Spend some time of r/worldbuiling and you will see that many posts are from new users asking how to start worldbuilding. The short answer to this is simple-however you want! But since it seems to be such a common question I decided that I would outline my worldbuilding process here for anyone who wants to start but isn’t sure how.
1. Pick a Medium
There are a lot of ways to organize your worldbuilding. For most of my projects I like to start with a nice notebook. This comes with a few limitations, it can be hard to keep topics organized and it can be hard to go back and change major details and keep everything looking neat, but if you are as fanatical about writing implements as I am then it’s a fun way to worldbuild and use your favorite pens at the same time.
Other people use OneNote, word documents, personal wikis, or services like WorldAnvil. In the end it doesn’t matter what medium you use as long as it suits your needs or preferences.
2. Have an Idea
A lot of career advice talks about having an “elevator pitch” ready and you should have the same for your setting. If you’re making a world to run a table top campaign then this pitch might come from your players. Maybe your players want to run a wizard mafia, or find an abandoned city in the far north surrounded by frozen tundra. If you’re worldbuilding for fun or for a story you plan to write you might ask yourself what would happen in a world where the industrial revolution happened a few centuries early or Rome never fell. Once you have a theme to explore or a specific scene in mind you’ll find it much easier to make a setting where those themes or scenes are possible.
3. Pick an Era
Deciding on the level of technology found in your setting is important. It establishes the tools available to your characters, the capabilities of governments, and the resources that countries are willing to go to war over. In a world where everything runs on steam coal will be a much more valuable resource than oil, but if you’re writing diesel-punk this dynamic will be reversed.
When I pick a technology level for a setting I tend to think in terms of centuries. This is just to help visualize the kind of technology and tools available in your setting and should not feel like a limitation. In the end this is your world, if you want to introduce a new technology or put a new spin on historical inventions then do it!
Easily accessible magic will drastically change the dynamics of your world, so deciding if magic is common, or if it exists at all, should happen early on. You should also consider outlining the limits of your world’s magic and whether it can be classified as “hard” or “soft” magic.
If you are considering a world in which divine intervention is a regular occurrence, this would be the time to do it.
5. Make a Map
Our culture is shaped by our environment and who we come in contact with, our economies are shaped by the resources available to us, and these along with other considerations shape the conflicts we engage in. Since you are probably not going to start from the creation of your world and move forward, you’re going to need to picture the “current” state of your world and work backwards to decide what geographic features might have contributed to its current predicament. Mountains, rivers, and oceans can form natural barriers and help explain why a certain culture has stayed relatively isolated, the positions of trade routes, harbors, and rivers will decide where your major cities go.
Scale is important to think about here. You might be tempted to create an entire world map on your first go, but you should consider how much of the world you need to show for your story. Mapping an entire world is fun, but you might find yourself biting off more than you can chew. To combat this I now only map out the region that I plan to focus on and wait to flesh out others areas until I need them.
6. Fill in the Rest
This is the part where you let your imagination run wild. Outline character bios, write the histories of obscure locations or the stories of empires. There’s not really any wrong way to do this. It’s your setting, do what you want with it.
