Mystara Solo SeriesMSOLO1 - MSOLO2

Solo modules developed for the Dungeons & Dragons Basic Set and Expert Set, respectively.

Both these were assigned the "M" module codes seemingly without much forethought.  When the D&D Master Set came out a few years later, TSR apparently decided to go ahead and re-use the M codes for its Master series modules.  To dispel this confusion, we'll refer to these modules using the MSOLO codes, even though they were never actually assigned or printed with them.

Both modules come with "magic pens" (either with a blue or yellow cap), which reveal "hidden" text blocks depending on your choice of actions.  As such, they are pretty much single-use only.  TSR attempted to solve this deficiency with their later solo module, MV1 Midnight on Dagger Alley, which uses a red-plastic "magic viewer" instead.  Interestingly, most (all?) foreign editions of the MSOLO modules also use this "magic viewer".

MSOLO1 Blizzard Pass

First:  Angled TSR logo.

Second:  Identical in all respects to the First print, but affixed with a red cardboard header on top of the module, with the D&D logo and some other advertising.  Note that without the header, this print would be indistinguishable from the First print.  Further info on header modules is here.

Current Market

Because of the included "magic pens" (attached on the side of the front cover with a piece of Velcro), and the one-use text blocks, these modules are only rarely found in unrevealed or shrinkwrapped condition.

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!
