Return to the Under Realms with new battle maps featuring curious caverns and underground outposts.
This pack includes 5 large cave systems with many areas to explore and hazards to overcome.
- Cavern Outpost: A fortified settlement lies between a chasm and a stream.
- Column Cavern: Precarious walkways connect a central column to the cavern walls.
- Crystal Cavern: Luminous crystals are mined from the edges of a bottomless pit.
- Duergar Temple: A river ravine protects a hidden stronghold of the gray dwarves.
- Fungoid Cavern: Multiple caves abound with glowing mushrooms and pools of slime.
Each 40 x 30 map has multiple variations with options for lighting effects and grids. The map pack is available with Dynamic Lighting ready to import into your Roll20 game, or as a download so you can use the maps in any VTT.

Cavern Outpost Map
This fortified outpost guards a bridge over a deep chasm. Featuring several buildings, a market, and a dock on the underground stream.
What Underdark species occupies the outpost? That’s for you to decide!

Column Cavern
A massive column in the center of this cavern is ringed by a walkway and connected to other caves by precarious bridges and ropes.
A dangerous setting for combat with flying creatures. Be careful. It’s a long way down!

Crystal Cavern
A mining crane is suspended above a bottomless pit where glowing crystals are harvested.
What treasures can be found in these caves? And what creatures protect it?

Duergar Temple
A bridge over a river ravine leads to the main entrance of this stronghold. But there’s also a secret door into the temple.
The grey dwarves occupied this map in my own campaign, but feel free to add your own bad guys! Perhaps drow or mind flayers?

Fungoid Cavern
Fungoids… myconids… whatever you call mushroom folk… they live in this cave system, cultivating and harvesting ‘shrooms.
Beware the pools of slime and hallucinogenic spores!
