A vibrant world begins with a promise, not an encyclopedia. Before deciding how many kingdoms exist or drawing a coastline, decide what someone should feel when they enter your world.
By the end of this step, you will have a short premise that gives every future idea a direction.
Begin with fascination
Write down three things you cannot stop thinking about. They can be images, questions, relationships, places, fears, or contradictions:
- A city that migrates with the seasons
- Knights who protect monsters from people
- What happens when memories can be inherited?
Do not explain them yet. Look for the energy they share. That shared energy is more useful than a list of features.
Decide what the world is for
A world built for a novel needs pressure on particular characters. A roleplaying world needs choices and room for surprise. A world made for exploration may be driven by atmosphere, discovery, or personal curiosity.
Complete this sentence:
This is a world for [audience or purpose] who want to experience [feeling, question, or kind of story].
This is not a contract. It is a compass.
Write the premise
Combine a familiar foundation, one meaningful difference, and a source of motion:
In [kind of place], [defining truth], so [people or forces] must [ongoing struggle].
Example:
Emberwake is an archipelago carried across a dark sea by ancient living islands. As those islands begin choosing different destinations, rival harbor-cities must decide whether survival matters more than staying together.
The premise names a place, a distinctive truth, and a tension. It creates questions without answering all of them.
Build yours
- What image or question first pulled you toward this world?
- What can happen here that cannot happen anywhere else?
- What experience do you want to give a reader, player, or fellow creator?
- What is already changing when someone arrives?
- Write the premise in no more than three sentences.
Create it in Summon Worlds
Create a World and use the premise as the beginning of its description. Choose a working name if the final name has not arrived yet. A clear temporary name is better than pausing the world to search for a perfect one.
Treat generated suggestions as possibilities. Keep only the details that strengthen the promise you chose.
World checkpoint
Your premise is ready when another person can read it and ask an interesting question about what happens next. If they only ask for definitions, add tension. If it takes a page to explain, remove detail until the promise becomes visible.
Next, turn that promise into a few creative principles in Define Your World's Pillars.
