Chapter Summaries

Will tested how the Cruciatus Curse and Memory Charm affected a Werewolf’s Magic structure, then discovered a way to cut Magic by precisely directing an enhanced Sectumsempra. He began experimenting with the new technique, which he regarded as a blade that could cut Magic.

• Will tortured a Werewolf with the Cruciatus Curse and found that severe memory damage and a Memory Charm made its Magic structure pitted but did not break or split it.
• Will tried to target the Werewolf’s arm with the Cruciatus Curse, then forcibly twisted the spell through sheer will and amplified it with Ancient Magic.
• The Werewolf’s arm shattered, prompting Will to realize that damaging the body and soul could affect Magic directly.
• Will brought in another Werewolf and used Sectumsempra enhanced with Soul Annihilation to make small cuts along its Magic structure.
• Will became excited as the experiment revealed that Sectumsempra could act as a blade that cut Magic.

Will’s experiments on Lupin’s magic structure reached a dangerous bottleneck, so he consulted Dumbledore, who suggested that werewolf and wizard magic might be connected and need transformation rather than separation. Will realized he might be able to contain and remove the magic carrying werewolf venom, potentially cure werewolves and even create wizards.

• Will found that his experiments had badly damaged the werewolf’s magic structure and decided he needed advice about souls.
• Will met Dumbledore by the Black Lake and explained his research into changing magic through the body and soul.
• Dumbledore suggested that werewolf and wizard magic could be branches of the same structure, making transformation safer than cutting one away.
• Will recalled that Muggles infected by werewolf magic became magical beings after their transformations ended and reconsidered how werewolves differed from Veela.
• Will theorized that he could contain and remove the magic carrying werewolf venom, and that the venom’s blueprint might let him create a Werewolf Curse capable of creating wizards.

Dumbledore urged Will to approach a difficult problem by inventing a spell, then told him to gradually resume spending time with Harry while Snape taught Harry Occlumency. Harry told Will about Umbridge’s painful detention and asked for a way to fake illness, but Will refused and hinted he could instead drive Umbridge out of Hogwarts.

Will advised Harry and Hermione to expose Umbridge’s use of Dark Magic through wizarding newspapers, then received Voldemort’s urgent orders to watch Dumbledore and investigate the Lestrange family vault.

Will used an improved Werewolf Venom Curse on three werewolves during the full moon, forcing the venom magic into a localized region but leaving them only partly transformed. He planned to finish the magical surgery after returning to his proper timeline and use the result to build Faith, gathering power from Wizards and Muggles alike.

• Will decided to use the Hour-Reversal Charm and strengthen the Werewolf Venom Curse so it could isolate the venom magic within a werewolf’s body.
• During the full moon, Will cast his improved curse on three chained werewolves, forcing their venom magic to retreat and their fur to fall away.
• Will stopped short of cutting away the isolated region because he feared time would punish him for completing the work in the past.

By dawn, he had refined the procedure to leave only minor wounds, but its deeper drawbacks remained as he headed to the Headmaster's Office.

• Will tested removing werewolf magic from severed hands, fingers, and a tiny patch of flesh, finding that the magic persisted unless he damaged the corresponding magical structure.
