How does Assassins Creed end

Well, you have to travel back to Masyaf, then everyone is brain washed because of
Al Mualim. Then you make your way up to his palace and then he brings back all your assassination tagets back to life and they fight you. Then when they are dead you have to chase Al Mualim around the courtyard, then you kill him afterward.Then all of the assassin's engage in an ultimate sex show.
