That links to the final installment of their Writers Guide and has links to the other chapters. Basically they created a wiki to give fan fiction writers something to base their stories on. Timeline from our near future to 900 years later (when the game takes place), governments, military, corporations, alien cultures, everything they've figured out so far is listed there and it's a very interesting read.
