Welcome to THAC0 . . . with Advantage! We’re two friends that have been playing D&D a long time. While we both love lots of other RPGs, D&D.

In Search of the Unknown was an adventure that came out in 1978, and for a while, it was the included adventure in the 1981 Basic Set. This adventure was a little different than other adventures that would be published, because while there was a framing device describing why the PCs would show up, and what they might find, but the adventure itself included rooms and caves without any key. There was advice for the DM to guide them toward what encounters should be placed in those empty spaces. It was meant to be a teaching tool that provided the DM with some momentum. One thing the adventure didn’t do was teach the DM how to pronounce the name of the location where it takes place, Quasqueton.
