Chapter Summaries

After Voldemort tested Regulus and offered him authority over Bellatrix, Regulus claimed her as family and refused the offer politely. Voldemort removed Bellatrix and departed, leaving Regulus to call back Fiendfyre and preserve the ruined Manor as a warning.

• Voldemort recognized Dumbledore in Regulus's memory, and Regulus explained that he learned from every great wizard.
• Voldemort gave Regulus permission to deal with Bellatrix, but Regulus said she was family and the matter belonged to the Black family.
• Voldemort silently transported Bellatrix, her blood, and her wand away, then told Regulus he looked forward to their next meeting and vanished into darkness.
• Regulus recovered from the mental strain and tested his will against Fiendfyre, noticing that it obeyed him but feared Voldemort more.
• Regulus called back Fiendfyre and chose to leave Lestrange Manor in ruins as a public warning, forcing the family to decide whether to rebuild there or elsewhere.

Regulus recalled the Fiendfyre after it destroyed Lestrange Manor, then left the ruins with Orion. He reassured Narcissa that Bellatrix had been taken away alive, while Sirius watched him struggle to reconcile Regulus’s composed manner with the person he had seen during the battle.

• Regulus compressed the Dragon, Giant Serpent, and Chimera into a small flame and extinguished the Fiendfyre, leaving Lestrange Manor reduced to scorched ruins.
• Orion met Regulus at the ruins’ boundary, checked him over, and left with him without asking what had happened inside.
• Narcissa, Lucius, Sirius, and Walburga waited outside, and Regulus apologized to Narcissa and told her Bellatrix had been taken away alive.
• Lucius offered the Malfoy family’s help with the aftermath and asked to visit Grimmauld Place, and Regulus welcomed him.
• Sirius stayed silent as he wondered whether the Regulus he had seen torturing Bellatrix was the same person now speaking calmly on the lawn.
• The Black family Apparated away.

After surviving Voldemort’s Legilimency, Regulus considered how Voldemort’s fractured soul might affect his magic and reconsidered the divide between light and dark. He entered his mental space to examine the darkness within his own soul.

• Regulus theorized that Voldemort’s magic remained powerful despite his fractured soul, perhaps because his Horcruxes or knowledge of magic compensated for the damage.
• Regulus recalled how Voldemort’s presence stirred Dark Enlightenment and how Bellatrix, Star Orbit Meditation, and his Patronus responded without suppressing the darkness.
• Regulus concluded that light and dark were different forms of magic shaped by a wizard’s choices, and resolved not to limit himself to either side.
• Regulus entered his mental space and saw that the darkness between the stars in his soul was not empty.

After facing Voldemort, Regulus examined the light and darkness within his soul and recognized a personal dark power he could develop. He also realized his wand was growing fond of combat magic, leaving him to consider how wands shape their users and whether he could transcend their role.

• Regulus identified his drive to organize, control, and gain power, along with his loneliness, as parts of his own nature, distinct from Voldemort's influence.
• Regulus resolved to discover and cultivate a dark power rooted in his soul that could complement the light of his Patronus.
• Regulus reflected on Voldemort's extraordinary magical achievements and regretted that their encounter had yielded no exchange of knowledge.
• Regulus sensed that his blackthorn wand had become more eager for combat magic after their battle and worried its preferences could influence his future choices.
• Regulus decided to keep the wand but seek other options and study whether a wand's role in spellcasting could be replaced or transcended, then settled to sleep.

Lily spent Christmas morning opening presents with her family, but she kept watching the window for an owl from the unnamed person who had become important in her stories. Her father recognized that she was waiting for news from someone, while Lily remained unaware of his growing understanding.

• Lily opened gifts from her parents, Marcia Freely, Susan Hopkins, and her Hogwarts classmates, including bouncing Honeydukes candy and a handwoven charm.
• Lily found a small bottle of hand cream from Sev, but the expected owl and gift from the Black family did not arrive.
• Petunia compared her two simple Christmas cards with Lily's many gifts and noticed Lily's pale purple Handbag.
• Lily repeatedly watched the window and waited for an owl, while her parents quietly observed her disappointment.
• Mr. Evans recalled Lily's unnamed stories about a boy and realized that she seemed to be waiting for news from someone.

Lily received a mysterious black kitten from Regulus for Christmas and recognized her longing to preserve her bond with Petunia. She offered Petunia a chance to name the kitten, and Petunia cautiously accepted it.

• Petunia watched Lily anxiously await a Christmas gift, while Lily's parents heard a knock and found a basket with a black kitten outside.
• Lily recognized the delivery man’s Black family crest and realized Regulus had arranged the gift; the man vanished after confirming she had seen him.
• Lily read Regulus’s note describing the kitten as friendly and easy to raise, then sensed that it carried Magic Power.
• Seeing Petunia withdraw from the magical world, Lily remembered Regulus’s words about longing and decided she wanted to protect their sisterly bond.
• Lily offered Petunia the kitten and invited her to name it, and Petunia awkwardly smiled before gently stroking it.

On Christmas, Severus Snape received potion partnership offers from Silver Moon Potions and Bobbins Herbs and Potions, arranged after he helped Black trap Rababstan Lestrange. He left both offers undecided, unwilling to reveal his connection to Black before he understood the danger from the Lestranges.

• Snape spent Christmas alone in the cold Snape house, thinking about Lily and the reward he expected from Black.
• Two owls delivered letters offering Snape ways to sell his potions through Silver Moon Potions and Bobbins Herbs and Potions.
• Snape compared the offers and recognized that Silver Moon offered better terms and a public connection to Black, while Bobbins offered less favorable terms and greater independence.
• Snape worried that selling through Silver Moon could expose his relationship with Black to the Lestranges and Rababstan Lestrange.
• Snape turned both letters face down, sent the hungry owls away, and left his choice unresolved.

News of Regulus Arcturus Black defeating Bellatrix Lestrange spread through the Wizarding World, prompting families to reassess the Black family’s influence and Regulus’s abilities. The chapter ended with the Nott and Cuthbert families preparing to approach the Blacks, while Abros Mulciber told Hermes to train alongside Regulus.

• Rumors about the fight at Lestrange Manor spread, and the widely accepted account was that twelve-year-old Regulus Arcturus Black had beaten Bellatrix Lestrange.
• Wizards reacted differently to the news: ordinary wizards dismissed it as a simple duel, powerful wizards recognized Regulus’s skill, and ambitious middle-tier families considered approaching the Black family.
• At breakfast, Old Nott told Theodore Nott and Darius Nott to show greater respect to the Black family.
• Old Cuthbert asked Avery what he thought of Regulus, and Avery described his unusual thinking and relentless practice without revealing the magic he had seen.
• Old Cuthbert arranged for Avery to accompany him to Grimmauld Place on December 29 to meet Regulus.
• Abros Mulciber told Hermes to put the Dark Arts aside temporarily and learn by training alongside Regulus.

Orion considered how to use rumors that Voldemort had intervened in the Black family's affairs while Regulus recovered from the mental strain of facing him. Regulus spent the day resting, then fed Baruk Dragon Meat and went downstairs to eat.

• Orion sorted letters probing the Black family's ties to Voldemort and decided to let the mistaken belief that he had contacted Voldemort spread.
• Regulus lay in bed and recovered from Voldemort's Legilimency while Star Orbit Meditation repaired his mental defenses and Saiph began to stir.
• Regulus spent the day too exhausted to move, and Baruk descended from the ceiling to keep him company.
• Regulus called Kreacher for raw Romanian Longhorn meat, and Baruk ate it from a silver tray.
• Regulus cleaned Baruk with a Charm, changed into a house robe, and left for dinner.

After dinner at Grimmauld Place, Regulus met with Orion while Sirius and Walburga privately reacted to the aftermath of his fight with Bellatrix. Regulus decided to leave the political fallout to his father and focus on practicing magic and his research.

• Sirius watched Regulus through dinner, wanting to ask whether he had intended to kill Bellatrix and whether the gray things had affected him.
• Orion asked Regulus how he was feeling and told him to come to the Study after dinner.
• Walburga remained unusually quiet as Regulus left for the Study, while Sirius left the dining room separately.
• Regulus found stacks of letters awaiting Orion and recognized that the Black family would face a wave of political inquiries and overtures.
• Regulus told Orion he was going to practice Magic rather than take part in the family's social and political business.

Regulus discussed his plans to study the Whomping Willow and modify Baruk with Orion, while withholding dangerous information about Voldemort because he doubted Orion could withstand Legilimency. The next morning, Regulus took Baruk to Cornwall, where preparations were ready.

• Orion told Regulus that several Pure-blood families and the Ministry had sent letters, but Regulus declined the invitations and planned to visit the Whomping Willow.
• Regulus asked Orion to obtain Salamanders so he could use their fire resistance in an experiment on Baruk, and Orion agreed to have Agnes arrange it.
• Regulus asked whether Orion could defend against Voldemort's Legilimency; Orion admitted he did not know, and Regulus kept his most dangerous knowledge to himself.
• Orion wondered whether he was holding Regulus back, then hesitated to speak to him about Walburga before letting him leave.
• Regulus told Baruk they would go somewhere the next day, and Orion later confirmed that everything in Cornwall was ready.
• Regulus retrieved Baruk and Apparated to Cornwall.

Regulus visited the Plantation to study two wild Whomping Willows and begin adapting their magical vibrations into a new technique. After calming the trees with Natural Magic Power, he decided the clearing was where he belonged.

• Regulus arrived at the Plantation, where Agnes showed him the clearing and warned him about the wild Whomping Willows’ dangerous attack range.
• Regulus settled into a cabin overlooking the trees and told Baruk they would grow stronger together.
• Regulus sensed how the Whomping Willows conducted and released vibrating Magic Power, but could not yet understand the transformation at their branch tips.
• Regulus spread Natural Magic Power toward the trees, and their alert movements gradually relaxed.
• Baruk excitedly tried to spin a web on Regulus as he watched the Whomping Willows and felt at home.

Regulus used Natural Magic Power to calm the Whomping Willows and studied the details of their Magic Circuits at close range. He left after learning how their branches generated destructive vibrations, planning to observe their attacks on different materials next.

• Regulus spent the day releasing Natural Magic Power until the Whomping Willows stopped treating him as an intruder and their Magic Power flowed calmly.
• Agnes brought Regulus lunch and a raw steak for Baruk, which ate beside him while he continued his work.
• Regulus approached the Whomping Willow and pressed his palm to its trunk as Baruk watched from nearby.
• Regulus traced the Whomping Willow's Magic Circuit and discovered how its branch tips compressed, released, and exploded Magic Power into penetrating vibrations.
• Regulus left the tree and sent a paper airplane toward the eastern Greenhouse, intending to test how the vibrations behaved when they struck different materials.

Regulus tested the Whomping Willow’s attacks and discovered that their oscillating Magic Power destroyed physical structures from within, with repeated strikes growing exponentially more effective. The next morning, he returned to the tree to extract its Magic Power and reproduce the process himself.

• Two Plantation apprentices brought Mu Jins, a wooden board, and an iron pot for Regulus’s experiment, then left after setting them down.
• Regulus released his Natural Magic Power and tested the Whomping Willow’s attacks, finding that its oscillations cracked granite, wood, and iron from within.
• Regulus directed repeated strikes at the same spot on a thick piece of granite and observed Oscillation Stacking, in which each attack exploited the previous cracks and increased the damage exponentially.
• Regulus returned to the Cabin, reviewed what he had learned, and decided to extract the tree’s Magic Power to recreate the process himself.
• The next morning, Regulus entered the Whomping Willow’s range, pressed a hand against its trunk, and began extracting its Magic Power.

Regulus extracted and studied the Whomping Willow’s oscillating Magic Power, then replicated its branching Magic Circuit as a stable Basic Oscillation model. After testing its destructive effects on materials and Gnomes, he confirmed the model worked and found that Baruk enjoyed its vibrations.

• Regulus extracted oscillating Magic Power from the Whomping Willow and tested its effects on minerals, metal, wood, water, and Gnomes.
• Regulus drained one Whomping Willow until it was barely alive, then returned to the Cabin to construct a Magic Power model.
• Regulus refined a tree-shaped branching circuit through several failed attempts and successfully replicated Basic Oscillation.
• Regulus tested Basic Oscillation on granite and Mu Jin, confirming that it reliably shattered dense, rigid materials from within.
• Regulus let Baruk rest in the oscillating Magic Power, and Baruk relaxed and called it comfortable.

Regulus developed and named the Disintegration Charm, refining its incantation, wand motion, and continuous output until it could shatter stone from within. He concluded that the spell worked on any material, though its effectiveness depended on how well the target conducted and sustained the oscillations.

• Regulus combined the Latin roots Concutio and Disrumpo into the incantation Quassare and stabilized its Magic Power model.
• Regulus perfected a reverse-grip wand slash and synchronized its timing with the three-syllable incantation.
• Regulus tested the Disintegration Charm on a seaside reef, shattering it from the inside, and named the spell.
• Regulus maintained continuous output against a large granite rock and shattered it in under a second.
• Regulus tested the spell on waterlogged driftwood and found that its internal gaps absorbed the oscillations, limiting the damage.
• Regulus concluded that the caster had to regard a target as a single whole and let the spell find its weaknesses.

Regulus developed the Disintegration Charm’s area form and considered how Magic Power could compensate for difficulty targeting large objects. He flew offshore to test the spell on an uninhabited island and began building up to a full-power cast.

• Regulus concluded that the Disintegration Charm could target increasingly abstract or large objects if his cognition and Magic Power control were sufficient.
• Regulus reshaped the spell into an omnidirectional area attack and tested it on stones, finding that it shattered nearby rocks but weakened sharply with distance.
• Regulus returned to the Cabin, where Agnes had left food and tea, then set out to find a larger target.
• Regulus searched offshore by Apparating west and found an uninhabited granite island about eight kilometers from shore.
• Regulus hovered above the island, framed it as a single whole in his mind, and raised his wand to cast at full power.

Regulus unleashed Quassare at full power and destroyed a small island with the spell. After watching the sea settle over the vanished island, he recovered some magic and Apparated to a nearby shore cliff.

• Regulus poured his reserves into his Blackthorn and cast Quassare at a small island.
• The spell’s vibrations tore through the sea and cracked the island apart as Regulus increased his magical output.
• Regulus stopped casting, and the island’s halves collapsed into the sea, leaving only a widening ring of ripples.
• Regulus watched the island disappear, then waited for Star Orbit Meditation to restore some of his magic.
• Regulus Apparated to a shore cliff and listened to the wind and waves return to normal.

Regulus analyzed how his Disintegration Charm shattered an island and theorized that its vibration could conduct through discontinuities and trigger a self-sustaining chain reaction. He concluded that such a reaction might collapse a mountain, but the initial Magic Power required could exceed any wizard’s limit.

• Regulus examined the shattered island and realized seawater-filled fissures could conduct the Disintegration Charm’s vibration through the rock.
• Regulus considered whether his perception of the island as a whole let the vibration cross gaps even without a physical medium.
• Regulus imagined separated fragments continuing to shatter if his perception still treated them as part of the original island, and called the idea Chain Conduction.
• Regulus compared the process with nuclear fission and reasoned that fractures could release stored stress energy to sustain the chain reaction.
• Regulus concluded that triggering a self-sustaining reaction in a mountain would require more Magic Power than he or any wizard could provide.

Regulus theorized that the Disintegration Charm could become a self-sustaining chain reaction by converting a target’s mass into Magic Power, potentially creating a nuclear-scale explosion. He identified four hurdles to the idea and turned next to modifying Baruk’s Magic Power structure with the Severing Charm.

• Regulus reasoned that a conversion point could turn a target’s mass into Magic Power, driving oscillations that fractured more material and sustained a destructive chain reaction.
• Regulus imagined applying the process to air, where compression and heating could create plasma and fuel an explosion without a solid target.
• Regulus compared the Disintegration Charm’s physical destruction with the Severing Charm’s conceptual removal of definition, and listed four hurdles: testing Chain Conduction, reaching the critical threshold, learning mass conversion through Alchemy, and improving Magic Manipulation.
• Regulus recalled that Flamel had given him a Metal Ball and invited him to visit on his own, making Alchemy a possible route to solving the energy and conversion problems.
• Regulus noted that five and a half of Orion’s seven stars were lit and believed further progress in Star Orbit Meditation could improve his precision.
• Regulus decided to modify Baruk’s Magic Power form using the reverse application of the Severing Charm and went to the door, where he looked out at the hazy sea.
