The Call of Cthulhu Keeper's Companion is an invaluable resource for GM's. New material includes advice for new keepers, a lengthy study of Mythos artifacts, a learned discussion of many occultbooks, an up-to-the-moment description of every facet of forensic medicine, a thorough revision and expansion of the game skills (including nearly two dozen new ones), and the augmented text of the Keeper's Compendium, somewhat updated--forbidden books, secret cults, alien races, and mysterious places. Additional short essays and features round out this book-more than 100,000 words! The best-selling Keeper's Compendium appeared in 1993, but has been out of print for more than two years.
