Free D&D Map Generator — Dungeons, battlemaps & regions

What is the free D&D map generator?

LoreKeeper’s Map Generator is a free D&D map maker. Name a place or describe it in a sentence, choose a dungeon, battlemap, region or city map, pick a square grid, hex grid or no grid, and in about a minute you get top-down map art with a toggleable grid at 5, 10 or 1 foot per square, a key of named locations, hazards and the history of the place. No account is needed, and the image downloads for Roll20, Foundry VTT, Owlbear Rodeo or print.

Example maps

What comes with the art: a key of named locations, hazards you can run and the history of the place. A dungeon and a regional map made with this generator.

The Cinder Vault

Dungeon · Square grid, 5 ft per square

A dwarven forge-vault half-flooded when the river broke through its east wall, now held by a cult of fire-worshippers trying to relight the great furnace.

Map key

1. 1.Ash Stair

   The only way in: a switchback stair cut into the cliff, slick with soot. Cultist lookouts watch from murder-holes above.

2. 2.Hall of Bellows

   Six giant bellows, two still working. A cultist on the far side can pump them to blast embers across the hall.

3. 3.Flooded Smelter

   Waist-deep black water over cooling slag. Difficult terrain; something large moves under the surface.

4. 4.Anvil Chapel

   The dwarves’ shrine to their forge-god, defaced with cult sigils. The altar hides a key to the vault.

5. 5.The Great Furnace

   A furnace the size of a house. The cult leader is trying to relight it with a bound fire elemental.

6. 6.Sealed Vault

   Behind a rune-locked door: the clan’s last commission, an unfinished blade that is still warm.

Hazards

• Ember blast from the bellows: DC 13 Dexterity save or take 2d6 fire damage.
• Slag pits in the smelter: a creature that falls in takes 3d6 fire damage at the start of each of its turns until it climbs out.
• Rising water: each hour, the flooded area spreads one room further west.

History

Clan Barrowmere sealed the vault after a forge accident killed their master smith. The cult believes the unfinished blade can bind a fire god, and they are half right.

The Realm of Aethelred and Beyond

Region · No grid (hex grid available for travel)

A coastal realm between the Sea of Whispers and the Endless Steppe, held together by a mountain fortress and pulled apart by the free cities in the south-east.

Map key

1. 1.The Hand of Gideon

   A walled fortress around five standing stones in the Iron Peaks. Whoever holds it holds the mountain passes.

2. 2.The Whispering Weald

   An old forest whose trees are said to repeat what is said beneath them.

3. 3.The Sunken Marshes

   Fenland on the north coast, where an older city lies under the water.

4. 4.The Free Cities Confederation

   Merchant cities on the south-east coast that pay no taxes to the fortress and want to keep it that way.

5. 5.Mushroom Jungle

   A giant fungal forest in the south, home to things that are not quite plants.

Hazards

• Mountain passes close with the first snow; crossing after that takes a DC 15 Wisdom (Survival) check per day.
• The Sunken Marshes count as difficult terrain for overland travel.

History

Aethelred was one kingdom until the Free Cities stopped paying for the fortress that protected them. The fortress has not forgiven them.

How to make a D&D map in four steps

1. Choose the kind of map. Pick Dungeon, Battlemap, Region or City. Dungeons and battlemaps are drawn for tactical play; regions and cities for travel and exploration.
2. Name or describe the place. Give it a name, a sentence, or both, e.g. “The Cinder Vault — a flooded dwarven forge overrun by fire cultists”.
3. Set the grid. Choose a square grid, hex grid or no grid, at 5 feet per square (standard), 10 feet for large areas or 1 foot for detailed scenes.
4. Forge and play. In about a minute you get the map art, a key of locations, hazards and history. Download it for your VTT or print, or save it to your world.
