War.
War never changes.
In the year 2067, following over a decade of political tension, the United States of America began to annex Canada and take their resources. The process would take another decade. Rioters protested on the streets while rebel forces waged guerrilla warfare wherever they could. American soldiers were instructed to shoot Canadian protesters on sight, forcing the rebels to be much more careful in their strategies.
Leading these rebels was a man by the name of Guy Dumont. He travelled from his home in Montreal to the coast of British Columbia, gathering followers and striking against American troopers wherever he could. Few records exist of Guy Dumont. In what photographs there are of him, his face is obscured by a hood. He called his followers the Assassins, and it was under his leadership that the Assassins were able to destroy the Alaska Pipeline in 2072. But America responded by sending even greater military force to the annexed Canada. The Assassins were ambushed and slaughtered by the superior fire-power of a strike-force lead by Captain Roger Maxson. Guy Dumont and his pregnant wife were forced to flee. Using fake identities they took shelter in Vault 119, located in the heart of Vancouver.
On October 23, 2077, the great nations of China and America scarred the face of the Earth forever in a hail of nuclear missiles.
On November 16, 2250, Vault 119 opened for the first time and cautious Vault Dwellers took their first steps into the blasted remains of the city. But they would soon learn that even after two centuries, war never changes.
