From the back cover: First published in 1981, B2, The Keep on the Borderlands by Gary Gygax has been played by more people than any other roleplaying adventure, providing an introduction to the hobby for hundreds of thousands of gamers. Now, almost twenty years later, the Keep has declined into a sleepy outpost settlement. The trained warriors once stationed here and the experienced adventurers who once flocked to the spot are long gone. But evil once again stirs in the fabled Caves of Chaos. Humanoids, undead, and evil minions of a dark goddess plot to destroy their enemies. Only novice adventurers who have come to try their hand at dungeon delving in this traditional training spot stand in their way. Light your torches, assemble your marching order, draw your weapons, and sharpen your wits. It's time for a new generation of heroes to take on the challenge. This 64-page book includes: A special "Advice to the DM" section for beginning Dungeon Masters, offering tips and tricks of the trade. Detailed descriptions of the Keep and its inhabitants. Wilderness encounters with a wide range of classic monsters. Room-by-room descriptions of every chamber within the Caves of Chaos.
