Wildebeest Society
The Wildebeest Society was a criminal cartel who conducted various underhanded affairs for financial gain. Although the Society was made up of many members, only one Wildebeest ever operated publicly, giving the illusion that all of their crimes were being committed by a single individual.
Witches
In faerie tales, this usually refers to female wielders of magic, often depicted as ugly devourers of children. In real world mass panic, this has historically referred to both male and female wielders of supernatural powers from that religion's notion of ultimate evil. In modern popular culture, the term "witch" has fused with the notion of fairy folk and become the name for a glamorous humanoid species that wields magic as a natural attribute, often found in superhero comics and TV shows.
