Oh so this thread isn't dead yet?
In that case, I'd guess that Hakim is cold, and this new acolyte is light. Someone mentioned that Hakim is supposed to be a judge -- I think this would fit better with cold than with light. A judge is focused on evaluating the here and now, not in looking to the past or future. His spectacles and "scholarly" look give him the appearance of someone who prefers distance and rationality in making decisions, and I think a cold judge would be fitting indeed for the game's narrative.
Zackirus mentioned that the unknown, shall we call him, looks a bit like a politician of some sort. I think that if he is supposed to be some kind of high-ranking governor, it would make sense for him to be light. Regardless of what people may -- justifiably -- say about politicians being corrupt and only in it for themselves, by definition, they have to look towards the future. Some look farther than others, but all have to plan ahead and think about the future consequences of their actions. So I think light fits this mystery man better than cold.
