Crushed...

My name is Rosaline Auditore, and I am an Assassin. No, not little ‘a’, assassin, like a killer for hire, but big ‘A’ Assassin, as in the organization of people formed to protect the people of this world from tyrannical leaders and... otherworldly things. I come from a long line of Assassins, a direct line that we have record of all the way through Ezio Auditore da Firenze, the great Mentor of the Renaissance. We Auditores are a proud bunch, and by ‘we’, I mean me. I’m the last one. Blasted Templars killed off the rest of us. I wasn’t even sure that there were any more Assassins until I meet him...

Him. Kadar Ibn Kaliph. He’s an Assassin, as well (obviously, didn’t I already say that?). I found him in the ruins of Masyaf, the ancient Assassin citadel. He had been living there in order to guard the vault of Altair from Templar intruders. He had been living there since he was thirteen, as his family was apparently also of a proud line. Not quite as proud as us, I guess, as they didn’t keep their names, but he claims to be a member of the Al’Sayf family, who were the advisors for Altair Ibn La’ahad back in his day (I’m still skeptical. He’s a pretty good liar). Altair was Al Mualim, the Mentor, during the Crusades all the way up to Marco Polo’s age. Ezio Auditore was descended from him, meaning that i was as well. 

But back to Kadar. Not only is he an Assassin, but he’s a Sage, meaning that he has triple helix DNA; the DNA of the Precursor race. Those that came before, the ones that pretty much shaped the history of the Assassins. He has a connection to the past, shown by his heterochromic eyes. 

Altaïr: I must find and kill these people in order to regain my honor

Ezio: I must serve justice for my father and brothers and friends

Connor: I must join the Assassins to protect my people and fight for their freedom

Edward: I must find the greatest prize there is so my wife and I can live prosperously

Arno: I must join the Assassins to redeem myself for the mistakes I made in my youth
