The historical conflict between the Assassins, who fight to uphold peace and free will, and the Templars, who seek peace via control, is plotted in Assassin's Creed: Brotherhood. Desmond Miles, the main character of the series, uses the Animus device to relive the memories of his Assassin ancestor, Ezio Auditore da Firenze, to discover how to stop the 2012 catastrophe. The frame tale is set in the twenty-first century.

Coming from the bundle of the Assassins creed family , right before Brotherhood is Assassins Creed 2. 

Plot

In the wake of the events of the last game, Desmond Miles, Lucy Stillman, Rebecca Crane, and Shaun Hastings flee the Templars. The latter assaulted their refuge and set up a new base in the ruins of the Villa Auditore in Monteriggioni. Desmond uses the Animus 2.0 to carry on reliving his ancestor Ezio Auditore's genetic memories after restoring the electricity in the tunnels beneath the villa (Roger Craig Smith). His objective is to find the Apple of Eden, which could avert a tragedy expected to occur that year and is thought to be the work of the Templars.
