“Some discussion of the nature and temperament of the fairies is necessary in view of its possible bearing on their origin. J. G. Campbell tells us that in the Highlands of Scotland they were regarded as "the counterparts of mankind, but substantial and unreal, outwardly invisible." They differ from mortals in the possession of magical power, but are strangely dependent in many ways on man. They are generally considered by the folk at large as of a nature between spirits and men. "They are," says Wentz, "a distinct race between our own and that of spirits.”
