THE GALAXY IS YOURS WITH ARCHITECT OF WORLDS.

We live in a golden age in astronomy. Fifty years ago, our understanding of our own planetary system was just being upended by NASA missions. We could only guess at worlds circling other stars. Now we know of thousands of exoplanets, with hundreds more revealed every year. These discoveries have been full of surprises!

A consensus has grown from the mountain of new data. From that consensus, we’ve built new guidelines for creating fictional stars and worlds! Architect of Worlds is the result of years of research into the cutting edge of astronomy and planet formation, explained in layman’s terms, and distilled into a set of procedures for authors and game masters to design believable fictional planets.

Architect of Worlds provides a complete toolkit for designing a star system and its individual worlds, as a detailed place to visit and explore. Using dice, charts, tables, logical procedures, and high-school mathematics, it gives you everything you need to know to design plausible worlds for your interstellar setting. The design system uses standard scientific units, and is compatible with any tabletop game rules.

This book includes:

• Guidelines for creating maps of interstellar space for fictional settings

• Procedures for determining the arrangement of stars, planets, and moons in a star system

• Methods for designing the surface conditions of individual worlds

• Special cases and recommendations for a variety of unusual worlds

• How to work with real-world astronomical data when designing interstellar settings

Architect of Worlds is intended for anyone who might be interested in a distillation of 21^st century astronomy, and using the science to make their fiction or setting sing!

We dig into the up-to-date science so you don’t have to!
