A "reality deviant" is a person or creature in the World of Darkness universe created by White Wolf Games Studio which does not conform to the strict paradigm of reality espoused by the Technocratic Conventions. Any creatures other than normal, unmodified humans or animals are considered to be reality deviants... such as vampires, werecreatures, mages, hedge-mages, Mummies, faeries, wraiths and Bygones. Of course, humans modified by the Technocracy are not considered to be reality deviants, unless their modifications were unauthorized and fall outside the Agenda.

The Technocratic Conventions hunt and destroy any reality deviants their members encounter.
