Tom Riddle was a notable practitioner of this branch of dark magic, having created an army of Inferi during the First Wizarding War, mainly from the corpses of people he had murdered. Possibly his largest army of Inferi inhabited the cave where he hid Salazar Slytherin's Locket, to protect it from potential intruders. He further grew his army of the undead during the Second Wizarding War, which often created thick grey mists in the areas they occupied.
Behind the scenes
- Albus Dumbledore mentions in his notes on Beedle the Bard that Necromancy is "a branch of magic that has never worked". Assuming the original goal of Necromancy was to bring people back from the dead, this is mostly true: whilst it is possible to create Inferi, these are mindless creatures with no soul or intelligence, despite possessing human corpses and hence are not truly "raised" persons.
- If the Resurrection Stone was truly created by Cadmus Peverell rather than given to him by Death himself, it could be seen as a work of Necromancy, since it too was created with the purpose of bringing back the dead, albeit in a completely different way.
