Following the conclusion of AC Brotherhood, I wasn't sure what would be the plot of Revelations aside from what was eventually shown in trailers. Even then I was hoping it would be more like AC 2 then AC Brotherhood. In many respects my hope for a mysterious plot was answered and my wish for an interesting supporting character outside the Assassins was likewise given form in Sofia Sartor. Venetian by birth, native of Constantiople (Istanbul now), runs her own rare book shop, which was once the trading post belonging to Niccolo Polo, and the Polos like prior historical figures were friends to the Assassins. Though not all historical figures have been friends to this centuries old organization. Others were and have been allies to the Assassins' timeless enemies the Templars. So we learn more about the twilight years of Ezio Auditore and experience more of the memories belonging to his Masyaf predecessor Altair as well as learn more about former Templar Maria Thorpe who becomes the mother of Altair's sons (it finally answers indirectly why Abstergo went after certain individuals).

It wasn't just genetic memories.... it was something a lot more specific in some ways... Ezio's last journey puts into the decision of whether or not this fight is still his... can he live a life of his own instead of one in reaction to his family's heritage?

Sofia Sartor may very well hold the answer to all this... perhaps this is the most important of all revelations.
