When the past is changed, the future falls.
The legends of the years before,
are the ones who help the leaders of the present soar.
One must not meddle with time,
For you must remember the creed that says...
Nothing is true, Everything is permitted.
In the year 2009, Abstergo Industries succeeded in creating a time machine by using the technology left by Those Who Came Before. Thus, they decided to send an Abstergo Agent back to the time of the American Revolution to kill the legendary Master Assassin Connor or Ratonhnhaké ton. His death would allow the Templars to rule America and ultimately the world by the year 1900. A perfect plan for making their New World Order a reality.
And so, for the sake of humanity, the Assassins sent a young but very skilful teenage girl back to the year 1770. Her mission was to become familiar with the land during the era so that when the time comes, she would be able to protect Connor from the Abstergo Agent who was due to arrive in the year 1776. She trained with the young Assassin, befriended him, fought together with him and of course, swore to protect him with her life, despite his rejections.
However, there was a change of plans...
