Zubair is a fake name you have adorned yourself with. Being a female is hard, especially in a testosterone filled Creed. In order to keep your secret, you've taken up a deal with the Rafik in Acre, however what if Altair had discovered this deal? Upon discovering your deal, you end up in a struggle, and making a deal with the infamous Master Assassin turned Novice, and end up working with him as he earns back his ranks to Master Assassin. If you don't work with him and help him- the looming threat of your true female gender being revealed to the brotherhood is put over your head. Because of this, you've come to realize that 'Zubair' is one of the biggest tasks you've ever taken since joining the Creed.
