Chapter Summaries

Vivian advised Anduin on how to make his alchemical products more attractive and marketable by improving their appearance, repackaging them, and targeting new customers. Anduin realized he had focused too much on research and began to see new possibilities for his products.

• Vivian criticized Anduin's limited, unfinished-looking products and showed him how she had decorated one of his Defense Amulets as a pendant.
• Vivian suggested casing and decorating the amulets, turning them into different accessories, and selling Communication Charms as matching couples' gifts.
• Vivian proposed redesigning the Protective Gloves and marketing them to Quidditch fans, even though players were forbidden from using their own alchemical tools.
• Vivian pointed out that Anduin could remove the self-inspection device from his pocket watches and sell it to St Mungo's Hospital for Magical Maladies and Injuries.
• Anduin understood that he had kept the scanner in a pocket watch merely out of convenience and recognized the potential of Vivian's advice.

Vivian proposed turning ordinary Muggle-inspired items into stylish Alchemical Tools and suggested Magic Mahjong, then agreed to work as Anduin’s product planner in exchange for a set of tiles. She began designing products by adapting fashions and objects from Muggle magazines.

• Vivian suggested separating Anduin’s self-inspection tool from its pocket watch and creating decorative Magic Clocks, Music Boxes, and Gramophones.
• Vivian proposed making enchanted Magic Mahjong and opening a Mahjong room in Anduin’s shop, but Anduin rejected the parlor idea and agreed only to make a set for her.
• Anduin hired Vivian to design products, and she accepted on the condition that he make her Magic Mahjong.
• Anduin closed the shop and set aside part of the testing room as Vivian’s office, where she could work through the Floo Network.
• Vivian copied attractive designs from Muggle fashion magazines for pocket watches, clocks, Music Boxes, and Gramophones.

Anduin developed a practical product line built around replaceable magical components, then delivered Ministry equipment and brought his products in for hazard assessments. He discovered that Arthur was assessing whether the products broke the law.

• Vivian designed imaginative magical products, while Anduin selected simpler ideas that could be produced and sold soon.
• Anduin planned to outsource physical components to Muggle factories and modify ready-made Muggle items into magical products.
• Anduin adopted a Razor Law business model, selling lamps and gramophones cheaply while earning repeat sales from replacement energy components and music records.
• After more than ten days, Anduin finished a batch of products and improved Humanoid Targets, then brought them to the Ministry with its equipment.
• Anduin delivered the equipment, received the remaining payment, and submitted his products for hazard assessments.
• Anduin discovered that Arthur was the Department of Magical Law Enforcement assessor reviewing whether his products broke the law.

Anduin reopened his expanded Alchemy Shop with a wide range of elegant products and prepared Vivian, Qiqi, and Hog to help run it while he was at Hogwarts. When Meiweis visited Diagon Alley, she found the shop thriving despite Mrs. Primpernel's claim that it had failed and went inside.

• Anduin expanded and reorganized his shop, displaying his products in polished glass cabinets and putting Magic Mahjong on display.
• Anduin hired Vivian to sell products on commission and brought in Qiqi and Hog to learn sales and bookkeeping before term began.
• Qiqi reported no changes in Acelia's routine, so Anduin had her install a concealed Magic Monitor in Acelia's home.
• Meiweis encountered Mrs. Primpernel, who claimed Anduin's Alchemy Shop had closed after selling shabby, overpriced trinkets.
• Meiweis saw the brightly lit shop filled with dazzling displays and entered, while Mrs. Primpernel stared in disbelief.

Meiweis visited the Silver Flash Merchant to buy Tactical Equipment, but Vivian’s sales pitch drew her toward the shop’s flashy civilian products and accessories. Meiweis bought two Defense Amulet accessories and an adult home-use Humanoid Target, then noticed that a Magic Gramophone looked like a modified Muggle item.

• Meiweis entered the shop and Vivian welcomed her with a sales pitch about the grand-opening discount.
• Meiweis questioned why a Tactical Equipment shop displayed so many decorative products, and Vivian explained that the workshop also sold civilian goods and redesigned equipment.
• Vivian persuaded Meiweis to pick up a Defense Amulet brooch and pendant, despite Meiweis’s original plan to buy Protective Gloves and a Humanoid Target.
• Meiweis chose an adult home-use Humanoid Target, rated for spells with a Power Value up to 200.
• Vivian promoted the Magic Gramophones and seasonal records, and Meiweis recognized that a gramophone resembled a modified Muggle item.

Meiweis left Anduin's redesigned shop with far more purchases than she had intended, while its booming business pushed Anduin to expand production. After returning to Hogwarts, Anduin restored order in Slytherin and applied to leave school early, assuring Snape that he would not depart immediately.

• Meiweis bought several unexpected items at Anduin's shop and left Diagon Alley puzzled by the experience.
• Anduin calculated the shop's strong sales and built another Magic Lathe to meet rising demand.
• Anduin entrusted the shop to Qiqi, told her to keep monitoring Acelia, and returned to Hogwarts with Hog.
• Anduin tightened discipline in Slytherin over the first three months of term until the students' habits and conduct improved.
• Anduin submitted an early-departure application, and Snape objected because he feared Slytherin would suffer without him.
• Anduin reassured Snape that Slytherin would be fine and clarified that applying to leave early did not mean he would leave immediately.

Anduin persuaded Snape to approve his early-departure application by presenting a Patrol Striker Certificate that let him use magic outside school. After asking Snape about Acelia Rohl’s wand, Anduin received a vial of Felix Felicis and noticed something unusual about it.

• Anduin explained that he wanted to travel freely during term and showed Snape his Patrol Striker Certificate.
• Snape questioned how Anduin had obtained the certificate, then approved his early-departure application.
• Anduin asked Snape about Acelia Rohl and learned that her wand had been dark-colored, possibly blackthorn or black walnut.
• Snape gave Anduin a vial of Felix Felicis as a reward for helping Slytherin.
• Anduin examined the potion, recognized it, and thanked Snape for the astonishing gift.

Anduin realized Snape had secretly given him the Buffy-Brain Potion years earlier, then heard Qiqi’s report about Acelia Rohl’s late-night trip to Ireland with Ministry officials. Qiqi had seen a dragon near the Ministry group, but had not yet explained what happened there.

• Anduin recognized Snape as the person who had supplied him with the Buffy-Brain Potion and wondered why Snape had helped him.
• Qiqi arrived at Anduin’s room in a dirty Combat Suit and Tactical Vest and reported that something unusual had happened at the Ministry of Magic.
• Qiqi explained that she had tracked Acelia Rohl from the Ministry across Ireland Island after Acelia left work late at night.
• Qiqi followed Acelia to a gathering in western Ireland of dozens of Aurors and more than ten Ministry employees, including a female Auror who had visited Anduin’s store.
• Qiqi told Anduin that she had seen a dragon, but the chapter ended before she described what it had done.

Qiqi told Anduin about a Ministry operation that captured smugglers transporting Peruvian Vipertooth Dragons, and he concluded the smugglers had come from the Americas. Anduin suspected Acelia and the Silver Spear might have been involved in the events that exposed the smuggling operation.

• Qiqi described five chained Peruvian Vipertooth Dragons and several handcuffed suspects at the scene of the Ministry operation.
• Qiqi reported that the suspects wore brightly colored clothing unlike British wizards, and Anduin inferred they had come from the Americas.
• Qiqi followed Acelia's team as they transported the dragons to the Ministry, then told Anduin what she had witnessed.
• Anduin ordered Qiqi to rest at Hogwarts after her overnight investigation.
• Anduin reasoned that the Ministry had prepared to capture the smugglers in advance and wondered what roles Acelia and the Silver Spear had played.

Anduin watched an intruder repeatedly test the defenses of his home in Diagon Alley and try to break in. The intruder failed to get through the magically protected door, while Anduin observed from inside.

• Anduin recorded his questions about Acelia, the Silver Spear, and the smuggling operation, then decided to wait before getting involved.
• Anduin woke to an alarm and used his monitor to locate a cloaked intruder watching Number 277 in Diagon Alley.
• The intruder threw bricks and stones at the windows, testing the house’s defenses without causing damage.
• After deciding the house was empty, the intruder cast Disillusionment and tried to unlock the front door, but Alohomora failed.
• The intruder’s Shattering Spell triggered glowing Magic Patterns and a shock wave, which they narrowly dodged.
• The intruder tried Transfiguration, fire, freezing, and a conjured hammer, but the door remained intact and repelled their attacks.

Anduin lowered his shop’s front-door defenses, allowing Acelia to break in after a long struggle. Acelia searched the unfamiliar shop for restricted items, got distracted by its merchandise, and finally opened the door to the back room.

• Anduin recognized Acelia and secretly weakened the front door’s defenses after worrying she might resort to Dark Magic.
• Acelia repeatedly cast Finite Incantatem until the door’s Magic Pattern vanished, then used Unlock Charm to enter.
• Acelia wore a blank ivory-white mask, checked that the shop was empty, and examined its changed interior.
• Acelia browsed the shop’s new products and was startled when she opened a Music Box.
• Acelia searched the shop and cash register for her target but found nothing, so she tried the back-room door.
• The back-room door opened easily when Acelia cast Unlock Charm, and she let out a relieved breath.

Acelia broke into the Alchemy Merchant House and stole five Anti-Apparition Jammers and five Jamming Interferers from a hidden safe, then concealed the damage and returned home. There, she was confronted by Thunderbird, who had entered without permission.

• Acelia searched the shop's back room and found a locked safe hidden in a cabinet.
• Acelia corroded the safe open and took five Anti-Apparition Jammers and five Jamming Interferers.
• Acelia used Transfiguration to restore the safe, cleaned up, and carefully left the shop without disturbing anything.
• Acelia restored the shop's defenses and Apparated home.
• Acelia sensed danger, drew her wand, and faced Thunderbird as he emerged from the shadows.

Acelia argued with Thunderbird over the failed operation before handing him eight devices stolen from the Ministry of Magic. Thunderbird learned that the Aurors’ improved tactics and tracking relied on equipment from the Silver Lightning Alchemical Company.

• Thunderbird confronted Acelia for taking too long to steal the devices and threatened to hold her responsible for the club’s losses.
• Acelia blamed the failed operation on Thunderbird’s arrogance and his subordinates, then reminded him that she had warned him about the Ministry’s upgraded equipment.
• Thunderbird ordered Acelia to serve the club wholeheartedly and warned her against defying him.
• Acelia handed Thunderbird four Anti-Apparition Jammers and four Jamming Interferers from her Space Bag.
• Acelia explained that the Aurors had used the devices to evade detection and prevent escape, while Tracking Glasses from the Silver Lightning Alchemical Company helped them locate the drop-off site.

Acelia delivered stolen Interference Devices to Thunderbird, who dismissed them while discussing the threat posed by Anduin Wilson and proposing to eliminate him. The chapter ended with Thunderbird mocking Anduin’s Battle Hero title and confidence in his own strength.

• Acelia brought several stolen Interference Devices to Thunderbird, who refused to use them and told her to keep them until the club’s next operation.
• Acelia asked Thunderbird to store the devices in his Safe House, but he rejected her request and insisted she follow his orders.
• Thunderbird asked about Anduin Wilson and said Anduin’s Alchemical Items could disrupt the club’s operations.
• Thunderbird proposed getting rid of Anduin, but Acelia warned that he was an underage wizard, a Battle Hero, and no easy target.
• Thunderbird laughed at Anduin’s title and dismissed his achievements, saying he would welcome the chance to face him.

Thunderbird planned to target Anduin after Christmas while assigning the Silver Spear's Box operation to the Sphinx's infiltration unit. Anduin learned of Acelia's theft, left Hogwarts for his Diagon Alley shop, and awaited an unexpected customer.

• Thunderbird told Acelia he intended to deal with Anduin after Christmas and ordered her to relay anything unusual about the Box operation to the Sphinx.
• Anduin watched Acelia's break-in and concluded she was tied to the smuggling case and likely had accomplices.
• Anduin told Qiqi what had happened and gave her trackers to monitor the stolen Interference Devices.
• Anduin left Hogwarts with Hog and returned to his Diagon Alley shop, where he found traces of Acelia's break-in but chose not to expose her.
• Anduin opened the shop for business, and an unexpected customer walked in.

Acelia returned to Anduin's shop to buy accessories and listen to a record, but she worried that her visit would expose her involvement in the previous night's break-in. Anduin noticed how familiar she was with the shop and led her toward the listening booth, while Hog recognized that her acting was unconvincing.

• Anduin was surprised when Acelia entered his shop again so soon after stealing from it the previous night.
• Acelia froze when she saw Anduin and learned he had left Hogwarts early to focus on his business.
• Anduin questioned Acelia about her tired appearance and Ministry work, making her increasingly uneasy.
• Acelia bought several accessories and asked to listen to the new Christmas Album.
• Anduin pointed out the shop's listening booth and offered to let Acelia try on her accessories, while Hog noticed her clumsy acting.

Anduin and Hog discussed how to investigate the Silver Spear without exposing their strength, while seeking a way to use the Ministry of Magic against the smugglers and find Griffin. As Christmas approached, Anduin’s shop prospered, but he continued surveilling Acelia.

• Anduin rejected Hog’s suggestion to capture Acelia, choosing to stay hidden until he learned more about the Silver Spear and its methods.
• Anduin suspected Acelia had complicated feelings about the Silver Spear and planned to use the stolen Interference Devices to expose the organization.
• Hog and Qiqi agreed to watch the Silver Spear, and Hog vowed to take revenge on the smugglers and Griffin himself.
• Anduin expanded his shop’s Christmas promotions, using expensive window displays to make his affordable products seem like bargains.
• Anduin’s Civilian Products sold briskly, but he continued keeping Acelia under surveillance.

Anduin tracked the stolen Interference Devices after eight of them suddenly moved, while Acelia remained at the Ministry of Magic. He and Qiqi pursued the devices to Dorset and continued toward their target by air.

• Anduin learned that one pair of Tactical Leather Boots had traveled northeast toward the European Continent, but he could not determine where it had gone.
• Qiqi reported that eight Interference Devices had moved while Acelia stayed at the Ministry of Magic, and Anduin ordered Hog to watch her home.
• Anduin and Qiqi followed the devices southwest from London using Qiqi's tracking device and Apparition.
• Qiqi located the target near Dorset, and Anduin gave her a Vitality Nourishing Agent before flying them onward under his Flying Cloak.

Anduin and Qiqi tracked hidden Interference Devices to a strange house in a snowy valley, but found no sign of the people who set them up. Anduin moved closer to investigate and discovered the house was home to many Magical Creatures as someone called after two escaping Kneazles.

• Anduin used his monocle and Echo Glasses to reveal a strange house and eight hidden Interference Devices surrounding it.
• Anduin found no people or footprints near the devices and refused Qiqi’s suggestions to enter the house or shut the devices off.
• Anduin gave Qiqi a potion and told her to hide while he approached the house under concealment.
• Anduin spotted an enormous Augurey, Nifflers, Mooncalves, and Diricawls inside the house.
• Two Kneazles ran through the cat flap, and a young voice called for Hobby and Millie not to run off.

Anduin watched an old man and his grandson, Rov, play with Kneazles in a snowy valley until four masked wizards emerged from underground and seized Rov. The old man prepared to confront them while Anduin realized how the intruders had concealed themselves.

• Rov chased Hobi and Mili through the snow, but they outmaneuvered him and made him fall.
• The old man distracted the Kneazles with a feathered cat teaser and sent Rov back toward the house.
• The old man sensed something unusual and levitated Rov toward him.
• A masked wizard burst from the ground, grabbed Rov, and retreated while three other masked figures surrounded the old man.
• The old man deflected the attacker's spell, and the wizard sealed Rov's mouth when he cried for help.
