Carlotta Moro
Carlotta Moro is the ex-wife of Dante Moro and the widow of Marco Barbarigo. Carlotta became Marco Barabarigo's object of desire, causing Marco to plot a hit upon her husband Dante for his death, which failed. The attempt on his life, however, left Dante severely brain damaged to the extent that he was left with a mind equivalent to that of a child. Marco exploited this by tricking Dante to annul his marriage with Carlotta and therefore become his wife. Marco then enslaved Dante as his personal bodyguard.
Carlotta can be briefly seen in the Animus records video of Marco Barbarigo, also her voice is heard in the Documents section of the Animus' database, after a letter Ezio Auditore da Firenze had recovered after Dante's assassination. This letter reveals that her love for Dante never wavered, and she promised to hitch a plan for them to be reunited, which was ultimately thwarted by his death at the hands of Ezio.
Letter
My love,
I wonder if ever the day will come when these words might make sense to you once more. I am sorry for what I've done - for what you and I have both become. Though we could not be together, just knowing you were near was enough. And now, with Marco dead, I may yet find a way for us to be joined again.
But do you even remember me? Or were the wounds too grave? Do my words stir- if not your memory, then your heart? It doesn't matter what they say- I know you're still in there, somewhere.
I will find a way, my love. To remind you. To restore you...
Love always,
Carlotta
