• Hagrid went into the Forbidden Forest to help its creatures, while Professor Sprout rushed out to protect her greenhouses from the storm.

• Amosta told Ron that impulsive words and actions could lead to lasting regret, and Ron appeared to reflect on the warning as Amosta left.

On the day of the opening Quidditch match, Amosta stayed with the weakened Remus Lupin while Harry prepared to play. As unnatural cold and frost entered the room, Amosta realized a dark force had come to attack them.

During a Quidditch match in a violent storm, Dementors attacked the pitch and Harry fell from his broom. Amosta saved Harry and drove the Dementors away with a colossal winged serpent Patronus, leaving the teachers and students stunned by its size.

• Harry and Cedric searched for the Snitch as the Gryffindor-Hufflepuff match continued in dangerous weather.
• Dementors swept over the pitch, freezing the crowd and causing Harry to fall from the sky.
• Dumbledore slowed Harry's fall, while Amosta burst from his office and crossed the grounds to the Quidditch pitch.
• Amosta summoned a giant silver Patronus that freed the young wizards from the Dementors' influence and sent the creatures away.
• Snape revealed that Amosta's Patronus had once been normal-sized, and Hagrid identified it as a Tengshe; Amosta frowned at its enormous form.

Amosta summoned an enormous Tengshe Patronus that behaved strangely around the Dementors, drawing them into its black wing and then trapping them in a bottle. Dumbledore worried over the unprecedented magic, while Amosta remained in control and refused to surrender the captured Dementors to the Ministry.

• McGonagall, Flitwick, and Dumbledore discussed the gigantic Tengshe Patronus and wondered what explained its size.
• Amosta watched as one of the Tengshe’s white wings turned black and attracted the Dementors, prompting young wizards to fear he could control them.
• Snape suggested Amosta had modified the Patronus Charm, but Dumbledore went to the pitch and learned the effect had never happened before.
• Dumbledore asked whether Amosta could still control the Patronus, and Amosta confirmed that he could.
• At Dumbledore’s request, Amosta dismissed the Tengshe, which coiled around the Dementors and left them trapped in a cold black glass bottle.
• Dumbledore warned that the Ministry would demand the Dementors, but Amosta said the Minister would have to come take them himself.

After Professor Breen’s Patronus drove the out-of-control Dementors away, the students discussed the match and Harry’s fall, while Dumbledore questioned Amosta about the strange magic. Amosta considered the mysterious experiences and lost wand he had kept secret, leaving the cause of the incident unresolved.

• Students from all four Houses debated Professor Breen’s Patronus, and Draco called it advanced Dark Magic.
• Ron and Hermione visited Harry in the Hospital Wing and described the giant silver-winged serpent and the Dementors circling its black wing.
• Harry learned that Professor Breen had demanded Minister Fudge explain why the Dementors had gone out of control, and that the Whomping Willow had likely damaged his fallen broomstick.
• Dumbledore examined Amosta’s silver dragon Patronus in his office, then asked whether Amosta had experiences that could explain the strange events.
• Amosta privately recalled the Druidic prophecy, Avalon, Gryffindor, and the vanished Twin Serpent Wand and Creona.

Dumbledore told Amosta that he sensed a power in Amosta’s soul that did not belong to him and suggested that Amosta might be a Horcrux. Amosta left the conversation understanding that this could explain why he could wield the Twin Serpent Wand.

• Dumbledore said Amosta’s mutated Patronus stemmed from his soul and that he had sensed another power within it.
• Dumbledore explained that he had once been able to see into people’s souls and said the presence he sensed in Amosta resembled something he had encountered before.
• Dumbledore recalled that Tom Riddle had opened the Chamber of Secrets and that Harry survived Voldemort’s rebounding killing curse.
• Amosta concluded that Dumbledore believed someone had made him a Horcrux, like Harry.
• Amosta considered Dumbledore’s suggestion that his memories might have been altered and connected the soul within him to his ability to wield the Twin Serpent Wand.

Dumbledore and Amosta discussed the foreign presence hidden in Amosta’s soul, which Dumbledore suspected might be a soul fragment but could not identify with certainty. Amosta refused to let Dumbledore examine his memories, and they considered whether the Dementors’ unknown creator might somehow be connected to him.

• Amosta noted that Dumbledore had never sensed anything unusual about him until he cast a Patronus before a Dementor.
• Dumbledore described conflicting accounts of the Dementors’ origins and suggested that their creator might have a mysterious connection to Amosta.

Amosta questioned Dumbledore about reaching Azkaban and whether Dementors could be destroyed, connecting them to his investigation of Avalon. Dumbledore explained a theory from Grindelwald that Dementors’ souls and bodies were one and their lives might be linked, but he knew no more because he and Grindelwald had ended contact.

• Amosta asked Dumbledore for Azkaban’s location, and Dumbledore explained that the Fidelius-protected prison could be reached through a Ministry Portkey.
• Dumbledore offered to arrange an authorized visit, but Amosta declined and promised to wait for the right opportunity.
• Amosta asked whether Dementors could be killed, and Dumbledore indicated that even he had no known way to destroy them.
• Amosta asked whether Dementors had souls, and Dumbledore shared Grindelwald’s theory that their souls were their bodies and their life forces might be linked.
• Amosta asked what else Grindelwald had learned, and Dumbledore said they had cut off private contact after certain events.

Amosta questioned Dumbledore about the evidence that Harry was a Horcrux, and Dumbledore used an alchemical device to reveal a snake-shaped trace linked to Harry. As Dumbledore prepared to leave Hogwarts to investigate another possible Horcrux, Amosta demanded to know whether Harry had to die or could be saved.

• Amosta asked whether Dumbledore had evidence that Harry was Voldemort's Horcrux or was only speculating.
• Dumbledore demonstrated an alchemical device that traced magical connections to the soul and showed a snake-shaped trace for Harry.
• Dumbledore admitted he had known since Harry was brought to him as a baby that Tom had made Horcruxes.
• Dumbledore said he had found a clue to another possible Horcrux and planned to leave Hogwarts, entrusting the children's safety to Amosta.
• Amosta asked whether killing Voldemort required killing Harry or whether Dumbledore had found a way to remove the soul fragment safely.

• Amosta challenged Dumbledore’s claim that Harry had to die, and Dumbledore said he had a way to ensure Harry’s safe death without sacrificing him to defeat Voldemort.
• Dumbledore asked Amosta to let Harry and his friends help capture Sirius Black if it could be done safely, and Amosta agreed.
• Amosta left Dumbledore’s office, thinking about selling any Horcruxes he found and returning to monitor the castle.
• Amosta found Snape and Filch accusing Neville Longbottom of trying to leave the castle and warn Black after losing his wand.
• Amosta told Neville he could search the grounds for his wand in the morning and ordered Filch to escort him back to bed.

Amosta told Snape that his troubles might have begun before he was born, while Harry recovered in the Hospital Wing after losing his Nimbus 2000. Hearing that Professor Breen had helped Neville and was skilled at repairing things and dealing with Dementors, Harry began to consider asking him for help.

• Professor Breen explained that he had only reconnected most of the broom’s magical pathways and that it was not truly repaired.
• Professor Breen warned Harry that the broom might manage casual flying but could fail during a Quidditch match.

Amosta gave Harry his modified Cleansweep Seven after Professor Breen confirmed that Harry’s damaged Nimbus could not be used again. Harry asked to learn the Patronus Charm, and Lupin agreed to teach him when his illness-related duties allowed.
