Welcome to the Worldbuilding Hub! The goal of this site is to serve as a repository of resources and articles (written by myself) to help people add physical realism to their fictional worlds and star systems – as such it is useful for any sci-fi project (be it a book, a setting, or an RPG) and is often quite educational in places.

My RPG Books
I’ve co-authored a couple of (well-received) SF RPG supplements over the years for which I did a lot of world-building. I came up with the realistic physical data and descriptions for the Katringa system in Spica Publishing’s System Book 1: Katringa, and wrote the extraterrestrial oceanography chapter in SJG’s Transhuman Space: Under Pressure (doing quite a bit of original research on how technology would work in Europa’s ocean in the process!). The Titan section of Under Pressure differs from reality since at the time of writing we hadn’t received data from Cassini about Titan’s hydrocarbon lakes, so we went with the best guess at the time (a large equatorial methane sea)!
|System Book 1: Katringa, by Constantine Thomas and Richard Hazlewood (2010). System Book 1: Katringa is the first in a series of books from Spica Publishing that describes a complete planetary system and its society, designed for use with Traveller from Mongoose Publishing (but can be used with any other science fiction RPG as well).
Katringa is a small, cold world with an exotic atmosphere located off the main trade routes. It is a former corporate mining colony run by Horizons Unlimited corporation that is gradually being allowed more independence over time, although corruption still pervades the government. The book contains a realistic planetary system designed using current astrophysical knowledge, full details of the worlds in the system (including the mineral-rich Idowa Belt, the gas giants Accra and Yendi and their moons, and Olufemi and the Outer Asteroids), a complete physical description of the planet Katringa, including a detailed breakdown of its geographical features and timekeeping system, details on Katringa’s society and important NPCs, Adventure Seeds, and detailed asteroid mining rules!
|Transhuman Space: Under Pressure, by David Morgan-Mar, Constantine Thomas and Kenneth Peters (2003). This supplement for SJG’s Transhuman Space roleplaying game (for GURPS 3e) covers the ocean environment of the 22nd Century – the teeming seas of Earth, the newly terraformed waters of Mars, the moon-spanning ocean under the ice of Europa, and the methane lakes of Titan. Ocean arcologies, mining operations and terrorist foes, and adventure and intrigue in an environment far more hostile than mere space.
This book also includes new character templates — including new parahumans, bioroids, cybershells, and uplifted animals designed for aquatic existence — and modular design rules for aquatic vehicles, compatible with the system in Transhuman Space: In The Well.
My JTAS Articles
I submitted a couple of articles to the Journal of the Traveller’s Aid Society (JTAS) in 2003 which were both published – I endeavoured to make these as realistic as possible by basing them on current (at the time) scientific knowledge, and AFAIK they’re still valid today. Note that you’ll need to have a JTAS subscription to be able to read them.
