"The Hashashiyyin, or in English Assassin. They were an order of Nizari Ismailis, a sect of Islam. They existed in the 12th and 13th century in modern day Israel and Syria. They believed in liberty and pluralism and hated anyone who went against it. They assassinated tyrants and corrupt men, both Christians and Muslims, they weren't biased. They, not the Crusaders, were the main threat to Saladin in the 'holy land' during the time of his invasion. Though they never did anything as grandiose as starting a plague, sacking empires, or burning cities, they worked in secret like the League of Shadows, but killed in broad daylight to warn everyone else.

Yes, this is the order that the video game series Assassin's Creed is based on. Although the game gives a fictional story, it is based off a real order.
