This is the most comprehensive guide to the Cthulhu Mythos ever written for 5e fantasy. This eldritch tome, ripped from the (in)sane mind of the father of Cthulhu gaming Sandy Petersen, features over 400 pages of full color madness. Each book contains over 100 illustrated monster stat blocks for 5e with 26 stat blocks for Great Old Ones and Outer Gods. Beautifully illustrated by Kent Hamilton and Helge Balzer, these sights were not for mortal eyes to behold. This book contains absolutely everything you will need to add the mythosto your 5e adventure.
