I'll introduce Chrisopher's character later in the scene, for his impressive performance.<br/><br/>My idea for his origins are that he was a Rating in the engine room (Plasma Coil Replacer, 2nd Class) whose job required him to wear power armor, and who got sorted into the elite team that took the bridge of the<em>Valence Pyre</em>.  He didn't get to lead the assault, but he was probably allowed to take point, and did MUCH better than the guy usually given the heavy bolter does.  (90% of the time, the heavy bolter given to a Rogue Trader boarding crew is used only to designate which guy will be used as cannon fodder)
