The idea of homebrewing your own open world setting is daunting.

You might think of popular open world settings that represent the pinnacle of this craft - places like Skyrim, the Continent from The Witcher, or Hyrule from Breath of the Wild. Open world settings like those take large teams of people thousands of hours to create. How can we possibly do it ourselves?

The answer is to start small.

In this newsletter, we will use procedures (ie. step-by-step instructions) from an RPG called Mausritter, and sprinkle in our own random tables with a Winter Solstice theme, to rapidly generate a small open world setting you can run adventures in immediately.

Even if you don't want to run an open-world game, you'll find that following these procedures is a great way to generate your own D&D campaign ideas.

  9. Random Tables for Winter Solstice


You will need a few basic materials to follow along:

  1. The hexcrawl template from Mausritter.com OR any hex-grid paper with hexes large enough to sketch in.
  2. Some paper, a journal, or LegendKeeper to write notes in.
  3. A pencil.
  4. Some dice. A d20 and a couple d6's will do nicely.

Wait, what's a Hexcrawl?

You can think of hexcrawls as a gridded map that's designed for exploring a world, rather than running a combat encounter.

Hexcrawls usually involve travel mechanics that provide the GM with rules around how the party can explore the space. But the goal of this newsletter is to create a world - not learn new game mechanics. You don't need to learn new rules to make good use of a hex map. At minimum, you still get a nice map with a convenient grid for figuring out distances.

If you are interested in learning more about the travel mechanics, and other game systems that usually come along with hexcrawls, I recommend you read the 5e hexcrawl article on The Alexandrian.

Part 1: Fill the hexes

In Part 1, we need to turn blank hexes into a map filled with interesting places to explore. To do this we will:

  1. Number the grid
  2. Place a friendly settlement in the centre
  3. Fill the rest of the hexes with one-line descriptions
  4. Draw the map

1a: Number the grid

If you are using the template from Mausritter.com, this is already done for you! The center hex is numbered 1, then the numbers spiral outwards from there.

If you are using blank hex paper, you need to add some numbers. These numbers provide a set of hex keys you can use to refer to what each hex contains. You can number the grid any way you want - all that matters is that each hex has a unique number.

For the purposes of this walkthrough, I recommend copying the approach from Mausritter:

  1. Choose a center hex and number it 1.
  2. Move up 1 hex and number it 2. Add the next number in a clockwise direction around the center.
  3. Move up to the next circle and repeat step 2.
  4. Stop when you've numbered 19 hexes.

Here is an example of how this ends up looking. You might want to make the numbers smaller and place them in corners. We'll need to room to draw stuff!

1b: Place a friendly settlement in the centre

Generate a friendly settlement using your favorite random generator, random tables, or the settlement tables at the end of this newsletter for inspiration. This place will be a hub for the players to begin their adventure in, and return to for rest and recuperation.

The key to success is to keep it brief. Resist the urge to develop a long backstory for the settlement. All you need are a few bullet points. The rest of the story will develop through actual play!

Place this settlement in the center hex (Hex 1) by writing its name next to the hex key in your notebook. At this point, we aren't drawing anything.

1c: Fill the rest of the hexes with one-line descriptions

Write a one-line description for each empty hex. You can use the hex contents tables at the end of this newsletter for inspiration.

Once again, its important to keep it brief. The world will be developed through actual play.

For each hex on your map, roll, choose, or invent:

  • Terrain type (open countryside, forest, river, mountains, town)
  • Landmark
  • An interesting detail for that landmark
  • A name for that area (optional)

1d: Draw the map

Now that we have a numbered list of each hex's contents, we can draw! You don't need to be good at drawing to do this. Even basic symbols and sketches make the world seem more real for you and your players.

A few tips for drawing:

  • Don't worry how good you are at drawing. Have fun with it!
  • The edges of the hexes are great for adding rivers, roads, or mountain ranges.
  • Use simple representations of things. Use icons and symbols.

Part 2: Create Factions

Mausritter notes that adding Factions is optional, but in my experience it's an essential step. Even two factions will make the world feel alive, and make it easier to generate interesting stories.

Come up with 2 - 3 factions and add them to your notes. For each faction, roll, choose, or invent:

  • A name
  • 1 - 2 goals
  • 1 - 3 advantages they possess (eg. resources, special skills, knowledge)

Once again, try to keep it brief. Bullet points are fine. You can use the faction tables at the bottom of this newsletter for inspiration.

Part 3: Add adventure sites

You already know adventure sites by another name: Dungeons. These are the dangerous places your players delve to find treasure or accomplish their goals.

Creating a great dungeon is a deep topic in itself. For the sake of brevity, we will only generate some high-level ideas in this newsletter. If you have time to go deeper, we recommend reading the full instructions in Mausritter (p.34-41), watching episode 2 of Running the Game by Matt Colville, or learning about the 5-room dungeon method.

Pick 2 - 4 of the landmarks on your map and mark them as adventure sites. Spread them out so that the players have to criss-cross the map to find them all.

For each site, roll, choose, or invent:

  • A theme
  • 2 factions
  • A reward (eg. treasure, knowledge, achievement)

You can use the adventure site tables at the bottom of this newsletter for inspiration.

Part 4: Seed rumors

Create a table of d6 rumors.

As the players explore adventure sites or rest in settlements, use this table to give hints of other locations and of the activities of your factions.

  • Entries 1-3 should be true
  • Entries 4-5 should partially true
  • Entry 6 should be false

Part 5: Create encounter table

Based on the factions you’ve chosen and other inhabitants of the area, create a table of d6 encounters.

Make sure to jot down an idea of what each group is doing when the players encounter them.

You can lean on your favorite monster manual or a random generator to help. You can use the encounter tables at the bottom of this newsletter for inspiration.

Explore your world!

You should now have a small open world filled with ideas, landmarks, factions, and potential adventures. Simple procedures from games like Mausritter, combined with a few random tables, can produce great results in a short amount of time.

We hope you can use the world you've just created for something fun. Feel free to share your creation with us on our Discord server or Twitter.

Happy holidays from all of us at LegendKeeper!
