From Publisher website:
The Sword Worlds stand at the border of the Third Imperium, a small but proud civilization descended from ancient Terran migrants. Their inhabitants have spent centuries fighting for independence - from the Imperium, from the other great empires, even from each other.
A decade ago, the Sword Worlds went to war against the Third Imperium. They lost. Today, the Sword Worlders are in search of a new destiny, in a universe where their fierce pride seems headed for an inevitable fall.
GURPS Traveller: Sword Worlds brings this unique culture to life for the player and GM. Every world in the area is described in detail, as are local history, social features, special technologies, and important people. A wealth of adventure seeds gives the GM plenty of starting points, for any campaign set in this distinctive region of the Traveller setting.
