England, our days. A high-ranking Templar and the new director of the Center for Historical Research, Simon Hathaway, makes an ambitious proposal: to apply the improved “Animus” not to the descendants of the Assassins, but... to the Templars themselves.

Perhaps the most dangerous truth will even be revealed: who is the true follower of the teaching, and who is a skillfully pretending to be a heretic... For the first time in Russian!
