Fro the publisher blurb
The Calixis Sector, while not exactly considered a Warzone, none the less has a number of Mercenary Companies or organizations operating regularly within its borders.
Mercenaries, or their representatives, can be found on most civilized worlds in the Sector, and their services are available for a price. Typically, they perform one job, or mission, but for those with the resources, Mercenaries can also be used as a standing force on a planet.
Many Mercenaries have experience from the Imperial Army, but many are also trained from the ground up by the Mercenary Companies themselves.
Mercenaries, being lone individuals or part of a large company, all work for the same cause; Imperial Thrones! This may not always be money though; sometimes they accept payment in arms and the like.
