Enter the infamous ruins of Castle Greyhawk, the most formidable and expansive dungeon on Oerth. Its mazes and catacombs have drawn hundreds of adventurers from around the Flanaess. They are intrigued by tales of its riches, undaunted by its reputation for death in countless unspeakable ways. Getting there is no trick-it's a well-traveled path. The trick is getting in and out again with your own hide intact!
Try your hand at the busiest dungeon ever created. There are more than two dozen levels of horror and treasures. Run into brutal foes and gain uncountable wealth-nearly 1,000 separate room descriptions in all!
Greyhawk Ruins is a complete guide to the most famous dungeon in the World of Greyhawk campaign setting. All you will need is the Advanced Dungeons & Dragons 2nd edition role-playing game, nerves of steel, and the resolve to challenge the puzzles and powers the ruins have to offer!
Greyhawk Ruins is designed for five to seven characters of levels 2 to 15.
We (Wizards) recognize that some of the legacy content available on this website does not reflect the values of the Dungeons & Dragons franchise today. Some older content may reflect ethnic, racial, and gender prejudice that were commonplace in American society at that time. These depictions were wrong then and are wrong today. This content is presented as it was originally created, because to do otherwise would be the same as claiming these prejudices never existed. Dungeons & Dragons teaches that diversity is a strength, and we strive to make our D&D products as welcoming and inclusive as possible. This part of our work will never end.
