The Assassin Order
The Assassins are the anti-heroes and main protagonists of the series, based on the real-world Assassins. The Assassin Order, whose various sects have been known, at various times, as the Brotherhood; Liberalis Circulum (Circle of Liberals), during classical Roman times;[1] the Hashshashin (users of Hashish[2]), during the High Middle Ages, and more, are an multiethnic, multireligious, and multinational organized order of assassins. The Assassins have existed, if not as an organized order, since the dawn of ancient history, throughout the Roman Antiquity, the Middle Ages, the Renaissance, the Industrial Revolution and into the 21st century. The Assassins provide swift justice to those who believe they are above the laws of nature and society, and believed that they fought on the behalf of those who did not possess the abilities, resources, or knowledge to speak out against those who abused their power. However, in order to ascertain which death might best assist the Assassins' goals, extensive political knowledge was required for target selection. Thus, the Assassins endeavored to remain in tune with the ever-changing politics surrounding them. Branded as 'outcasts', the Assassins were mostly feared by the general populace, due to their terrifying reputation for taking life in public before many witnesses, as their primary method of ensuring peace — so as to bring fear into the hearts of those who might abuse their power or corrupt the innocent — before vanishing into the crowd without a trace. They are the sworn enemies of the Templars', against whom they fought a continuous, recondite war, throughout the entirety of recorded human history. Whereas the Templars' sought the power to save humanity from itself by controlling free will, the Assassin Order fought to ensure the survival of libertarianism and individualism, as it allowed for the progression of new ideas and the growth of individuality. The Templar's are convinced that people must be conditioned, controlled, led, coerced, regulated, or nudged to do the right thing; the "right thing" being determined by The Templar’s idea of truth and imposed by force on others for the good of society. The Assassins' fundamentally disagree with The Templar's philosophy of "social conditioning"; they believe this only causes people to live a life where they are sheltered or protected from the consequences of their actions, and therefore never learned how to be better—to live up to their own potential. From the Assassin's perspective, the solution is not to impose rules based on subjective reality, but to allow natural law to take its course; that responsibility and self-control earned through experience are the best teachers.
