Chapter Summaries

Gerald listened as Lupin argued that wizards wielded godlike magic but neglected their physical bodies, then joined Horton and Lupin at Helena Perry's gathering to examine a runic stone slab linked to Paracelsus. When Gerald touched it with his spiritual sense, he discovered it carried a mental imprint.

• Lupin told Gerald that wizards could perform godlike feats, but their neglect of physical conditioning left them frail.
• Gerald, Lupin, and Horton ate together before Horton led them to Helena's gathering in the camp.
• Horton explained that many attendees sought the Philosopher's Stone, while Helena and a few others wanted Paracelsus's necromancy manuscripts.
• Helena Perry presented a runic stone slab that she believed might point to Paracelsus's laboratory and offered to share its secrets with those who deciphered it.
• Gerald touched the slab with his spiritual sense and found that it contained a mental imprint.

Gerald read Paracelsus’s research notes on learning Parseltongue and realized he might be able to acquire the skill himself. After Helena Perry invited the gathered wizards to decipher the tablet, Gerald suspected she had brought them there to find someone to die in her place.

• Gerald used his mental power to read the tablet, discovering coordinates in the Albanian Forest and Paracelsus’s notes on reproducing Parseltongue through study and training.
• Gerald connected Paracelsus’s achievement to his own chance of learning Parseltongue, but hid what he had read from the crowd.
• Helena Perry claimed she had failed to decipher the tablet and offered its information to anyone who could, while warning them against stealing it.
• Chris Horton went to inspect the tablet, and Gerald drew Lupin aside to ask about Helena and her motives.
• Lupin told Gerald that Helena had been a gifted Slytherin in their year, and Gerald proposed that she was seeking someone to die in her place.

Gerald warned Lupin that Helena Perry was using the Stone Tablet to mark wizards and send them into Paracelsus's laboratory as expendable scouts, but Lupin could not stop Chris Horton from pursuing the mystery. The next morning, Gerald and Lupin left the camp to continue their search for Nagini, while Helena tracked the marked wizards toward the laboratory.

• Gerald told Lupin that Helena might be sending other wizards to trigger the laboratory's defenses and that they had no reason to get involved.
• Lupin left Chris Horton at the Stone Tablet, and Gerald slept after the strain of studying it with his divine sense.
• At dawn, Gerald and Lupin found that more than half the camp, including Chris Horton, had disappeared.
• Helena watched the emptying camp and revealed that the wizards who touched the Stone Tablet bore her dark magic mark and were heading toward Paracelsus's Experiment Site.
• Gerald and Lupin left by the northern path, and Gerald used the Map of Albania to check the laboratory's location as they continued their journey.

• Horton gave Lupin his enchanted bag and asked him to send the money to his mother, then died in Lupin's arms.
• Gerald was shaken by Horton's death and reflected that this was the first time he had witnessed someone die.

• A Forest Giant Python watched the fight and considered possessing Helena before noticing Gerald.
• The soul fragment inside the python chose Gerald’s young body as its target.

Gerald helped Lupin drive Helena off with a Thunder-Summoning Art, while Voldemort’s soul fragment watched from inside a giant python. Terrified by Gerald’s lightning, the python fled deeper into the forest.

• Helena and Lupin exchanged powerful fire and water spells, and Lupin summoned rain to extinguish the Fiendfyre that set the forest alight.
• A giant python crept toward Gerald as he watched the duel, and Gerald used Mist Talismans to obscure the clearing and reveal the python with his Qi-Perception Spell.
• Gerald struck Helena with Expelliarmus and joined Lupin in attacking her through the fog, forcing her to divide her attention between them.
• Gerald summoned lightning that shattered Helena’s shield, and Lupin’s follow-up spells wounded her before she escaped by Apparition.
• Voldemort’s soul fragment, hidden in the python, feared Gerald’s lightning and fled into the forest.

Gerald pursued the enormous python he suspected was Nagini and discovered that Voldemort's remnant soul had been possessing her. After Voldemort fled, Gerald tried to capture Nagini with his Beast-Taming Ring.

• Gerald recalled sensing a huge snake surrounded by dark smoke and guessed that it was Nagini, then chased it through the forest while Lupin followed.
• Gerald's spells barely slowed the python, so he used Qi-Driven Object Control to lift and restrain her.

• Nagini broke free, attacked Gerald, and smashed through a tree when he dodged her strike.
• Gerald told Nagini he knew how to break the Blood Demon Charm and sent his Beast-Taming Ring flying toward her.

• After parting with Lupin, Gerald contacted Nagini through the Beast-Taming Ring, and she timidly called him “Master.”

Gerald returned to Nameless Town, reassured Nagini that he would help restore her human form, and practiced Parseltongue breathing techniques at home. Pearl then produced a sophisticated runic disc that Gerald suspected Chris Horton had stolen from Paracelsus's Laboratory, possibly the object Helena had sought.

• Pearl pulled a runic disc from her pouch, and Gerald sensed that it was a sophisticated Alchemical Device.
• Gerald suspected Chris Horton had taken the disc from Paracelsus's Laboratory and wondered whether it was what Helena had been seeking.

Gerald entered the disk’s mental space and met Paracelsus, who tried to persuade him to learn necromancy. Gerald recognized that Paracelsus intended to possess him and attacked the ancient soul with lightning, leaving Paracelsus shocked by the power.

• Gerald touched the disk’s energy core with his divine sense and entered a mental space where he met Paracelsus.
• Paracelsus explained necromancy and offered to pass on his research, but Gerald refused to learn it.
• Paracelsus flew into a rage, transformed into a monstrous torrent of remnant souls, and lunged at Gerald.
• Gerald used Finger-Tip Thunder to dissolve the attacking souls, and Paracelsus cried out in terror and asked who Gerald was.

Gerald destroyed Paracelsus's remnant soul, recovered his necromancy research, and realized the Star-Gazing Disc needed an energy core. After visiting his family and discussing a possible foreign-trade venture with Uncle Jack, Gerald returned to Hogsmeade with Lupin.

• Lupin warned Gerald to ask Hagrid about caring for the Thunderbird Egg before Professor McGonagall found out.
• Gerald got stuck outside Gryffindor Tower because he did not know the new password, prompting him to consider inventing a magical messaging device.
• Charlie gave the Fat Lady the password, letting Gerald enter the common room, where Fred, George, and Lee welcomed him back.
• Gerald took Fred, George, Kenneth, and Lee to the dormitory and revealed the Thunderbird Egg.
• Kenneth recognized the egg, and Lee exclaimed that it was an incredible pet.

Gerald brewed a Voice-Changing Potion and began learning Parseltongue before asking Hagrid to help hatch and raise his Thunderbird egg. Hagrid agreed to care for the egg in the Forbidden Forest, while Gerald would provide its weekly electrical stimulation.

• Gerald recorded Paracelsus's Voice-Changing Potion recipe and planned to brew it in the Room of Requirement.

• Hagrid arranged to regulate the egg's temperature and humidity and provide the chick's first live meal, while Gerald offered to handle the electrical stimulation.

Gerald searched for a more powerful offensive spell and broke into the Potions classroom to find the Half-Blood Prince’s old textbook. He discovered Snape’s notes on Sectumsempra and prepared to try learning it.

• Gerald left the Thunderbird Egg with Hagrid, who asked him to visit once a week and said he would tell him when it was close to hatching.
• Back in the Gryffindor Common Room, Gerald considered how to obtain a lethal spell, since he could not cast the Unforgivable Curses or ask Lupin to teach them.
• After Lee Jordan mentioned Snape and hanging students upside down, Gerald realized he could search the Potions classroom for useful dark spells.
• Gerald arrived at the locked Potions classroom before dawn, opened it with Alohomora, and found an old Advanced Potions textbook belonging to the Half-Blood Prince.
• Gerald read Snape’s notes about Sectumsempra and concluded that the original instructions might let him learn the spell.

Gerald tested Sectumsempra and tried to understand what powered Dark Magic, deciding to ask Professor Flitwick about its principles. Snape unexpectedly asked Gerald how he had made his Foundation-Stabilizing Liquid, leaving them both stunned.

• Snape entered the Potions Classroom and found Gerald studying Advanced Potions.
• Snape asked Gerald how he had made his Foundation-Stabilizing Liquid, surprising them both.

• Vivian said she planned to ask her grandfather to replace Professor Winslet next term, shocking Flitwick and the others.

Gerald learned that casting dark magic required the right emotions and considered using his ambition to make Sectumsempra more reliable. He also imagined repairing the damage dark magic caused to his soul, then left with his friends for dinner and arranged to meet Vivian at the library.

• Flitwick explained that counter-dark magic could stop, neutralize, or reverse dark magic, but warned that studying it carried risks.

• Gerald, Fred, George, Vivian, and Roger headed to the Great Hall for dinner.
