Expedition to the Barrier Peaks is a 68-page sourcebook for Advanced Dungeons & Dragons 1st edition released in February 1980.

Official synopsis[]

The Grand Duchy of Geoff has recently been plagued by a rash of unusually weird and terrible monsters of an unknown sort. This western area, particularly the mountain fastness which separates the Grand Duchy from the Dry Steppes, has long been renowned for the generation of the most fearsome beasts, and it has been shunned accordingly -- save a handful of hardy souls with exceptional abilities. Within the last few months, however, a walled town not far distant from the area, and four small fortresses as well, have been destroyed by mysterious attacks!
This adventure was the official Advanced Dungeons & Dragons Tournament scenario at Origins II. This version has been carefully revised and updated to conform to AD&D games system rules. Included herein are background information for players, statistics for a party substantially the same as that used for the tournament, DM notes, six level maps with encounter matrices, and numerous full color illustration of scenes from the adventure in order to enhance the enjoyment of participants. There are also many new and special monsters designed for this scenario, and they appear nowhere else.
For characters level 8 to 12.
