How do you think it will look like? In my opinion, Poland in 17 or century would be great. A country where Assassins are most powerfull, couse ther's an idea of freedom and liberties for nobility. Maybe with other part of eden. And the best year would be 1655 when Swedish wanted to rule over the entire Baltic's Sea. Or 1672, when Poland fighted against Otoman's Empire, to save catholic Europe from Muslims.
