Arc 8The Abyss and the Return
Regulus joined Freya in confronting Abyssal Whisper and exploring the North Sea ruins, where he rejected a path that would sacrifice his selfhood and strengthened his trust in his own magic. He returned to Britain, resumed life at Hogwarts, and began probing the deeper principles behind magic and matter.
- Regulus and Freya attacked an Abyssal Whisper stronghold, and Regulus’s Diolvo and Fiendfyre destroyed the island while some of the masked wizards escaped.
- Regulus and Freya followed the Maritime Document’s coordinates beneath the sea, where a mysterious core challenged Regulus’s understanding of his magic and urged him to abandon his own path.
- Regulus rejected the core’s offer of power at the cost of his emotions and selfhood, and Orion’s five stars blazed as Bellatrix embodied his independent will.
- Joachim offered Abyssal Whisper’s knowledge and treasures for the document, but Freya and Regulus refused to reveal what they had found or make a trade.
- Regulus returned to 12 Grimmauld Place and told Orion that Grindelwald had arranged the events, while Orion considered how the Black family could navigate among Dumbledore, Voldemort, and Grindelwald.
- Regulus returned to Hogwarts, where Slughorn recognized his intuitive ancient method of brewing, Lily confronted him about not writing, and McGonagall discussed the limits of Transfiguration after he demonstrated Spatial Transfiguration.
