I think Charles Lee is going to be the main or a very major villain in the game. He is seen in the magazine choking a young Connor, as well as the fact that he died in 1782, which be a perfect excuse for an assassination. On top of that, he was known to hate Washington, who is a friend of Connor. He was also happened to marry a Mohawk chiefs daughter during the French and Indian war. It is possible he is the cause for the village that Connor grew up in to be burned. He also happened to have a temper, he was given the name "Boiling Water" by Mohawks.
