I was kind of thinking that the guardsman is a lone survivor who just tags along, but, maybe I can fix him up so that he knows something of great use to the inquisition and is too great of a value for them to just kill... instead, maybe, he could have the emperor appear in his dreams or the inquisitions and would seem to be a vessel for the emperor for the duration of the roleplay, that sounds too great for the situation.  Maybe he could be used as a guide to different units of guardsmen or maybe even guide them to the titan, that sounds more realistic but I wouldn't know if the inquisition would need him for that.
