William of Montferrat
You do not free the cities as you believe, but rather damn them! And in the end, you'll have only yourself to, who speak of good intentions.

William server King Richard as Regent Lord of Acre. He spends most of his time training his men for the "coming war". However, only a few of his man have been sent to join king Richard, so a lot of people are wondering which "war" he refers to. William always demands the best of his men, and he is quick to point out flaws. He rarely praises his men.

Altaïr finds out that William despises his own son, and he was planning to turn Acre over to the Templars. That was the war he was preparing his men for.
