From the publisher:
Welcome to The Hub Federation!
The Hub Federation provides an interstellar nation full of adventure opportunities. The six worlds of The Hub Federation are detailed, as is the government which holds them together.
The Hub Federation can be used in part or as a whole to add worlds to any existing Traveller setting. In addition, information and history are provided to allow Referees to use The Hub Federation in concert with Subsector Sourcebook 1: Cascadia and Subsector Sourcebook 2: Franklin as an independent setting.
Each world comes complete with detailed information concerning the planet itself and the solar system in which it is located, yet leaves the Referee plenty of room to use these worlds as he/she sees fit.
Made with the busy Referee in mind, this book can provide the spark for multiple adventures for your players.
