Worldbuilder’s Library

Our research. Your world.


Worldbuilding is fun. But unless you want to spend a decade rewriting your setting, it best to use well-researched materials from day one.

Worldbuilder’s Library is a collection of articles, books, zines, and decks written and illustrated specifically to help fellow worldbuilders create their universes.

Created by the team of writers, worldbuilders, and designers at Double Proficiency, the Library aims to cover all ground between the natural world, magic, folklore, technology, warfare, and best adventuring practices. Whether you’re in need of magical plants, engaging encounters, or are just fighting a writer’s block, the Library has something for you.

Let yourself get inspired.
