Modules X4, X5, and X10 form the "Nomad" subseries.
Module X8 misspells the author's name on the cover (and Graeme remains unamused). It was first used as a tournament adventure at GamesFair 1981 in the UK (where it was possibly titled "Island of Death"). Thanks to Adam Shultz for this info.
Module X10 is also compatible with the AD&D BattleSystem rule set (as well as its D&D equivalent, WarMachine), and includes cardboard counters.
Modules X10 and X13 are "bridge" modules between the Expert and Companion rule sets.
The working title for X11 was "Blackheart".
Module XL1 was produced to promote a line of action figures. Interestingly, the map on the inside cover has the compass rose pointed east, instead of north; this can cause quite a bit of confusion when reading the room descriptions (thanks to Neville Ridley-Smith for this info). The series "XL" is an abbreviation of "eXpert Licensed".
Module XS2 is actually an abbreviated code for "XSOLO2"... it's a solo adventure.
| Printing Information |  |
The first three modules in this series (X1, X2, and X3) have distinguishable printings. X5 also has two "printings", differing only in the presence of a cardboard header. X1 is also the only module, aside from the "monochrome" modules, that TSR produced in the U.S. with two separate covers (reason unknown). The contents in both cases are identical, with a few exceptions as noted below.
| X1 Isle of Dread |  |
- First (1980): Blue cover, Jeff Dee artwork. ISBN on back cover bottom left. "A Wilderness Adventure for Character Levels 3-7" is printed on two lines, top of the front cover. "All Rights Reserved" is the last line of text on the front cover (repeating itself). This is the first color-covered module produced by TSR, and was included in the First print of the D&D Expert Set (it was also sold separately, i.e. shrinkwrapped, and is considerably rarer in this condition). Note: On all copies we have spotted, the module booklet is copyright 1981, and has a "9034" module code in the lower right (9034 is assigned to B2 Keep on the Borderlands). The cover, however, shows the correct copyright (1980) and code (9043). We'd like to hear from anyone who has a booklet that is copyright 1980, and if so, what module code it shows.
- Second (1981): Blue cover (though a decidedly more purplish-toned cover has been noted as well), Jeff Dee artwork. ISBN on back cover bottom left. "A Wilderness Adventure for Character Levels 3-7" is printed on one line, top of the front cover. The repeated "All Rights Reserved" (see above) has been removed. This print came bundled with the Second print of the D&D Expert Set, and was also sold separately. The discrepancy mentioned above ("9034" code, 1981 copyright) is sometimes present with this print as well. (Thanks to Matthew Foster, Curt Gould, Dan Harshman, John Justice, and Luca Lettieri for this info).
- Third: Blue cover, Jeff Dee artwork. ISBN and Product Number on back cover bottom left. "A Wilderness Adventure for Character Levels 3-7" is printed on one line, top of the front cover. This print came bundled with the Third print of the D&D Expert Set, and was also sold separately.
- Fourth (1983): Red cover, Tim Truman artwork. It was bundled with the Fourth and Fifth prints of the Expert Set. Front cover layout is completely rearranged, in line with the current TSR module style. Several monsters have been changed/excised, to conform with what monsters are available in the Basic and Expert sets (for instance, the three sharks in the temple were changed to crocodiles). Also, as contributor Brett Altschul writes, "there is a glaring error on the maps, specifically the outtake diagram next to the map of the first floor of the temple. The diagram is a sketch, showing how an arched passage leads under the face set in the middle of the wall of the main chamber. This printing lacks the sketch (present in the first three printings above). As a consequence, it appears that the dungeon chambers are completely inaccessible!" (thanks to Brett Altschul for this info).
| X2 Castle Amber | |
- First (1981): ISBN (only) on back cover bottom left.
- Second: ISBN back cover bottom left, Product Number back cover bottom right.
| X3 Curse of Xanathon | |
- First (1982): TSR Face logo. Text in top border ("X3 Adventure Module For Characters Levels 5-7") is in light blue ink, which doesn't contrast well with the dark blue border itself.
- Second: TSR Face logo. Text in top border is now white. Otherwise identical to First print (thanks to Michael Dann for this info).
- Third (1982+): Angled TSR logo. Text in top border is white. Booklet cover also has the new Angled TSR logo; unknown if there's any internal differences.
| X4 Master of the Desert Nomads | |
- First: Angled TSR logo.
- Second: Identical in all respects to the First print, but affixed with a 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 (thanks to Michael Deaton for this info).
| X5 Temple of Death | |
- First: Angled TSR logo.
- Second: Identical in all respects to the First print, but affixed with a 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 (thanks to Michael Dougherty for this info).

| Auction Commentary & History |
Though current auction prices do not reflect it, the Fourth (last) printing of X1 Isle of Dread, with the red cover, is substantially more rare than its earlier-print brethren.
Rarity increases with module X6 and later, due to shorter print runs (with the exception of X13 Crown of Ancient Glory, which was apparently over-printed... copies were available from the Wizards of the Coast website well into the new millennium).
X10 Red Arrow, Black Shield fetches perhaps the highest amounts of any of the X modules. It is a thicker module, and more susceptible to damage than its brethren, as well as being compatible with BattleSystem rules (typically, anything having to do with BattleSystem goes for high prices).
Of all the X-series, X12 Skarda's Mirror is perhaps the most difficult to find.
