In 1972 a group of experimenters from the Toronto Society for Psychical Research set out to see what would happen if you tried to summon a ghost in a seance, but with the total knowledge that that particular ghost - “Philip Aylesford” - never existed, was never a real, living person, and instead was an entirely fictional character, akin to a character in any other roleplaying game. What they found is that the same thing happens as if you try to summon a real ghost - indicating that it may be the case that all so-called “ghost” phenomena are in fact psychokinesis generated by the living humans who are present. Now the instructions for how to carry out that experiment are presented to you, so that you can carry out their experiment for yourself. Create your own character, develop your psychokinetic powers, and see what you can conjure up.
