Countdown to The Fall
All Human history is considered to be canonical in the RFI universe. This should be treated as an 'evergreen' statement; if any of the details in this timeline conflict with actual events, then those events should be considered to have happened, and the timeline either adjusted, or the conflict be accepted as propaganda or misinformation by the relevant faction.
When all else fails, fall back on, "a Sooni did it."
Considered by many to be the Golden Age of Spaceflight, this time period is looked back on with much nostalgia. Humanity had such promise and a lot going for it, many consider this the point when, with a little guidance, the mistakes of the future could have been avoided.
The tail end of the 21st century was considered a time of great turmoil. The Western Collapse in and of itself would have been considered enough, but it also saw the creation of the first world government, on top of the ashes of the greatest democracy Earth had ever seen.
This time period was considered a technological renaissance, as humanity's two worlds desperately tried to find ways to solve the problems of space travel. It was also considered one of the darkest periods in human history, as the entire thrust of our technological achievements were with the goal of waging interplanetary war.
