From publisher blurb:
A Sector on the Frontier.
On the far reaches of the Thousand Suns lies the Marches sector of Kvin Steloj. Consisting of twenty worlds, the sector is home to the alien species known as the Chabuli, whose territories the expanding Terrans annexed by force. In the century since, Kvin Steloj has become a vital center of colonization, commerce, and exploration—much to the chagrin of the conquered Chabuli, some of whom think the time is ripe to reclaim their worlds by any means necessary.
A Sector on the Brink.
Thousand Suns: Five Stars is a 35-page sourcebook describing the Kvin Steloj sector and its twenty worlds, as well as the alien Chabuli. Also included is a scenario set on the Chabuli homeworld that can serve either as a self-contained adventure or as the starting point for an entire campaign within this frontier sector.
