Chapter Summaries

Wizet explained his theory to Snape that Wolfsbane Potion uses a process similar to sympathetic magic to affect the soul and counter the werewolf bloodline curse. He demonstrated how the curse damages the soul and began describing how it behaves on the night of a full moon.

• Wizet compared the faint pain and faster heartbeat caused by Wolfsbane Potion to the double heartbeat experienced during Animagus Transformation.
• Wizet and Snape discussed how an Animagus’s animal heart could be understood as a facet of the soul and how suppressing animal instincts could strengthen magic.
• Wizet proposed that Wolfsbane Potion damages the soul to create a temporary “soul atrium,” while the heart carries the lycanthropy curse from the blood into the soul.
• Wizet used a Transfigured body model to show Snape how the lycanthropy curse affected the soul, memories, and emotions.
• Wizet likened the curse’s effects to scabs around the soul and explained that the moon influenced them, ending as he began describing what happened at the full moon.

Wizet explained his theory of how the Wolfsbane Potion protected a werewolf’s spirit and worked with Snape to revise the potion formula. Snape approved several changes, while their research continued with further ingredients to reconsider.

• Wizet explained how Lycanthropy affected the soul and spirit, and described the Soul Atrium as a familiar refuge for the spirit during a full moon.
• Snape concluded that the Wolfsbane Potion had to be taken before the full moon so the spirit could enter the Soul Atrium safely.
• Snape identified unnecessary ingredients in Wizet’s formula, and Wizet proposed using henbane, bay leaves, and coltsfoot to simulate the full moon’s effects.
• After consulting more than ten books, Snape approved Wizet’s proposed ingredients and warned him that other parts of the formula still needed revision.
• Wizet questioned the use of costly, risky Venomous Tentacula juice, and Snape agreed to replace it with witch hazel.

Wizet and Snape examined how Lycanthropy affected a wizard’s soul and how the Wolfsbane Potion could shield the spirit from the curse, then worked together to revise the potion’s formula. Their experiments continued until they reached a bottleneck, leaving Wizet to reconsider the formula.

• Wizet explained his theory that Lycanthropy polluted the soul, influencing the spirit and transforming the body, while the Wolfsbane Potion created a temporary soul atrium for the spirit.
• Snape reviewed Wizet’s experimental notes and proposed removing several overly toxic ingredients while keeping belladonna.
• Wizet suggested simplifying the formula with a whole Wolfsbane plant and Woundwort, and Snape agreed after Wizet cited Have Yourself a Bottled Carnival!.
• Snape criticized claims about widespread agarwood and recommended black walnut shells as a better ingredient for enhancing the potion.
• Wizet and Snape brewed and discussed revisions until nightfall, then stopped at a bottleneck, and Snape told Wizet to rethink the formula and keep track of his time.

Wizet built a laboratory in the Forbidden Forest to study Fenrir Greyback and his memories as the full moon approached. Greyback remained shackled and terrified as Wizet prepared to observe his transformation.

• Wizet decided to revisit the Wolfsbane Potion research because he and Snape had not found the source of its bottleneck.
• Wizet raised a temporary laboratory in a secluded part of the Forbidden Forest.
• Wizet visited the shackled Fenrir Greyback, who tried to spit at him, but Wizet magically forced the spit down his throat.
• Wizet explained that he needed to observe Greyback as the approaching full moon turned him into a werewolf.
• Greyback recalled that Wizet had breached his memory protections and uncovered his past crimes.

Wizet forced Fenrir Greyback to drink an unfinished Wolfsbane Potion, then used a Night-Sight Spell as cover to cut open his chest and study his unusual body. Fenrir accused Wizet of being an executioner, but Wizet hinted that Greyback had once tortured ordinary people in the same way.

• Wizet forced Fenrir Greyback to swallow an unfinished Wolfsbane Potion despite his resistance.
• Wizet cast a Night-Sight Spell on Fenrir Greyback, whose heartbeat intensified and whose body filled with a sense of danger.
• Wizet cut open Fenrir Greyback's chest with a Severing Charm, causing severe pain and drawing his blood into a floating sphere.
• Fenrir Greyback accused Wizet of enjoying torture, while Wizet explained that Greyback's magic-resistant skin required him to cut deeper to examine his body.
• Fenrir Greyback tried to threaten Wizet by invoking Dumbledore, but Wizet dismissed the threat and reminded him of how he had tortured ordinary people.

Wizet tortured Fenrir Greyback to make him recount how he had turned Remus Lupin into a werewolf, then studied the changes in Greyback’s heart after his transformation. He found a werewolf-shaped structure resembling a soul atrium and considered whether it was a failed Animagus form or a magical creature, while observing strange marks around Greyback’s heart.

• Wizet prompted Fenrir Greyback to recall Remus Lupin, and Greyback revealed that he had turned Lupin into a werewolf on his birthday.
• Wizet used the Cruciatus Curse and enchanted restraints on Greyback, then transformed him into a werewolf to examine his heart and soul.
• Wizet observed a werewolf head resembling a soul atrium beside Greyback’s heart and wondered whether it was a failed Animagus form or a magical creature.
• Wizet used the Soul Stone monocle to observe thread-like marks around Greyback’s heart.

Wizet explored Fenrir Greyback’s soul and the Shadow World, forming a theory that consensus magic created Lycanthropy and its werewolf traits. He began testing the idea as a form of Bloodline Magic by using the Human Restoration Spell on Fenrir Greyback and collecting his blood.

• Wizet entered facets of Fenrir Greyback’s soul and found that their memory fragments differed from Greyback’s actual memories.
• Wizet followed the mark from Greyback’s heart into the Shadow World and sensed countless consciousnesses joined by consensus magic.
• Wizet recalled Marlowe Forfang’s notes about ancient Greek werewolf legends and theorized that consensus magic had cursed the first werewolf wizard with Lycanthropy.
• Wizet concluded that Lycanthropy’s magical-creature bloodline was bestowed by consensus magic and recognized it as a form of Bloodline Magic.
• Wizet cast the Human Restoration Spell on Fenrir Greyback, then used the Blood-Draining Spell to collect a blood sample.

Wizet used a modified Human Restoration Spell to isolate Fenrir Greyback’s aggression and werewolf traits, then discovered that the Lycanthropy bloodline curse purified a werewolf’s blood before transformation. He concluded that someone had sought to purify their bloodline and become a magical creature, with consensus magic turning them into a werewolf.

• Wizet observed that the Human Restoration Spell shortened the wolf’s muzzle in Fenrir Greyback’s Soul Atrium and considered isolating Greyback’s negative emotions.
• Wizet combined the Human Restoration Spell with Patronus Charm techniques and used the Mark Extraction Charm to isolate the cruelty in Greyback’s soul.
• Fenrir Greyback lost his werewolf traits and became weak despite the full moon, while Wizet tested blood samples taken from different states.
• Wizet found that Greyback’s bloodline power had been activated or purified, and inferred that the Lycanthropy bloodline curse purified blood before a werewolf transformed.
• Fenrir Greyback’s werewolf traits returned when the spell faded, and Wizet deduced that someone had tried to purify their bloodline and become a magical creature through a process resembling Animagus transformation, with consensus magic producing a werewolf.

Wizet reviewed Marlowe Forfang's notes and realized that Muggles who survived werewolf attacks might not have been true Muggles. After hearing Filch catch Fred and George with a Scouring Charm that behaved unexpectedly, Wizet hurried to investigate.

• Wizet recorded his findings about werewolf wizards, their bloodline, and the effects of Lycanthropy.
• Wizet read that a small number of Muggles could survive werewolf attacks and become werewolves, then suspected they might not have been true Muggles.
• Fred and George taunted Filch as he pursued them through the corridors with Mrs Norris.
• Filch cast Scourgify, and its unexpected effect caused Fred and George to fall.
• Wizet recognized the spell as one stored in the Fake Wand he had made and hurried to find out why it had behaved differently.

Wizet discovered that Filch's Scouring Charm had developed an unusual effect that made Fred and George slip in magical foam. The charm stopped working for Filch when he tried to remove the puddle, and Wizet began tracing its change to Filch's cleaning work.

• Filch confronted Fred and George after his Scouring Charm covered them and the corridor floor in slippery foam.
• Fred and George revealed that they had made the newest batch of Fake Wands and had intended to use them to amuse themselves during their nighttime wanderings.
• Wizet found that Filch's charm affected only Fred and George, then removed the puddle himself after Filch's Vanishing Spell failed.
• Filch explained that his Scouring Charm had acquired a smell and that he had noticed the change after a major castle cleaning at the end of October.

Wizet examined Filch’s Fake Wand after its Scouring Charm began producing bubbles and discovered that its usable duration had run out. Filch’s thoughts and dreams about bubble-making seemed to have influenced the charm, while Wizet reflected on how wizarding families treated Squibs.

• Filch recalled that bubbles appeared when he imagined the Scouring Charm using detergent, and Fred and George suspected him of a prank.
• Wizet explained that he had altered the charm by skipping its detergent-like step to extend the Fake Wand’s usable duration.
• Wizet inspected Filch’s Fake Wand and found that its ten-day usable duration had expired, surprising Fred and George.
• Filch denied practicing with the wand but admitted that he had dreamed about making bubbles and had wondered whether they could trap Fred and George.
• Fred and George mocked Filch for using the bubbles only to trip them, while Filch stroked Mrs Norris and stopped arguing.
• Wizet considered how Squibs were treated as outcasts by pure-blood families and recalled the burned names on the Black family tapestry at Number 12, Grimmauld Place.

Wizet questioned Filch about seeing Hogwarts and Dementors, using his answers to challenge the belief that Squibs were no different from Muggles. He speculated that Squib blood could lead to wizarding ability and suggested that Filch might be able to become a wizard, before Filch suddenly collapsed.

• Wizet asked Filch what he remembered about first seeing Hogwarts, and Filch recalled the castle’s magic and moving staircases.
• Filch confirmed that he could see Dementors and described their appearance, smell, and chilling effects.
• Wizet speculated that Muggle-born wizards descended from Squibs whose magical blood had transformed, and that some werewolves might have been Squibs.
• Fred and George joked that Wizet wanted to turn Filch into a wizard, and Wizet said it might not be impossible.
• Mrs Norris meowed as Filch closed his eyes and toppled unconscious toward the floor.

Wizet told Filch that he might become a wizard, though the most likely outcome was mastering only one kind of magic connected to Mrs Norris. He gave Filch instructions for a potion-like preparation and left him to begin it with Mrs Norris.

• Wizet caught Filch with a conjured cushion, and Filch woke to ask whether he could become a wizard.
• Wizet explained that Filch might master magic through Mrs Norris, whom Fred and George identified as having faint Kneazle blood.
• Wizet gave Filch Mandrake leaves for himself and Mrs Norris, along with strict requirements for dew and their hairs.
• Wizet told Filch to have them chew the leaves, combine them with the dew and hairs in a glass bottle, and carry it with him.

Wizet explained an Animagus-based ritual that could let Filch and Mrs Norris acquire a shared form of magic, then entered the Otherworld to verify it. He returned safely, confirmed the procedure, and gave Filch refined instructions.

• Fred and George recognized that Wizet's ritual was based on Animagus training, and Wizet described its steps to Filch.
• Wizet entered the Otherworld, where two star clusters helped replicate his Ritual Magic into a new star cluster.
• When Wizet briefly stopped responding, Filch feared something had happened and prepared to seek Dumbledore's help.
• Wizet returned, confirmed the procedure was sound, refined a few details, and handed Filch a written set of instructions.

Wizet, Fred, and George discovered that their Canary Creams used Butrielle, a cultivated plant that could replace the hard-to-collect dew in Filch’s Animagus training. Filch asked the twins for some, and they promised to bring him a bottle the next day.

• Filch tried to leave with the Animagus instructions, but Fred and George stopped him and offered to help him gather the ingredients faster.
• Wizet examined the Canary Creams and found that their recipe used a new ingredient in place of seven-day uncontaminated dew.
• Fred and George identified the ingredient as Butrielle, a magical plant cultivated by Neville and Hannah, and Wizet deduced it came from Bubotuber and seven-petaled lotus.
• Wizet explained that Butrielle could safely and reliably replace the dew in Filch’s Animagus training.
• Filch pleaded with Fred and George for Butrielle, and they agreed to bring him a bottle the next day.

Wizet explained to Fred and George how magical creatures, enchanted objects, and sympathetic magic informed the ritual he designed for Filch and Mrs Norris. Fred and George recognized a possible business in creating soulmate bonds between customers and magical pets.

• Fred and George persuaded Wizet to explain Filch's ritual magic in an empty classroom.
• Wizet explained that magical creatures held much of their magic in their bodies, and that wizards could draw on connections with magical objects such as Flying Broomsticks.
• Wizet said the ritual would bring Filch's soul closer to Mrs Norris's, potentially allowing them to hear and speak to each other.
• Wizet explained that the potion combined their blood, chewed Mandrake leaves, fur, Balian dew, and moon magic to encourage harmonious coexistence.
• Fred and George proposed raising Puffskeins this way and selling them as customers' soulmates.

Wizet perfected his Wolfsbane Potion formula and went to Snape for advice, where they discussed Fenrir Greyback and his experiments. Snape approved the new formula, and Wizet began brewing it in his office.

• Wizet told Snape that Fenrir Greyback was in his custody and agreed that Greyback could no longer be considered human.
• Snape asked whether Wizet knew that Greyback had known him, but Wizet redirected the conversation to his improved Wolfsbane Potion formula.
• Snape read Wizet's notes and let him use the ingredients in his office to brew the potion.
• Wizet replaced Mandrake leaves and Death's-head Hawkmoth pupae with Mandrake root and brewed the first portion until it turned silver.
• Wizet began preparing the second portion, and Snape asked whose blood he planned to use; Wizet said it belonged to an M.S.C. employee, not Greyback.

Wizet completed a cheaper, easier-to-brew version of the Wolfsbane Potion and revealed that it had led him to develop a formula for becoming a Werewolf Magus. Snape questioned whether the formula could work without a real werewolf as a reference, and Wizet said he would continue studying Fenrir Greyback.

• Wizet finished brewing his derived Wolfsbane Potion, and Snape confirmed it worked like Damocles Belby's potion while costing less and being easier to prepare.
• Wizet showed Snape how to reveal the Werewolf Magus formula hidden in the notebook, and Snape read through its ingredients and method.
• Wizet explained that Butrielle could replace seven-day-purified dew and that an Extendable Ear could strengthen the connection to the werewolf form.
• Snape warned that werewolves did not exist as magical creatures and that wizards could not transform into magical creatures.
• Wizet said he would keep studying Fenrir Greyback because he believed Greyback could become a true werewolf and provide the formula with a real-world reference.

Snape discovered that Wizet’s notebook contained plans to help Squibs cast magic, including a ritual already being tested on Filch. The remaining theories were untested, and the chapter ended with Wizet proposing to use Lycanthropy’s bloodline curse to break open a Squib’s sealed soul.

• Snape asked Wizet what else the notebook contained, and Wizet revealed his ideas for helping Squibs master magic.
• Wizet explained that he had given Filch a Ritual Magic method based on an Animagus’s Second Form, using Filch’s cat to grant him limited magical ability.
• Snape examined the ritual and judged its theoretical success rate to be at least eighty percent, higher than Wizet’s estimate of sixty percent.
• Snape questioned whether Wizet had learned the idea from Ollivander, and Wizet declined to reveal that part of his research.
• Snape read Wizet’s untested theories, which proposed using the Lycanthropy curse to tear open a Squib’s sealed soul and let their spirit cast spells.

Snape examined Wizet’s plan to use the Lycanthropy bloodline curse to turn Squibs into wizards and realized it could have far-reaching consequences if applied to people with Squib ancestry in the Muggle world. He sent Wizet to show the notebook to Dumbledore, who brought out his old notes on magical history and the Ministry for Wizet to examine.

• Snape read Wizet’s proposed ritual and alchemical method, noting its risks and the costly treatments for possible side effects.
• Snape spotted Wizet’s conjecture that some Muggle-born wizards might actually be Squib-born and worried about the consequences of awakening magic in people with Squib bloodlines.
• Wizet explained that he had formed the idea after reading Marlowe Forfang’s notebook and researching Fenrir Greyback, and told Snape how Dumbledore had introduced them.
• Snape returned the notebook to Wizet and told him to take it to Dumbledore.
• Dumbledore read the notebook, retrieved his student notes on A History of Magic and the Ministry of Magic in England, and asked Wizet to look for something interesting.
