Chapter Summaries

Regulus asked Dumbledore for a rapid escape route across England in case he encountered Voldemort at the Lestrange Christmas Banquet, and Dumbledore recognized that Regulus was trusting him with his safety. Dumbledore introduced Fawkes as the only possible means of escape, and Regulus stood before the Phoenix to see whether it would choose to help him.

• Dumbledore considered Regulus's pragmatic approach to magic and his willingness to teach Lily Evans, a Muggle-born witch, to summon a Patronus.
• Regulus told Dumbledore he needed a fast way to escape anywhere in England, and Dumbledore inferred that Voldemort was the danger he feared.
• Regulus asked whether someone long absent might have changed, and Dumbledore admitted he did not know what Voldemort had become.
• Dumbledore reassured Regulus that having someone ready to catch him could help him move forward, then explained that Phoenixes could travel past magical protections.
• Dumbledore invited Regulus to speak with Fawkes, and Regulus approached the Phoenix while reflecting on his identity and soul.

Regulus introduced his Starry Sky Kite Patronus to Fawkes, and their encounter revealed a new principle of space magic. Fawkes gave Regulus a feather that would summon him when Regulus needed help, and Regulus left Dumbledore’s office for the holiday.

• Regulus considered Phoenixes’ abilities and wondered whether Dumbledore’s Phoenix Patronus reflected his repeated spiritual rebirth from regret.
• Regulus summoned his Starry Sky Kite Patronus so Fawkes could inspect his soul, and the two birds circled together in Dumbledore’s office.

• Fawkes allowed Regulus to touch his feathers, then plucked one and gave it to him as a way to summon the Phoenix in an emergency.
• Dumbledore explained that Regulus only needed to hold the feather and think of Fawkes to call for help, then wished him a merry Christmas.
• Regulus thanked Fawkes and Dumbledore, left the office, and walked toward the dormitory.

Regulus tested the Severing Charm on creatures Baruk had captured, but the spell instantly reduced a Gnome to ash. Baruk offered other spiders as test subjects before volunteering himself, and Regulus asked Aragog to lend him Baruk; Aragog demanded conditions.

• Baruk brought Regulus captured Gnomes, a rabbit, a bird, and a Centaur to use as test subjects.
• Regulus struck a Gnome with the Severing Charm at its middle setting, and it disintegrated into ash while Baruk panicked.
• Baruk urged Regulus to test the spell on other spiders before trying it on him, and Regulus agreed to take him home.
• Baruk led Regulus to Aragog, who objected to a wizard taking his cleverest offspring.
• Regulus said Baruk was the most suitable spider to borrow, and Aragog asked what conditions he would offer.

Regulus shrank Baruk and took him out of the Forbidden Forest, where the young Acromantula marveled at the world beyond the trees. As they flew toward Hogwarts, Regulus considered the colony’s fear of the castle and began thinking about studying the Basilisk and its venom.

• Aragog allowed Regulus to make one request later, and Regulus told him he was taking Baruk with him.
• Regulus used Transfiguration to shrink Baruk to palm size, and Baruk climbed onto his shoulder.
• After Apparition made Baruk sick, Regulus healed him with Natural Magic Power and told him he was free outside the Forbidden Forest.
• Regulus levitated toward Hogwarts while Baruk admired the grounds, swung from a silk thread, and settled back on Regulus’s shoulder.
• Regulus considered why Aragog kept his colony away from Hogwarts, recalling Dumbledore’s conditions and the Basilisk beneath the castle.
• Regulus thought about entering the Chamber of Secrets next term to study the Basilisk, its venom, and the possibility of higher-quality magic reversing destruction.

Regulus considered how Basilisk venom and Phoenix Tears might affect the boundary between soul and matter, then brought Baruk back to the dormitory and planned to enhance the Acromantula with abilities from other Magical Creatures. He left Baruk hidden safely in his desk drawer and decided to begin the gradual modifications after the holidays.

• Regulus reasoned that Basilisk venom might sever connections between soul and matter, while Phoenix Tears might restore them, and considered investigating the Basilisk in the Chamber of Secrets next term.
• Regulus placed Baruk in a desk drawer and explained that the dormitory was a school where many wizards lived together; Baruk asked if Regulus was their leader.
• Hermes heard Regulus talking to Baruk, learned the creature could kill them, and obeyed Regulus's warning not to search the drawer.
• Regulus planned to strengthen Baruk by adding Salamander fire resistance, Occamy size-changing, Bowtruckle plant communication, and Demiguise invisibility and precognition, one ability at a time.
• Regulus decided to postpone using the Severing Charm until Baruk had grown stronger, then checked that Baruk was settled in the drawer before going to bed.

Regulus introduced his dormmates to Baruk, a palm-sized Acromantula kept small by a Transfiguration spell, and assured them it would behave. Avery became eager to get an Acromantula of his own, while Alex remained worried; the chapter ended at breakfast with Avery still plotting how to keep one.

• Regulus showed Avery, Alex, and Hermes the palm-sized Acromantula and explained that it was dangerous despite its small appearance.
• Alex recognized the spider as an Acromantula and backed away, while Avery grew excited about keeping one himself.
• Baruk wrapped Avery's wrist in spider silk, greeted the boys, and learned Regulus's name before Regulus put it back in a drawer.
• Regulus told Baruk to stay in the drawer and wait for food, then took the others to breakfast.
• Avery questioned Regulus about obtaining Baruk and argued with Alex about keeping a second Acromantula in the dormitory.

Regulus gathered Avery, Alex, Hermes, Lina, and Samuel by the Black Lake to explain that the conflict with Rababstan and the Lestrange family would continue, while promising the others would be protected from its fallout. As they agreed to stand with him, Sirius approached with James Potter, Remus Lupin, and Peter Pettigrew.

• Regulus asked Alex for an update on the plan to catch Rababstan, and Lina volunteered to take part while Samuel remained silent.
• Regulus told the group Rababstan had targeted Costa and Vance, making the dispute personal, and said any consequences would fall between Black and Lestrange rather than reach them.
• Avery, Hermes, Alex, Lina, and Samuel accepted Regulus's explanation and agreed to continue with the plan.
• Avery noticed Sirius approaching along the lakeshore with James Potter, Remus Lupin, and Peter Pettigrew.

• After Regulus prompted him to speak, Sirius said he wanted to go home.
• Regulus realized Sirius wanted to examine his feelings about Grimmauld Place and find a path beyond simply obeying or opposing his family.

• Regulus returned to the Slytherin Common Room while Alex reviewed the group's plan to stop Rababstan's move before the holidays.

• Lily and Regulus left the Library, wished each other Merry Christmas, and went their separate ways.

Rababstan and Snape tried to interrogate Lena Costa with Veritaserum, but Hermes, Samuel, and Lina exposed the plan and stopped them. Snape took the blame and was left injured, while Regulus treated Rababstan’s attempt as enough to settle the matter.

• Rababstan waited in an abandoned storeroom as Snape brought the unconscious Lena Costa and prepared the Veritaserum.
• Hermes burst in, blasted Snape aside, and chased Rababstan, who fled after his spells missed.

Regulus brought Sirius to 12 Grimmauld Place by Apparition, letting him experience the uncomfortable pressure of spatial transit. Walburga greeted Regulus with pointedly restrained warmth, while Sirius tried to guess what had upset her; Regulus ignored his teasing and decided to make a list later.

• Sirius asked Regulus to let him experience Apparition, and Regulus took him to 12 Grimmauld Place with a rough passage through space.

• Regulus ignored Sirius and walked to the living room, deciding to make a list later.

• Sirius joined Regulus, Orion, and Walburga for dinner and noticed he no longer felt driven to flee the family table.

• Regulus told Sirius to join the Study meeting, and Orion accepted his decision.
• Walking upstairs, Sirius recognized that Regulus could alter the head of the family’s arrangements and was more than just the heir.

Sirius revisited his childhood room at 12 Grimmauld Place and found himself less troubled by its memories than before. Regulus settled Baruk in his room and checked on the Bone Box’s effects before Sirius asked him for a robe, annoyed that Regulus had grown taller and broader than him.

• Sirius looked over the divided belongings in his room, recalled an early memory of helping Regulus build a block tower, and watched Muggle children play outside.
• Sirius tried to wear one of his old Black family robes, found it too small, and left his room without changing.
• Regulus settled Baruk on his desk and took out the Rune Box containing the Bone Box.
• Regulus sensed that the Virtual Persona was eager for more Bone Box material and planned to import a larger amount after speaking with Orion.
• Sirius compared his height and shoulders with Regulus, realized his younger brother seemed taller and broader, and asked him to get a robe that fit.

Sirius accompanied Regulus to Orion’s study, where Orion told him he had to attend the Christmas Banquet at Lestrange Manor. Sirius agreed to go and decided to observe the pure-blood families, though Orion’s instructions and the prospect of Bellatrix taking his arm stirred his old distress.

• Regulus used Transfiguration to adjust Sirius’s robe, and Sirius followed him to the study.
• Sirius looked at Orion’s study without his old resentment, treating himself as a temporary guest rather than the Black family’s eldest son.

• Orion outlined the banquet’s etiquette and said Bellatrix would take Sirius’s arm, making Sirius visibly uncomfortable.
• Sirius endured the instructions and nodded, while Orion turned to Regulus and silently questioned why he had let Sirius stay.

• Regulus froze Sirius with Petrificus Totalus and cast Muffliato, leaving Sirius unable to move or hear.

Regulus told Orion that he had awakened his soul and was strengthening it by influencing the world around him, including provoking Bellatrix over the half-bloods he protected.

• Orion watched Kreacher disarm Sirius with House-elf magic, then dismissed the elf without questioning him.
• Regulus told Orion that he had lit up his soul at school and could now see it.
• Regulus explained that Nicolas Flamel had taught him the soul needed to be fed through experiences, choices, and influence on others.
• Regulus said he had allowed Alex Rosier to help shelter two half-bloods, then answered Bellatrix’s warning with “S0?” written in ketchup.
• Regulus told Orion that Rababstan Lestrange had sent Snape to investigate the half-bloods, and Snape had passed the news straight to him.

Regulus told Orion that he planned to use Dark Enlightenment at the dinner to strengthen his position against Bellatrix, and revealed that he had Fawkes's tail feather as an escape option. Orion backed his son’s plans and urged him to act without worrying about the Black family, then told him to deal with Sirius.

• Regulus explained to Orion that he would make Dark Enlightenment appear to be corrupting him at the dinner while keeping it under control.
• Regulus said his plan also involved sheltering Half-bloods, opposing Bellatrix, and implicating the Lestranges; he intended to test how darkness affected his soul.
• Regulus showed Orion Fawkes's tail feather and said it could take him away if the worst happened, though using it would expose the Black family's connection to Dumbledore.
• Orion told Regulus to do what he wanted and not worry about home, affirming his confidence that the Black family would endure.
• Orion noticed that Regulus had grown taller, then returned to his desk and told him to deal with Sirius.
