Rosario Dawson Narrating: Civilization, is a vulnerable thing. A whim of circumstance. At any time, the smallest flap of a butterfly's wings, may set a catastrophe in motion. Harran. An entire city wiped from the map. Those left behind there, did not stand a chance. The world's greatest minds came together and found a vaccine against the Harran virus. Finally, mankind had prevailed against the disease... But, people always want more... Despite a promise to shutter it's labs, the GRE continued it's research in secrecy for military purposes. It didn't take long for a variant of THV to escape into the world once more. The Fall happened more rapidly than anyone could have predicted...

Rosario Dawson Narrating: The few who survived now live in small enclaves. The only means of contact between human distant settlements, are lone individuals brave or desperate enough to travel on their own across dangerous wastelands. They are known as Pilgrims. Somewhere on the map, one city is still standing. A city isolated from the outside world. A city with special rules.

Now - it's the last bastion of humanity. A chance for us to learn from history. And for once make the right choices.

Because every choice you make here shapes the future... Irriversibly.
