From publisher blurb:
Herein you will find 333 fleeting glimpses of the World of Oldskull … the Realms of Entropy. What wonders will you create from these enigmatic inspirations?
The realms in this book will give you enthralling and mysterious idea-shards filled with exotic locales, disturbing secrets, and haunting monster encounters which you can make your own. Each of the 333 realms is uniquely named, and includes terrain details and revelations about the most unusual and powerful monsters who dwell there.
Herein you will also find hundreds of suggested random encounters by terrain type, and a unique rumor generator. The rumor generator will intrigue your players, while simultaneously providing you with new hooks which ease the creation of wilderness locales, monster lairs, adventure plots, and treasure troves. The rumor generator is also designed to aid you in building the wilderlands' history in synchronicity with your campaign realms, and this supplement syncs with both GWG1 GAME WORLD GENERATOR and GWG2 OLDSKULL ADVENTURE GENERATOR.
