Vienna Salvatori was sent to the planet Karnos Delta on a mission to infiltrate the human military protecting the Kreyfin compound and find out what was going on there. Not only did she successfully inveigle her way in, but by the time the soldiers had found out of her existence, she had successfully killed them. Upon entering the compound, she realised that Karnos Delta was being used to store prisoners in cages. The prisoners' faith was being stolen and sold to the rich.
The planet itself was miserable and storm ridden, and was described by Sargeant Lane as "mountains and crators as far as the eye can see". The native population, the Kreyfin, were crustacean and naturally lived several thousand feet below sea level. In order to survive the surface pressure, all Kreyfin had to wear special suits. When Vienna blasted her way into a room containing unsuited Kreyfin, she witnessed the decrease in air pressure causing them to violently explode. (AUDIO: Bad Faith)
