From the back cover:
"Encounters in the Strange Lands is a complete set of 20 excitingly new and different dice tables for the 30 Sided Dice. Teaming the dice designing brilliance of the Armory and the sly humor of Bob Liddil (author of The Armory's 30 Sided Character and Other Tales,) This book is both entertaining and enhancing to any Fantasy Adventure game which employs dice."
Most of the tables in this book describe encounters and locations in "The Strange Lands," a fantasy setting created by Liddil. Also included are a system-generic adventure ("The Search for Fezeneclop's Treasure") and a short story ("Stopover at the Crying Lion"), both set in the Strange Lands.
