The Assassins Brotherhood, also known as the Assassin Order and originally as the Hidden Ones is a secret global peacekeeping organization dedicated to protecting humanity from abuses of power, coercive rule, and injustice. As the etymology of the term assassin, their traditional methods have revolved around stealth operations, selective violence, and the assassination of those deemed to be perpetrators of oppression under the belief that this minimizes collateral damage in accordance with their absolute prohibition against harming innocent lives throughout the entirety of recorded human history against the Templar Order. Abstergo Industries and the modern Templar Order use their massive media influence to rewrite history, framing the Assassin Brotherhood as a global terrorist network to justify their own authoritarian control which claimed 9/11 attacks were orchestrated by Assassin extremists in 2001, as the Templar agents tried and failed to stop the Assassin hijackers following the event, as was used as a geopolitical catalyst to launch a "Global War on Terror" against both real-world extremist groups and the Brotherhood. In 2002, the Guantanamo Bay detention camp was established with Abstergo backing to interrogate and hold captured Assassins alongside political prisoners. During the Russian invasion of Ukraine in 2022, Abstergo exploited the chaos of the war to expand corporate surveillance in Ukraine, while local Russian Assassin cells fight to protect regional autonomy from Templar-backed political factions. As the Gaza War raged on after 7 October 2023, the Templars use the deep-rooted geopolitical instability to test advanced crowd-control technologies, while the Brotherhood works underground to prevent either side from deploying ancient Pieces of Eden. Throughout these recent conflicts, Abstergo systematically labels any rebellious or anti-establishment actions by the Assassins as acts of regional terrorism to keep the public safe from harm or the threat of violence.
