Spoilers for Episodes 1, 2, and 3 ahead. I thought this would also be game-ruining theories until I read
and I realized that you all were already thinking on this level. Here goes...
It appears that the biblical analogizing of characters in the Aetherlight follows an alliterative pattern. For example:
Alexander = Abraham
Selina = Sarah
Irving = Isaac
Ishaan = Ishmael (His later taking the place of Julian on the racetrack may be symbolic of Jacob's name change to Israel.)
Julian = Jacob
Edmund = Esau
Larry = Laban
Rose = Rachel
Lily = Leah
Jefferson = Joseph
Lucky = Lucifer ahem
Baron Fairrow (say his name out loud) --> with that being said, it appears that the Snowmoors are an analog for Egypt. Theory #1: Upcoming plot will likely revolve around extracting the Blessing from the Snowmoors and fighting off the Baron and his forces trying to stop the airship from leaving. A character whose name starts with M (possibly a student at the Academy Automicus?) may have a prominent role.
With that being said, some characters don't fit the alliterative pattern, and these cases are especially interesting. The first is Victoria - I think her actions peg her as Potiphar's wife, who was unnamed.
Georgia = ??? She appears to be related to Irving, so maybe a Rebekah stand-in? But that doesn't make any sense because she supports Edmund on the racetrack, and the real-life Rebekah was a supporter of Jacob. Also of note is that Hagar is missing but I think she was cut due to the "too many characters" phenomenon.
Emily = ??? My first instinct is to peg her as Pharaoh's unnamed daughter. But who is Claude?
Lloyd = ??? No idea. (He's the dealer that gets you and Julian onto the Flying L at first.) Lot? (It's possible that the Isle is an analog for Sodom and Gomorrah...)
Lukas = Lord? Theory #2: Lukas is the Great Engineer, and his mind got corroded by fog. (But this might dangerously break the analogy in a bad way, so not sure if it is true. Or he could just be playing us.) He could also be the New Testament writer Luke, but why introduce him so early? Another Lot candidate?
Scarlet Man = Savior? (But I think he is merely a stand in for Scarlet City Studios. He still strikes me as a Jesus figure of sorts.)
Anyway, I love the way all of these mysteries are placed all around us in the game as an intriguing puzzle!
Remember that this is just a theory and not anything proven from the developers - feel free to criticize my thinking. Hopefully this will be food for thought and not just chasing alpacas.
