How much of Assassins Creed is fact?

Answer 1

Although the main assassin character may not be real, it is pretty historically accurate game. A lot of things from the first game is real, including Al Mualim. The home castle in Maysaf where the headquarters were was the real headquarters for the Assassins. And all if the assasinated people in that game were real people, including Robert de Sable, who was in fact the the Grand Master of the Nights templar. With Ezio, a lot of the Assasins were real too, but werent actually Assassins. Everything that happened with the Borgia family was real and historicaly accurate (except of course the apple)
