Arduin Dungeon #1: Caliban (first printing), softback adventure for Original D&D and most fantasy RPGs, by David Hargrave
“This is the first of a series of “dungeons” based on the best selling “Arduin Trilogy”. Contained within each new dungeon will be: four separate maps, eight new monsters and eight new magik treasures (all on handy pocket sized cards), a capsule history of the dungeon and other “goodies” unique to each separate release.
Note that at some point between 1979 and now, the pocket sized cards have got lost. They are NOT PRESENT in this copy. The cover has also detached as have the central pages. Apart from that, I would describe the overall condition as FAIR.
This very rare adventure was created to accompany David Hargrave’s Arduin Grimoire series, which was nominally a separate roleplaying game, but was actually mostly used as a supplement for Original D&D.
