B2 The Keep on the Borderlands is a classic adventure module for the Advanced Dungeons & Dragons (AD&D) role-playing game. The module is set in the fictional world of Greyhawk and focuses on a keep situated on the frontier between civilization and wilderness. Players take on the roles of adventurers who arrive at the keep and are tasked with exploring the nearby Caves of Chaos, a system of interconnected caves inhabited by various factions of monsters. The goal is to eliminate the threat posed by these creatures and bring stability to the region.
The module provides a detailed map of the keep and the surrounding area, along with descriptions of the caves and the creatures that dwell within. It offers a sandbox-style experience, allowing players to choose their own paths and encounters as they navigate the dangers of the caves. The keep serves as a base of operations for adventurers and a stronghold against the dangers of the surrounding area.
The primary objective of the adventure is for the players to explore the Caves of Chaos, a network of interconnected caverns located near the keep. These caves are home to various factions of monsters, including goblins, kobolds, orcs, and more. Each faction has its own lair within the caves, creating a dynamic environment with potential for conflict and interaction between the different groups.
The players have the freedom to choose which areas of the caves to explore and which factions to engage with. They can gather information, negotiate alliances, or engage in combat as they navigate the treacherous underground complex. The module provides detailed descriptions of the caves and their inhabitants, along with guidelines for handling different encounters and challenges.
The Keep on the Borderlands is often praised for its open-ended design, providing a flexible framework for Dungeon Masters to customize and expand upon. It has become one of the most iconic and widely played adventures in the history of tabletop role-playing games.
