David, directed to the Convict: "This actually is bigger than us, man. Because if that's a skeleton down there, that means this ocean supported life. Things could be alive down there right now! Food! Air! We need this! Not just the COI, all of us! We need this! It's the first shred of real hope we've had in twenty f..."
Twenty four. Twenty four years since the Quiet Rapture, or at least since what remains of humanity had a shred of hope.
If we're assuming the movie places the Quiet Rapture in the same year as the game (357 EIC, 2349 AD), that puts the current year at 381 EIC, or 2373 AD.
Timestamp 01:06:51 reveals the current year: 386 EIC. See later reblogs for details.
Twenty four years since the Quiet Rapture... sounds right. Given the the SM-8's manual was requisitioned on April 1st, 366 EIC (timestamp 00:04:56), that puts the SM-13's second(?) voyage as happening about fifteen years after the SM-8.
Nine years to discover the moons, build at least eight hemorovers, send out at least eight voyages, probably more. Then, after the SM-8's destruction, fifteen years, five more hemorovers, six-ish more voyages (assuming that the SM-13 had one voyage before Simon's).
That slowed down significantly. Were things going well up until the SM-8's destruction? Did something change? Was the COI losing interest? Losing hope?
