I'm a bit late, but I wanted to chip in my two cents.
i'm curious where the gold versus silver divide in factions came from. I was under the distinct impression that the "Protoss" Farang (high elves?) were one faction, while the other faction was heretofore unseen in action - before this week, at least - the "Illithid" Farang (drow?) - which may be the same as the "silver" that's been mentioned before. Think High templar vs dark templar Protoss.
EDIT: I retract the assertion that the "Illithid" are Farang, pretty sure they're githyanki, wearing the mask of their ancient oppressors. I got caught up in the idea that the elves ARE illithid (having just read about the Gith), and had come to reclaim their former slaves (reflecting D&D canon). May still be true, but the People / Others dichotomy seems likely to be both branches of Gith. If the elves are in fact illithid, both ought to fight them, perhaps Inanna will end up helping our heroes rally a resistance alliance.
I got the impression that the farang (Protoss/golden/high?) that self-destructed/blasted the artifact in the jungle was hunting down an opposition member, i.e. the same faction as the one in the crystal (silver/drow?) that granted boons to Azriel, Berg, and JBG.
As to the prisoner in the oubliette - I recall Adam referring to the prisoner as either an objector or a traitor in one of the more recent GM prep episodes (referring to the reason for his imprisonment); I thought he might be a Farang who switched sides.
I'm curious about the word "Farang;" the party encountered mogwai which were really just goblins for all intents and purposes. I believe mogwai is Chinese for gremlin/goblin. I'm curious whether there is an elvish or Farang equivalent in South Asian mythology from which the name is drawn.
It just occurred to me that Azriel, who likewise had the "Passenger," and gets to keep his memories when he dies IIRC, has now returned to heaven. I suspect this may have substantial consequences if he is able to alert heaven to the presence of the Farang or, alternately, if the Passenger had its claws in him firmly enough to have tagged along with his more-highly-conserved soul.
