Arc 4The Grey Mist Beneath Hogwarts
Regulus investigated Hermes’s curse and uncovered Daren McNeil’s attempt to open a sealed chamber beneath the Astronomy Tower. The Grey Mist escaped and trapped Regulus as Avery and Alex fled to find help, while Regulus’s Patronus appeared.
- Regulus explored Borgin and Burkes with Lucretius, heard Old Bok’s offer of dangerous artifacts in exchange for Black family support, and later witnessed Aurors arrest Finn in Hogsmeade.
- Regulus visited the injured Hermes and sensed that a curse was consuming his magic, then found a map pointing to a protected entrance beneath the Astronomy Tower.
- Regulus led Avery and Alex to the hidden passage, found signs that Hermes and another student had entered, and decided to watch for the culprit rather than force open the sealed door.
- Regulus set Warning Charms and learned that Daren McNeil had visited Hermes before Abros Mulciber arrived, but he insisted on evidence before accusing anyone.
- Regulus, Avery, and Alex followed Daren into the passage, where Daren used a crystal of Grey Mist to open the stone gate.
- The Grey Mist shattered the barrier and spread through the passage, so Regulus urged Avery and Alex to flee while he held it back with protective and slowing spells.
- Regulus sent Avery and Alex toward safety, then raised a shield strengthened by Starry Sky Imagery and Bellatrix’s protective power as the Grey Mist battered it.
- As Regulus’s Magic Power dwindled and his shield cracked, his silver-white Starry Sky Kite Patronus appeared.
