In the Dungeons & Dragons role-playing game, an adventure or module is a guide for managing player knowledge and activities within a specific scenario.
Commercially, a published adventure comes as a pre-packaged book or box set that is used exclusively by the Dungeon Master.
This scenario was later developed into the stand-alone module DA2 – Temple of the Frog for the D&D Expert set rules (TSR, 1986).
[4][5] The first stand-alone Dungeons & Dragons adventure module, Palace of the Vampire Queen, was published in 1976 by Wee Warriors.
The adventure was later re-written for the first edition Advanced Dungeons & Dragons rules and published as module S4 – The Lost Caverns of Tsojcanth (TSR, 1982).
Additional unpublished adventures were distributed at gaming conventions during this period, including Steading of the Hill Giant Chief, used as a tournament module for Origins '78.
Later in 1978, Steading of the Hill Giant Chief became the first stand-alone Dungeons & Dragons module actually produced and published by TSR.
The module code was de-emphasised in the late 1980s, which also saw the campaign setting logo become a main feature of the cover.
