This book covers a large range of topics, including but not limited to: depth vs breadth worldbuilding style, the design of natural laws for universes, geographical features, flora and fauna, materials, settings and genres, in-universe art and architecture, relationships between characters and civilizations, cultural traditions, governmental systems, currency and trade, guides on naming various features of a world, constructed languages, and how to receive and handle feedback as a creator. The book contains judicious examples from all types of media, and a chapter showing the results of my worldbuilding in relation to the book's content.

For authorship, explanations are given in the context of a creator looking to build a world of fiction for any medium. It explores how the environments they create can improve their ability to drive a narrative, write compelling plots, and characters that interact with that world. The book is written with an educational slant, and gives a lot of technical information about why things in our world are the way they are, and how best to apply the research you do to inspire new creations.
