The Lightless Depths - High Resolution Maps

Dungeon Magazine #144 produced an adventure called "The Lightless Depths" which was a continuation of the Savage Tide adventure path.  In the story, this place is located in the Underdark below the Isle of Dread.  Using Rob Lazzaretti's art as inspiration, I added to the design and created this to give our camp...

The Coenoby

This is the place where combatants gather and prepare before their time in the Free City Arena in the Age of Worms adventure path.  It's a large area that can house up to twenty-four different groups comfortably.  The clean version of this map allows it to be used for just about anything.

Flotsam Island

This is one of the earlier overland maps that were put together for the start of a nautical D&D campaign. I thought that Flotsam Island in the Sea Princes was as good a place as any to get started on a ship. The player version of this map will allow it to be used in any campaign.

This city borders the Deliverer Barrens desert and the Ischarlin jungle in Sycharia.  It's an adaptation of a cliff city turned desert bazaar.   This city was our home base for many games before we went on our jungle expeditions.  Don't forget your insect repellant.  For high resolution maps, see the ...
