Arc 1Regulus at Hogwarts
Regulus entered Slytherin and used his unusual magical control and curiosity to stand out while cautiously building friendships and investigating magic. By the end, he had begun exploring plant magic and was watching Hermes after finding a suspicious map in his schoolbag.
- Walburga and Orion raised Sirius and Regulus in the Black family’s traditions, while Regulus’s remembered former life shaped his plans to gain power and avoid repeating past mistakes.
- Regulus questioned the family’s blood-purity beliefs and studied magic, while Sirius’s defiance widened the rift between the brothers and ultimately led him to Gryffindor.
- After Orion warned Regulus to conceal his unusual abilities, Regulus arrived at Hogwarts, stopped James from attacking Snape, and was sorted into Slytherin.
- Regulus established himself among Slytherin students by outmaneuvering Travers and Alphard, impressing his teachers, and helping his roommates develop their magic.
- Regulus befriended Lily, challenged Snape’s attempt to control her friendships, and used astral meditation to stabilize his Magic Guidance Cycle.
- Regulus studied how Gillyweed and Mandrakes affected living beings, then transferred Magic Power between plants and began planning further research.
- Regulus found a map of Hogwarts locations in Hermes’s schoolbag and saw Hermes return after midnight with scorch marks and a cut, so he decided to keep watching him.
