On the outer edges of colonized space, between the Trojan Reaches and the Reft, the Usher-Athwa sub-sector is populated by a number of loosely affiliated frontier systems. These systems operate outside of the Imperium. The Crew are based on the world Tinath, one of the more populated indipendent systems in the sector. The formerly quiet and mysterious Esseray aliens have become more hostile to colonists on Tinath recently. The Crew may discover the source of the aggression. Or they may decide to ditch the planet and go exploring.
