Map of Pelestia and surrounding countries I started a three-ring binder for this. I have tabs and dividers. I am building a world. I've built little worlds before for stories, but none of them needed very much building. This one is bigger and the world plays into my story in a vital way. So I am drawing maps and naming rulers and playing around with economies and politics and religious views and weaponry and technology and many other facets. And I would like your advice: How do you build a world? Do you have any checklists that you use?
