From the publisher:
An entire subsector at your fingertips!
Subsector Sourcebook 3: Hub is meant to be a companion volume to The Hub Federation. Subsector Sourcebook 3: Hub compiles Quick Worlds 23-25 AND adds 10 more unpublished worlds to challenge and entertain your characters.
The Hub subsector is a group of independent worlds which surround The Hub Federation. Each world comes complete with detailed information concerning the system and the planet itself, yet leaves the Referee plenty of room to use these worlds as he/she sees fit.
Each world has a full color map of the world and its system.
Made with the busy Referee in mind, this book's adventure hooks can provide the spark for multiple adventures. You can use Hub as an expansion of the history and setting Gypsy Knights Games has been outlining. Or you can use Hub as a subsector to expand your existing campaign! Add it to Subsector Sourcebook 1: Cascadia and Subsector Sourcebook 2: Franklin to use as part of your own sector! Or simply use this book as a handy central source for 13 Quick Worlds to use individually as you see fit!
