B10 Night's Dark Terror: Expert Rules Behind a B-Series Code
Editorial date: ยท TSR Archive
B10 specifies Expert rules and levels 2-4. Check the maps, counters and pull-out material before trusting a used copy or its headline page count.
The B in B10 is a poor substitute for reading the rules statement. Night's Dark Terror, TSR 9149, explicitly advertises Expert D&D play for characters of levels 2-4. Its wilderness journey also comes with enough loose material that a surviving booklet is only the beginning of an inventory check.
Why an Expert adventure carries this code
The 1986 publisher description presents a wilderness mini-campaign in Karameikos, with the Dymrak Forest and Kelven among its geographical anchors. The design is credited to Jim Bambra, Graeme Morris and Phil Gallagher in Wayne's Books' photographed-copy account. That account also discusses the B/X1 designation and the bridge between Basic and Expert play. Those details explain more than treating every B-series adventure as an interchangeable first-level dungeon.
For preparation, follow B10's own level and rules guidance. The code can help locate a catalog entry, but it cannot determine the wilderness procedures you will need. The related X1 printing comparison concerns a different wilderness introduction. It is not an inventory for B10.
Check loose pieces before resolving the page total
| Evidence | What it establishes | What to check |
|---|---|---|
| Publisher brief | Two double-panel covers, a double-sided fold-out map and 120 die-cut counters | Both covers and both map faces. Loose counters may no longer be on their sheet. |
| Archive format field | A 56-page book is listed | Record the actual pagination and any separately numbered material. |
| Publisher brief and Wayne's Books | A 64-page extent is described; Wayne photographs central pull-out material | Check for the pull-outs rather than assuming the text booklet is complete. |
The archive's 56-page field and the 64-page description do not by themselves establish two printings. Wayne's account identifies eight pages of separately numbered pull-out material in the center. That is a relevant lead when inspecting a copy, but this article has not collated every leaf of every printing. Keep the conflicting descriptions attached to their sources instead of inventing a missing eight-page adventure section.
Original cartography and later player adaptations
Wayne photographs a poster map with Sukiskyn on one side and multiple location maps on the other. Covers carry additional cartography, so finding the poster does not finish the map check. His captions are evidence about the pictured copy, not a guarantee about an unseen sale lot.
The Atlas of Mystara's Eastern Karameikos page identifies Geoff Wingate's original inside-cover map and provides a later cartographic treatment. Its January 2025 update explicitly calls the player version an adaptation with DM information removed. Label that version as a modern aid if you use it. It is not an original B10 player handout.
Prepare a location list that tells you where each map lives: cover, poster or booklet. Keep the original referee information private, and test any player-facing crop before the session. The cover shown above identifies B10. It is not a photograph certifying a complete set.
