A series of maps from Dungeon Magazine, keyed and numbered but without further room detail or contents.
From the first issue
Need a lair for your campaign villain? How about a haven for a roving band of humanoids? Well, now you have one.
We're offering something new this issue: a ready-to-use map around which you can create your own adventures! The map is intended for home campaign use. There are no encounters other than the ones you create. You decide what dwells within each chamber and what savage monsters lurk in the dungeons.
Let us know what you think of this feature and whether we should continue showcasing "Maps of Mystery" in future issues.
