The Trismegistus Club

From the PDF: The Trismegistus Club was intended to play a major role in the aborted Shiva in Silvered Glass campaign for Miskatonic River Press. This Gaslight era mystic group would have served many purposes in the campaign, from providing a reason for the investigators to meet, to offering NPC assistance and possible adventure hooks, to say nothing of the organization's role in the adventure itself.
