In Search of the Unknown

The very first Dungeons & Dragons module designed for use with the 1st edition boxed Basic Set rules, coded B1. "In Search of the Unknown" was designed for a group of 1st-3rd level characters, who were tasked with exploring the Caverns of Quasqueton. A pretty standard-issue dungeon crawl, only certain details of the interior rooms were randomly determined by die roll, and blank spaces were, accordingly, provided beneath the encounter descriptions.

"In Search of the Unknown" was included with the first few printings of the boxed Basic Set (the monochromatic blue box edition). Starting in 1980, the retooled Basic Set box (the red box editions) substituted B2: The Keep on the Borderlands. Eventually, however, "In Search of the Unknown" was reprinted as part of a compilation volume of the first nine Basic D&D modules.
