Are Dementors magical creatures with inherent magical powers?
Or do their powers of despair, depression, cold, and hopelessness come from their eternally soulless existence?
Do we ever see Dementors perform any kind of magic¹ in Harry Potter? Do Dementors have magic?
¹Other than the Dementor's Kiss, which I don't know whether or not is magic or pure, unadulterated evil.
