island began to tremble.

• Vizet cast a cleansing spell over Dumbledore as he drank eleven goblets of emerald-green liquid from the Stone Basin.
• Dumbledore explained that Voldemort had strengthened the dead’s despair with Magical Understanding, making it easier for Vizet’s magic to dispel.
• Kreacher spotted a locket at the bottom of the Stone Basin, and Dumbledore handed it and its note to Sirius Black.
• Sirius read Regulus's note declaring that he had discovered Voldemort's secret and taken the real trump card to destroy it.
• Kreacher knelt before Sirius Black and said he had finally completed Regulus's mission as Lake Heart Island began to tremble.

Harry, Sirius Black, Lupin, and Vizet fought off waves of Inferi at Lake Heart Island while Vizet freed the despairing victims Voldemort had tortured. Dumbledore then held the Inferi back with a Fire Ring and sent Sirius Black to search the lake for Regulus, prompting Kreacher to rush to the shore.

• The Inferi surrounded Lake Heart Island and attacked Harry, Sirius Black, and Lupin, who defended themselves with spells.
• Vizet used Devil's Snare, a cleansing spell, and Fire Shield to bind the Inferi, reveal their memories of Voldemort's victims, and free them in blue flames.
• Vizet repeated the process for two more rounds until Dumbledore told him to rest.
• Dumbledore raised a warm-red Fire Ring that stopped most of the Inferi approaching from across the lake.
• Dumbledore asked Sirius Black to search the lake for Regulus, and Kreacher hurried to the shore to look.

Vizet devised a way to preserve Regulus Black's soul in the lake and possibly let him communicate through a container of lake water. Sirius, Lupin, and Harry went to retrieve Regulus while Kreacher left to find a protected transparent container, and Vizet prepared to attempt the soul-guiding ritual.

• Dumbledore explained that Voldemort's lake water carried a magical trap and that Regulus had been dragged underwater rather than transformed into an Inferius.
• Sirius and Kreacher found Regulus on the lakebed, and Vizet took Regulus Black's Locket and instructed them not to let Regulus break the surface.
• Vizet explained that opening the locket as Regulus was raised could draw his soul into a protected container filled with lake water, though he could not guarantee success.
• Kreacher vanished to fetch a suitable container, while Sirius, Lupin, and Harry entered the lake with Bubblehead Charms to retrieve Regulus.
• Vizet told Dumbledore that Regulus's soul remained in the lake because of Zygmunt Budge's water, which Budge had created to avoid imprisonment after death.

Vizet opened Regulus Black's locket as Sirius Black and the others lifted Regulus's body from the lake, revealing a vortex drawing in his soul. Dumbledore destroyed the vortex with a powerful strike, leaving the group to face what came next.

• Kreacher brought a magically protected crystal jar, and Dumbledore judged it suitable for storing the lake water.
• Vizet warned Dumbledore that a vortex might appear when he opened the locket, and Dumbledore asked him to mark its location with spherical flame.
• Vizet opened the locket as Sirius Black, Lupin, and Harry pushed Regulus Black's body out of the lake.
• A faint light rose from Regulus Black and drifted toward a pitch-black vortex, but Vizet halted it with the locket and marked the vortex with Fiendfyre.
• Dumbledore raised his Wand and unleashed an immense force that made the vortex vanish.

Vizet and Dumbledore restored Regulus Black’s soul from the locket and contained it in a Crystal Jar, where Regulus awoke and learned what had happened since his death. The group discussed Voldemort’s hidden magical objects, and Regulus asked where Barty Crouch Jr. was.

• Vizet placed Regulus Black’s locket in the Crystal Jar, while Dumbledore recovered from the strain of dealing with the vortex.
• Sirius Black and the others reached the shore, and Regulus’s voice emerged from the locket inside the jar.
• Regulus recognized Sirius and Kreacher, then realized he was a tiny ghost inside the jar.
• Dumbledore, Lupin, Harry, Sirius, and Kreacher explained how Vizet had restored Regulus and what had happened since his death.
• Regulus warned that Voldemort had more than one hidden trump card, and he asked where Barty Crouch Jr. was.

Regulus Black described Barty Crouch Jr.’s ambition and devotion to Voldemort before his soul disappeared to rest. After Kreacher took Regulus’s body and Sirius away, Vizet and Dumbledore began freeing the Inferi, whose remaining soul-lights unexpectedly gathered in the air.

• Regulus Black told Dumbledore and Vizet that Barty Crouch Jr. eagerly sought Voldemort’s approval, admired him, and showed no concern about the Death Eaters’ cruelty.
• Regulus Black vanished after speaking, and Vizet explained that his soul would appear again, though its timing and duration were uncertain.
• Sirius reflected on finally getting to understand Regulus and prepared to return with Kreacher, while Dumbledore and Vizet stayed behind to deal with the Inferi.
• Dumbledore lifted the Inferi from the lake in a ball of water, and Vizet used the Ancient Magic: Purifying Cleansing Soul Washing Spell to remove their despair and release them.
• As the Inferi burned away, their faint soul-lights gathered into brighter clusters in midair, a change Vizet noticed only after his final spell.

After the Inferi were freed, the victims’ spirits gathered as starlight and placed a seed inside Salazar Slytherin’s Locket, which Vizet named the Seed of Hope. Dumbledore and Vizet then discussed how to prepare for Voldemort’s possible disruption of the All-England Wizard Duelling Competition finals.

• With the Inferi released, Dumbledore and Vizet watched the victims’ spirits gather into a swirling cluster of starlight.
• Vizet opened Salazar Slytherin’s Locket with Parseltongue, and the starlight entered it and formed a seed.
• Dumbledore explained that the seed was the victims’ hope for Vizet, and Vizet suggested Luna might help remove it and share its fruits.
• Dumbledore warned that Voldemort might cause an accident during the All-England Wizard Duelling Competition finals, and Vizet considered Voldemort’s preference for ritual and spectacle.
• Vizet and Dumbledore planned to seek clues about Hufflepuff’s Golden Cup from Lucius Malfoy, while Dumbledore said he would handle Barty Crouch Jr.
• Dumbledore told Vizet to perform normally at the finals, and Vizet promised to give a good performance.

Vizet discovered that the seed-like thing had sprouted in the Small Garden, where Luna and Frigga were protecting its seedling. The eager little plant seemed drawn to the damaged Wands, and Frigga kept it safe.

• Kreacher thanked Vizet for helping the Black Family, and Vizet gave him a list of dishes Luna liked to prepare.
• Vizet found Salazar Slytherin's Locket trembling, opened it, and watched the seed-like thing fly toward the house.
• Vizet arrived at the Small Garden and found Luna and Frigga watching a green seedling beside the damaged Wands.
• Frigga stopped the Goblins from trampling the seedling, while Vizet used Transfiguration to halt a tumbling Goblin.
• Luna told Vizet that Frigga had protected the spot where the seed fell, and they saw the seedling move toward the damaged Wands.

Vizet and Luna nearly fell together in the garden, but Dobby arrived in time to help them. They transplanted the mysterious seedling among the broken wands, then joined Xenophilius for lunch; the chapter left Vizet concerned that the crowds at the duelling final could make it easy for Voldemort to cause trouble.

• Luna lost her balance and fell into Vizet's arms, and Dobby arrived to help them up.
• Vizet checked Luna's ankle, then examined the newly sprouted seedling with his Magic Eye and Soul Stone Monocle.
• Vizet and Luna dug up the seedling and transplanted it among the broken wands, where its glow became steady.
• Xenophilius called Vizet and Luna inside for lunch after noticing them planting the seedling.
• The All-England Wizard Duelling Competition expanded and transformed its venue to welcome the large international crowd, and Vizet worried Voldemort could exploit it.
