The Initiate is the player's own modern-day character in Assassin's Creed Syndicate: a Helix user working secretly for the Assassins. Bishop has you relive the genetic memories of Jacob and Evie Frye to find a Shroud of Eden, while you watch Shaun, Rebecca and Galina through camera drones.
While you explore Victorian London, a voice draws you to a rift in the Helix simulation. Juno sends you forward to 1916 to follow Lydia Frye's war against German spies, and through those memories the Initiate finds another Sage. Juno talks about her past and hopes you will side with her, as one Assassin did before.
Despite the Initiate's work, Violet da Costa escapes the vault with the Shroud. Bishop sends you footage showing Violet and Álvaro Gramática planning to build an Isu from scratch, and Violet speaking with Juno.
Juno
Juno is the Isu who hijacks the Initiate's Helix session in Assassin's Creed Syndicate and sends them forward to 1916 to relive Lydia Frye's memories. Through that detour she tells her own story and tries to win the Initiate over.
Winston Churchill
Winston Churchill is Lydia Frye's contact in the 1916 World War I memories. He sends her after German spies in London, arranges an anti-aircraft boat against a dirigible raid, and supplies intelligence for the hunt for the Master Spy.
Lydia Frye
Lydia Frye is Jacob Frye's granddaughter and the playable Assassin in Assassin's Creed Syndicate's World War I memories, set in London in 1916. Working for Winston Churchill, she hunts a network of German spies and their leader, the Master Spy.
Master Spy
The Master Spy is the Templar running a German spy network in London in 1916, and the final target of Lydia Frye's World War I memories in Assassin's Creed Syndicate. He also leads a small cult devoted to the Isu Juno, whom he calls his Beloved.
