In Atmosphere of Sepheris Secundus, Golenna Reach, Calixis System, Segmentum Obscurus, on the northern edge of the known galaxy.
It was clear from the tone of your master that you all were not the ideal candidates for this mission. Indeed, he seemed to hesitate as he gave you the rundown of the situation on Sepheris Secundus. There was a recent uprising that necessitated force to put down and so a platoon of Imperial Guard set down in the heart of the rebellion and silenced the mobs.

With little more room than to sit with arms and legs held tight you and the others race downwards through the rumble of the atmosphere. A small dataslate embedded in the wall of the lighter flickers a monocrome green and black screen. Quick enough, whether you like it or not, you will reach landfall...
