Intermediate SeriesI1 - I14

The Intermediate series of modules for Advanced Dungeons & Dragons.  Module I1 was used as the tournament module at Origins 1980, while I11 was used at GenCon 1984.

I1 Dwellers of the Forbidden City was originally earmarked for code S4 (later assigned to the re-written Lost Caverns of Tsojcanth), before TSR decided to begin the Intermediate module series. Thanks to John Proctor for this info.

Modules I3 - I5 are referred to as the Desert of Desolation Series, and are covered on their own page.  The three were later combined into supermodule I3-5 Desert of Desolation.

Modules I6 and I10 are the Ravenloft modules, modeled after the Dracula theme.  The popularity of these modules prompted TSR to wheel out an entire Ravenloft campaign setting for 2nd Edition AD&D rules (and to subsequently re-release I6 Ravenloft as Ravenloft: 25th Anniversary (available only to RPGA members; follow the link to that page).

I6 Ravenloft comes with a double cover (module booklet nested inside two covers of maps). Thanks to Eric Pass for this info.  While not credited in the module text, the signature "David Sutherland III" can be seen in the bottom left corner of each of the maps.  The preliminary draft of the module was originally titled Vampyr, and was planned to be released by author Tracy Hickman's company Daystar West -- though publication rights were picked up by TSR before this could occur.  See more info on Vampyr on our Ongoing Research page.

I11 Needle was originally used as a three-part tournament module at GenCon 1984, then subsequently published as a three-part adventure in Polyhedron issues #24, #25, and #26.  The compiled, publicly-sold version comes with a double cover (module booklet nested inside one cover of maps and one cover of pre-gen characters). Thanks to Eric Pass for this info.

I12 Egg of the Phoenix is a compilation (and slightly slimmed-down version) of modules R1 - R4.  A plot was dreamed up to tie these modules together in I12, but it doesn't really work.  Some of the characters from this module were eventually incorporated into the Forgotten Realms via module FR5 Savage Frontier Thanks to Michele Toscan for this info.

Modules I13 and I14 are series of short adventures (I14 could almost be called "Adventure Pack 2").  I14 also contains BattleSystem-compatible scenarios.

Only modules I1, I2, and I6 have distinguishable printings.

I1 Dwellers of the Forbidden City

I2 Tomb of the Lizard King

I6 Ravenloft

Modules I7 and later had smaller print runs than their earlier brethren (due to TSR's approaching switch to the 2nd Edition rule set).  This is especially true for module I14, one of the last to be produced for the 1st Edition.

Due to their popularity, the Ravenloft modules tend to command higher-than-average prices.  I6 Ravenloft (25th Anniversary Edition) was only available in the Silver Anniversary Collector's Edition, and was not shrinkwrapped; the values listed below are for the module sold separately -- only accomplished by breaking apart a set....

Module I12 commands high prices, too, perhaps due to the trivia that it's a compilation of the very rare R-series modules.  It's also quite a bit rarer than others in the I-series.

The following represents The Acaeum's current valuation of these items, dependent upon condition (multiply by 3x-10x if shrinkwrap is present).  Values are updated at the beginning of the month, provided there were new public sales.  Click the titles to view active eBay auctions!
