From Introduction: The 1992 edition of Lost Souls included a chapter on mediums, those mortals who can communicate with the dead and are determined to assist the spirits of the departed. Although mediums were omitted from the online edition, the idea was resurrected by Sean McCluskey in Body and Souls, his rules for incorporating a variety of mortals into Lost Souls. The rules presented here combine the original rules for mediums, the ideas of Mr. McCluskey, and material from the unpublished Charnel Knowledge supplement. The rules are experimental. Feel free to use what works and change what doesn’t.
