Building Better RPG Maps: A Beginner DM’s Guide to Worldbuilding Through Story and Terrain

If you’ve ever sat down to run your first tabletop RPG campaign and immediately thought:

“Wait… how do I actually make a world map?”

You’re not alone.

One of the biggest hurdles for new Dungeon Masters and storytellers is figuring out where to begin. Should you draw an entire continent first? Start with one tiny village? Design the dungeon before the map? Or the map before the story?

At Monkey Llama Games, we help new and experienced storytellers tackle exactly these questions every week at Storyteller’s Circle during Storyforge Saturday at 10AM. Whether you’re building your first fantasy village, planning an epic campaign setting, or just trying to make your combat encounters more memorable, understanding how maps shape stories is one of the most valuable skills a DM can develop.

This guide will walk through practical, usable advice for building RPG maps that feel alive, support gameplay, and help players become immersed in your world.

Start Small or Build the Whole World?

There are two major approaches to RPG mapmaking:

1. The “World Map In” Approach

This method starts big.

You design:

• continents

• kingdoms

• oceans

• mountain ranges

• political borders

• ancient empires

• trade routes

Then you zoom inward toward the locations players will actually visit.

Benefits

• Creates a cohesive world with believable geography and politics

• Helps long campaigns feel interconnected

• Makes large-scale stories easier to plan

• Great for experienced DMs who love deep lore and worldbuilding

Downsides

• Can become overwhelming quickly

• Easy to spend weeks designing places players never see

• New DMs often overprepare

• Can make the world feel rigid instead of reactive

This method works best if:

• you love lore

• you enjoy mapmaking itself

• your campaign is intended to span multiple regions or nations

2. The “Small Village Out” Approach

This is usually the best option for beginner DMs.

Instead of designing the entire world, start with:

• one village

• one nearby danger

• one mystery

• one tavern

• one problem that needs solving

As players make decisions and explore, the world expands naturally.

Benefits

• Much faster to start

• Easier to improvise

• Lets player choices shape the setting

• Prevents burnout

• Keeps preparation focused on what matters immediately

Downsides

• Requires flexibility and improvisation

• Long-term lore may need adjustment later

• World cohesion must be built gradually

This method works best if:

• you’re a first-time DM

• you want to start playing quickly

• you prefer collaborative storytelling

For most new storytellers, we strongly recommend starting small and growing the world organically over time.

Players rarely remember the continent map.

They remember:

• the creepy mill outside town

• the ruined watchtower

• the merchant they accidentally insulted

• the bridge where the goblin ambush happened

Start with memorable experiences. The world grows from there.

Terrain Matters More Than You Think

One of the easiest ways to make a fantasy map feel believable is understanding how terrain naturally shapes civilization.

You do not need to be a geologist or cartographer.

You just need a few core principles.

Water Follows Elevation

Rivers flow downhill.

That means:

• mountains create rivers

• rivers carve valleys

• lakes form in low areas

• swamps form where drainage is poor

If your rivers flow naturally, your map immediately feels more believable.

Vegetation Follows Water

Forests, farms, and wildlife cluster around water sources.

Dry regions create:

• deserts

• scrublands

• sparse settlements

Wet regions create:

• forests

• fertile farmland

• dense populations

This helps determine:

• where monsters hunt

• where villages survive

• where trade routes form

People Follow Water and Food

Historically, settlements develop near:

• rivers

• coasts

• fertile land

• trade access

If a city exists somewhere dangerous or inhospitable, there should be a reason.

Maybe:

• magical resources exist there

• ancient ruins attract treasure hunters

• a fortress guards a mountain pass

• religion makes the location sacred

Exceptional places become more interesting when the exception is explained.

Your Setting Should Match Your Theme

The environment should reinforce the tone of your adventure.

If your campaign is:

• gothic horror → foggy forests, isolated villages, abandoned chapels

• political intrigue → crowded cities, noble estates, trade ports

• survival horror → frozen tundra, deserts, hostile wilderness

• heroic fantasy → ancient ruins, frontier towns, legendary landmarks

Your monsters should also fit the environment.

A dragon living in an open field with no explanation feels random.

A dragon perched atop volcanic cliffs overlooking scorched villages tells a story before combat even begins.

Good maps create narrative before a single NPC speaks.

Map First or Adventure First?

There are two powerful ways to design encounters and locations.

Neither is wrong.

Approach 1: Build a Beautiful Map First

This approach starts with inspiration.

You create:

• terrain

• landmarks

• ruins

• castles

• forests

• dungeons

Then ask:

“What kind of adventure belongs here?”

Best For

• visually creative DMs

• artists

• sandbox campaigns

• exploratory gameplay

Strengths

• highly immersive worlds

• organic discovery

• memorable environments

Weaknesses

• encounters may feel disconnected

• story pacing can become loose

• prep time increases significantly

Use this if the setting itself is the main attraction.

Approach 2: Build the Adventure First

This approach starts with gameplay goals.

You begin by asking:

• what conflict exists?

• what challenge do players face?

• what emotional experience am I creating?

Then you design a map that supports those goals.

Best For

• focused storytelling

• beginner DMs

• one-shots

• cinematic adventures

Strengths

• tighter pacing

• cleaner encounter design

• easier preparation

Weaknesses

• environments can feel artificial if overdesigned around encounters

• less exploratory freedom

Use this if your priority is delivering a specific narrative or gameplay experience.

What Every Good RPG Map Should Include

Even small maps benefit from a few critical elements.

1. A Place of Danger

Where does the threat live?

Examples:

• monster lair

• cursed ruins

• haunted woods

• enemy fortress

This gives the adventure direction.

2. The Monster’s Hunting Grounds

Monsters should affect the surrounding environment.

Ask:

• where does it feed?

• what evidence does it leave behind?

• what areas do locals avoid?

This creates foreshadowing and tension.

Tracks, missing livestock, strange weather, abandoned campsites, and damaged buildings all make the world feel reactive.

3. A Safe Place to Rest

Players need emotional contrast.

Safe spaces:

• taverns

• camps

• temples

• friendly farms

• fortified outposts

These locations create pacing and allow NPC relationships to develop.

4. Places for NPCs to Live and Work

Settlements feel believable when people have routines and purposes.

Include:

• blacksmiths

• shrines

• markets

• homes

• mills

• docks

• farms

Even tiny villages should answer:

“How do people survive here?”

5. Places for Adventure Hooks

The map should naturally generate curiosity.

Examples:

• strange lights in the swamp

• a collapsed mine

• an abandoned tower

• rumors about the woods

• an old battlefield

Good maps constantly suggest future stories.

6. Places That Make Combat Interesting

One of the biggest mistakes new DMs make is creating empty battlefields.

Static combat becomes repetitive quickly.

Add:

• elevation changes

• narrow bridges

• collapsing ruins

• hazardous terrain

• moving water

• destructible objects

• cover

• choke points

Terrain creates tactical decisions.

Combat becomes memorable when players interact with the environment instead of simply trading attacks.

Your Map Is a Storytelling Tool

A great RPG map does more than look pretty.

It:

• guides player choices

• creates emotional tone

• reinforces theme

• supports pacing

• generates encounters naturally

Players should learn about the world simply by moving through it.

That’s when a setting starts to feel alive.
