Parapsychologist's Handbook

This monograph examines the history, methods, and theories of parapsychology for adventures set in the 1890s, 1920s, or contemporary era. It explains how to create a parapsychologist and investigate ghosts, hauntings, poltergeists, spiritualism, mediumship, and other unexplained phenomena. Guidance covers running a ghost-hunting or psychical research campaign, including non-Mythos entities, psychic powers, scenario ideas, and a Keeper’s guide to ghosts and poltergeists. Appendices provide sinister adventure seeds, new d20 psychic feats, and a bibliography of parapsychological literature from 1882–1930.
