Interesting. Does that mean that Amber Sun's main theme is Revenge and how it can turn you into that which you hate most as shown almost literally with Janus and to a lesser degree, Henderson, with Bayo being that poor smutch who gets caught in the middle and pays for it despite being the most "innocent" among them?
Actually, the main theme of Amber Sun was meant to be friendship. :D You see, Janus isn't entirely selfish when he tries to cover up his past deeds. He also does it preserve his friendship with Henderson, which he knows will be over if the truth is discovered. Is that twisted? Absolutely, but it is the way Janus functions. He has painted himself into a corner, and he blows up the house to get out. Janus and Henderson has had a special connection ever since the beginning of CM. Henderson wasn't much respected among his miner peers, but Janus saw something in him. He knew there was more to him than what meets the eye (and he is right, as Henderson proves to be a great battle commander). While they spend a lot of time apart from each other in the story, they still have a strong bond. In fact, the lesson they learned in Alzadhar (when they're not fighting invisible ravagers, that is) was how stupid it was for them to argue and split up, which is why they make up again at the end of the mission.
As a sidenote: The scene in CM09 where Quarinius reveals that the soldiers he has taken control over are Amina soldiers, is one I now wish I had written differently. In the scene, Quarinius tries to bait Janus into sending Zerg against the dolfirtd, and the fact that Janus takes that bait is a bit out of character for him, I think. Yes, he is a trained assassin, not a priest, but it would have been more plausible if Quarinius had kept lying until after the Zerg had been unleashed. Janus may have desired Quarinius' death, but not to that extent. When he goes after the survivors in AS, he does it because he has to if he wants to survive. Maybe I'll go back and change it.
Your analysis is interesting, though. I like that you can put your own reading into it. I suppose with symbolism, there really is no clear answer, and yours can be as valid as mine.
