Chapter Summaries

Fudge and Umbridge discussed how to rein in Dumbledore and Amosta Breen, fearing Breen’s growing influence and his agreement to allow MACUSA Aurors into Britain. They decided to place a Ministry loyalist at Hogwarts to spy on them, but had not yet chosen who to send.

• Delix reported that Sirius Black had taken leave to meet Breen and Remus at a Muggle airport.
• Umbridge urged Fudge to expose Harry Potter’s case to force Dumbledore and Breen to compromise with the Ministry.
• Fudge hesitated to target Harry because he was a valuable trump card, then proposed infiltrating Hogwarts to monitor Dumbledore and Breen.
• Fudge said the Ministry needed a loyal agent who could withstand hostility at Hogwarts, but he had not yet named the person.

Amosta, Remus, and Sirius returned to London, where Sirius reported that the Ministry was suppressing news of Voldemort’s return and that the Order of the Phoenix was struggling against rising dark activity. Amosta noticed they were being followed and led the group into a trap, where they captured Amelia.

• Amosta and Remus landed in storm-lashed London, and Sirius met them at the airport.
• Sirius told Remus and Amosta that Fudge was blocking Dumbledore from speaking publicly about Voldemort’s return.
• Sirius reported that Dark Wizards were flooding into Britain while the Order of the Phoenix recruited Frank, Alice, and Bill.
• Amosta sensed a follower and led Sirius and Remus into a side passage without confronting the figure in the crowd.
• Sirius and Remus ambushed the gray-clad follower and discovered that she was Amelia.

Amosta questioned Amelia about resigning from MACUSA and coming to Britain, then urged her to return to New York for her safety and family. Amelia insisted she had come to support him, revealing that her parents had encouraged her to go.

• Kreacher welcomed Amosta, Sirius, Remus, and Amelia to the Black family home, while Amelia wondered why the house-elf treated Amosta as its master.
• Remus and Sirius left Amelia alone with Amosta in the dining room so they could talk privately.
• Amosta asked how Amelia had entered Britain despite Fudge's order barring MACUSA Aurors, and Amelia explained that she had resigned.
• Amelia said the political fallout over Thrak Grevis had made her lose faith in working for MACUSA, and Amosta offered her a job in the United States instead.
• Amosta warned Amelia that Voldemort might target her and urged her to return to New York, but she said she had come to stand by her family.
• Amelia told Amosta that her parents knew everything and had begged her to come care for him.

Amosta argued with Amelia about her decision to leave MACUSA and join the fight against Voldemort, but Sirius and Remus helped them reach a compromise. Amelia stayed at the Black family manor and planned to work at the Learning Machine Workshop while she learned about the British wizarding world.

• Amosta warned Amelia that joining the war could put her in danger, while Amelia insisted that her parents knew the risks and that she wanted to help him and join the Order of the Phoenix.
• Sirius and Remus interrupted the argument, and Remus explained why Dumbledore would not quickly admit an unfamiliar witch to the secret Order.
• Amosta and Amelia reached a preliminary agreement that she would work at the Learning Machine Workshop before deciding whether to join the resistance.
• Amosta agreed that Amelia could stay at the protected Black family manor, and he told her they would go to Diagon Alley the next day.

Amosta took Amelia to The Leaky Cauldron to show her the route to Diagon Alley, where they encountered a dispute over counterfeit armor. Amelia tried to intervene, but Amosta’s presence silenced the pub and drove both groups away.

• Amosta explained magical travel and Apparated with Amelia to a Muggle street near The Leaky Cauldron.
• Amosta led Amelia into the pub and explained its role in the wizarding world.
• Amelia and Amosta found underground wizards arguing with Nordic wizards over fake armor and a disputed contract.
• Amelia shouted at the groups to stop fighting, and the pub fell silent when everyone noticed Amosta beside her.
• The two groups put away the armor, repaired the table, paid Tom for the damage, and left through the back door.
• Amelia laughed at the strange atmosphere left behind in the silent pub.

Amosta brought Amelia to Diagon Alley after hearing Old Tom describe a rise in violent and unexplained attacks across Britain. He headed for Gringotts to investigate an item he had acquired in New York, though he was unsure whether it would be useful.

• Amosta stopped a fight at the Leaky Cauldron, where Old Tom welcomed him and described recent attacks and disturbances that the Ministry was investigating and keeping out of the Daily Prophet.
• Amosta told Old Tom to send a letter to Hogwarts if trouble returned to the tavern, and promised to visit when he could.
• Amosta brought Amelia into Diagon Alley, where she marveled at its busy shops and compared it favorably with New York.
• Amelia thought Amosta was going to Gringotts to withdraw money for her, but he clarified that he carried his wealth with him and wanted to investigate something he had acquired in New York.

Amosta brought Amelia to Gringotts to open a vault and encountered Old Nott, a registered Death Eater, who grew nervous when Amosta alluded to their meeting at Voldemort’s resurrection. After explaining the remaining Death Eaters to Amelia, Amosta asked Bogrod to appraise a crest he suspected was the key to an ancient family vault.

• Amosta advised Amelia to open a vault at Gringotts, and she handed over her wand as a token.
• Old Nott recognized Amosta, became frightened by his reference to their previous meeting, and learned that Amelia had joined Amosta’s Learning Machine workshop.
• Amosta told Amelia that Old Nott was a registered Death Eater and explained that some former followers of Voldemort had escaped judgment and returned to him.
• Amosta showed Bogrod the Slytherin Family Crest he had recovered from the Basilisk’s stomach and asked him to appraise it as a possible vault key.

Amosta brought an ancient Slytherin crest to Gringotts, where Bogrod identified it as the key to Salazar Slytherin’s personal vault. The vault had remained sealed for a thousand years, and Amosta wondered why Slytherin seemed to reject him.

• Bogrod examined Amosta’s crest, recognized its ancient Goblin markings, and went to consult Gringotts records.
• Amosta told Amelia that the crest belonged to Salazar Slytherin and explained that Newt Scamander had found it inside the Basilisk’s fang.
• Bogrod returned with a record confirming that the crest opened Salazar Slytherin’s personal vault, not the reclaimed Slytherin family vault.
• Bogrod explained that the vault’s agreement with Gringotts made the crest’s bearer its owner and that no one had brought the token in a thousand years.
• Amosta considered Slytherin’s apparent rejection of him and suspected it might relate to his origin beyond their world.

Amosta Breen and Amelia rode a Gringotts mine cart to visit Salazar Slytherin's vault, only to discover that rising magma had swallowed its location. Amosta rescued Bogrod from the cart before it plunged into the lava, and Bogrod admitted the vault was probably inside the magma.

• Bogrod offered to take Amosta and Amelia to Salazar Slytherin's personal vault, and Amosta agreed.
• Bogrod led Amosta and Amelia through Gringotts' underground tunnels in a mine cart, and Amosta changed their bodies into phantoms to ease the ride.
• Bogrod explained that an ancient underground cavity connected to the earth's core lay beneath Diagon Alley as the cart approached a vast magma-filled cavern.
• Amosta pulled Bogrod onto a rock platform and protected it with a magical barrier while their cart plunged into the magma.
• Amosta questioned Bogrod, who admitted that rising magma had likely engulfed Slytherin's vault.

Amosta entered the lava beneath Gringotts to find Salazar Slytherin’s vault, convinced its protections had preserved it. He opened the ancient door with the Mithril family crest and the command “Open,” revealing access to the vault.

• Amosta questioned Bogrod about the vault’s location, and Bogrod described its door and keyhole beneath the lava.
• Amosta reassured Amelia and entered the lava, shielding himself with golden flames as magical energy surged around him.
• Amosta found Slytherin’s intact stone door among the abandoned vaults and fitted the Mithril family crest into its recess.
• When the door remained closed, Amosta hissed “Open,” awakening the seven stone snakes and making the lava recede.
• The ancient stone door swung open as Amosta reached the platform before it.

Amosta entered Salazar Slytherin’s vault beneath the lava and discovered that its defenses were beginning to fail. Slytherin’s gift was a mysterious potion and manuscripts, and Amosta recognized the potion’s name as Soul Nourishing Potion.

• Amosta entered the cavernous vault and found emeralds embedded in its walls, along with a black wooden box on a stone platform.
• Amosta considered whether Slytherin’s gift might help him reach the stars and recover his sealed memories, but he could not identify what the box contained.
• The emerald barrier protecting the vault began to weaken as the magic in the stone door grew sluggish.
• Amosta opened the box with his wand and found a golden potion filled with tiny transparent creatures and a stack of manuscripts.
• Amosta read the manuscript’s first line and realized the potion was called Soul Nourishing Potion.

Amosta returned to the lava lake as it erupted into a catastrophic upheaval, threatening to destroy Diagon Alley. He fought to contain the lava but realized he lacked the strength to stop it from rising, then noticed a possible way forward.

• After the emerald barrier vanished, Amosta sensed the lava's roar and the vault began to shake.
• Amelia and Bogrod waited on a rock platform until violent tremors and lava blasts cracked the wall beneath them.
• The platform collapsed, but Amosta rescued Amelia and Bogrod and brought them to a tunnel high above the cavern.
• Amosta flew over the boiling lava and used lightning and golden flames to destroy the lava pillars threatening the cavern.
• Unable to stop the lava lake from rising, Amosta froze after a sudden thought about crossing the barrier.

Amosta realized that the Soul Nourishing Potion from Salazar Slytherin's vault was a test and threw it into the rising lava, where it triggered a reaction that solidified the molten lake. Emeralds embedded in the cavern then formed a magical network around him, which he recognized as a domain.

• Amosta examined the Soul Nourishing Potion and considered whether it could help him cross the final barrier in magic.
• Amosta recalled the Basilisk's unusually low soul activity and realized that the potion reduced soul activity rather than nourishing the soul.
• Amosta concluded that Slytherin had created tests involving both the potion and the rising lava, then threw the vial into the lake.
• The potion spread golden light across the lava, causing it to solidify as an unseen voice expressed dissatisfaction.
• Emeralds flew from the rock walls and connected through channels of magic around Amosta, who recognized their formation as a domain.

Amosta completed an examination of Salazar Slytherin’s Domain and demonstrated how it dismantled unfamiliar spells. After leaving Gringotts with Amelia, he warned her to stay close to Remus and returned to Hogwarts to prepare new Triwizard Tournament events.

• Amosta watched Slytherin’s Domain form from more than a hundred magical nodes and tested it with Fiendfyre and a group Stunning Spell, which it analyzed and neutralized.
• Amosta told Bogrod that the cooled magma had made the underground cavity safe, then reminded him to keep the incident confidential.
• Amosta warned Amelia that the British wizarding world was dangerous and advised her to stay close to Remus.
• Amosta told Amelia he was returning to Hogwarts to devise new Triwizard Tournament events after Voldemort’s appearance disrupted the original plans.
• Amelia asked to attend the Tournament, and Amosta invited her to come with Sirius and Remus before leaving for the Hogwarts Express.

• Dumbledore handed Amosta an official Ministry letter proposing that someone be placed at Hogwarts, and Amosta questioned whether the Ministry had asked his opinion.

Amosta and Dumbledore discussed Fudge’s attempt to install Umbridge at Hogwarts, and Amosta proposed using Lucius Malfoy to trap the Minister and advance Hogwarts’ autonomy. After they left Hagrid’s Hut, Hermione, Ron, and Harry emerged from under the Invisibility Cloak, and Hermione asked Harry whether his scar had hurt again.

• Amosta and Dumbledore agreed that refusing Fudge’s request could lead the Ministry to pass laws interfering with Hogwarts.

• Amosta told Dumbledore that the Slytherin Family Crest had opened Salazar Slytherin's Vault and that he had gained something there, but Bogrod had revealed limited information to Old Nott.
• Dumbledore and Amosta recognized that Voldemort's fear of Amosta's discovery warranted a thorough investigation.

Old Nott reported that Amosta Breen had returned and opened a very ancient family vault at Gringotts, alarming Voldemort with the possibility that Breen had found something connected to his Horcruxes. Voldemort turned his fury on Nott for failing to learn whose vault it was.

• Old Nott arrived at Malfoy Manor and found Voldemort punishing Lucius Malfoy for losing the Dark Lord's treasure.
