Black magic
Black magic is not a categorically different type of magic, but a matter of symbolism and intent—at least in the Anglo-French sphere, as the Kingdom of Italy requests extradition of a woman for black magic when her actual offense was no more than unlicensed magic. However, the effect of symbolism and intent can be substantial; one character, a Witch-Smeller, is capable of detecting its effects on the black magician and his victims.
