Ivid the Undying

A module in Dungeons & Dragons is an adventure published by TSR, the term is usually applied to adventures published for all Dungeons & Dragons games before 3rd Edition. For 3rd Edition and beyond new publisher Wizards of the Coast uses the term adventure. For a list of published 3rd and 4th Edition Adventures see List of Dungeons & Dragons adventures. For description and history of Adventures/Modules see Adventure (D&D). Adventures for various campaign settings are listed in different articles, including Forgotten Realms, Dragonlance, Greyhawk, Mystara, Kara-Tur, Spelljammer, Ravenloft, Al-Qadim, Dark Sun, Planescape, Birthright, and Eberron.

The modules listed here are in three separate lists of official TSR Dungeons & Dragons modules only. The coded modules (1992–1995) are listed by module code. Modules made after the code system was dropped (1993–2000) are displayed in alphabetical order. Note: There is considerable overlap caused by the transition period and early pre-advertising for some modules.

Module codes in brackets indicate implied codes either by earlier advertising or place in a series; these modules did not actually have codes printed on the cover.
