The Instruments of the First Will, also known as the Juno cult, is an ancient pagan cult who seemingly worship Isu beings as their almighty. Originating as a secret splinter group within the Templar Order, their primary mission is to revive their Isu deities, most notably, Juno, and allow her to rule the world.
The Rise of MonotheismEdit
Back before the rise of monotheism, there were pagan religions which worshiped the surviving Isu beings as their deities. Ever since the rise of Christianity, Judaism, and Islam, the pagan religions that worshiped the Isu as deities lost almost all of their followers, but a few remained loyal to their Isu ideology. 
World War IEdit
In 1916, The Master Spy, a Sage, was leading the Instruments of the First Will's followers in London. He had not only converted many of the Templar spies to his religion, but also many other citizens of London.
Winston Churchill had caught wind of his doings and reported to Lydia Frye. Churchill described the Master Spy's group as a fanatical, religious cult, as well as a serious threat to London, and tasked Lydia Frye to deal with the group immediately.
A war nurse, who is a member of the cult, and her associate are taking soldiers blood in "odd looking cubes" for an unknown purpose. Churchill recommends silencing her and her associate, which Lydia does. Another member, a spy, is detained by the British Military in the Tower of London. He stated making fanatic claims about the Assassin's Brotherhood, so Churchill suggested it would be in Lydia’s best interests to silence him. He eventually breaks out and tries to escape. Lydia sneaks into The Tower of London and tricks the guards into murdering him.
After ridding much of the spies strongholds and weapons, Lydia eventually tracks down the spies to their main hidden hideout. After she kill's the German Templar spies, the Master Spy appears and begins to battle her while "calling out" to his beloved. After a short fight, he is forced to escape by using a flash grenade and flees to the cult's main stronghold. At the Stronghold, the Master Spy has all of his followers burn up all of their things relating to Juno or the Isu. After catching up to the Master Spy surrounded by his followers in a Stronghold, she kills them all. Winston Churchill thanks her for this service to Britain.
Infiltrating and hacking AbstergoEdit
In operation around 2013, one of the Instruments of the First Will's primary agents was thread of Abstergo IT, John Standish, who was also a Sage. During his time at the Abstergo Entertainment office in Montreal, John distributed the collective's manifesto throughout the building via quick response codes on sticky labels. John provided the Assassins with intel through a research analyst. He also got the analyst to hack into confidential folders regarding Abstergo data regarding the Precursors and Templars.
However, Abstergo got wind of the hackings and detained all of the research team. John Standish, not wanting to expose himself, reassures Melanie Lemay, the acting head of the Sample 17 Project, that he would find the hacker whiten a week's time. Meanwhile, he gets the research analyst to go to the main servers to wipe out evidence of the hackings. His true intentions were to provide Juno, now a digital being, to provide her with the research analyst's body so as to transfer her essence into.
Juno was weak from being in the servers and was not strong enough to shift her essence into the analysts body, thus foiling John's plans and enraging him. He went insane, exposed himself as a Sage and injected a non-lethal amount of poison into the analyst. John was killed by the Abstergo security team and the analyst eventually recovered from the poisoning.
Locating the ShroudEdit
Being an Isu pagan cult, the members of the Instruments of the First Will believe that humanity should submit themselves to the First Civilization once more. Their primary purpose is the release of Juno from her imprisonment.
Unlike the Templars or the Assassins, who view the Isu as a precursor species to humanity, they view the Isu as deities to be worshiped. Their beliefs are somewhat similar to the Templars'. The only difference is that whereas the Templars seek to take over the world in a supposedly benevolent attempt to save humanity, the Instruments of First Will wish to take over the world so as to turn humanity into slaves for the First Civilization.
It is their firm belief that after their death, Juno will reward them by allowing them into The Grey, a post-mortem paradise created for her loyal followers, where they will live on happily. However, it is still unknown whether they are attempting to only resurrect Juno or other members of the First Civilization as well.
