Weird shapes in the park? Odd rumbling noises in the basement? A lurking dread in the kitchen? Bad dreams involving strange adventures and bizarre creatures?

Identifying the lurking horrors of the Cthulhu Mythos is never an easy task, so researchers need all the help they can get—don’t leave home without the Field Guide!

Penned by Sandy Petersen, the creator of the Call of Cthulhu roleplaying game, Petersen’s Field Guide to Lovecraftian Horrors is the essential spotter’s guide for the budding and experienced preternaturalist.

Over 50 beasts of the Cthulhu Mythos are detailed and categorized with background information, size comparison charts, habitat and lifestyle notes, and much more. Each entry is accompanied by a full-colour illustration of the dreaded entity.

Petersen’s Field Guide To Lovecraftian Horrors is completely rules-free. You can use it to inspire your own Call of Cthulhu (or RuneQuest or 7th Sea!) scenarios, or the book itself can be used as an in-game prop—a tome of forbidden knowledge!
