Beyond the Crystal Cave is a Dungeons & Dragons module set in the World of Greyhawk campaign setting. It is unusual among Dungeons & Dragons modules in that it encourages a non-violent approach (mainly parleying and true role-playing tactics) to achieving the module's goals. It is set in an old English milieu on Sybarate Isle in the Hold of the Sea Princes.

He liked the clear layout, lucid descriptions and good maps and found it a module that tries to emphasize diplomacy and intelligence over force and is "more successful than most in achieving this aim". Cowie thought that it is possible to go through the adventure "without drawing a sword" and that the main setting, Porpherio's Garden, is "highly original and well thought out". His only criticism was that some of the denizens of the garden are too prone to random attack, but he felt that was a minor point, easily altered by the DM. Overall, according to Cowie, UK1 is a "refreshing change" which "gives the talkative sort of character a place in the limelight all too often filled by the brutish fighter or the powerful
