- Occupation Notes
- During his long initial period of employment at Hogwarts, Slughorn taught several of the main characters in the Harry Potter story. Among his pupils were a young Severus Snape and Lily Evans, Harry's mother and one of Slughorn's favourite students, whom he repeatedly praises as "one of the brightest I ever taught...vivacious...charming...cheeky". Significantly, however, an earlier cohort of students included Tom Marvolo Riddle. On one occasion, Riddle questioned Slughorn about Horcruxes, artifacts which could act as vessels for pieces of a person's soul in order to grant immortality. Having learnt of the nature of Horcruxes, Riddle went on to perform the necessary Dark magic to create his own Horcruxes, which contributed to his formidable power in his later reign of terror under his assumed name of Lord Voldemort.
