Assassin's Creed: Syndicate

=== Setting and characters ===
In 1868, at the tail end of the Industrial Revolution, with the Assassin Brotherhood all but eradicated in Victorian London, twins Jacob (Paul Amos) and Evie Frye (Victoria Atkin) leave Crawley for London and arrive to find a city controlled by the Templars, with both the Church and the Monarchy losing their power. Raised as Assassins to follow the Creed, Jacob and Evie aim to take back the city from Templar control by infiltrating and uniting London's criminal underworld, aided by notable figures of the era such as novelist Charles Dickens (Des McAleer); biologist Charles Darwin (Julian Richings); inventor Alexander Graham Bell (Mark Rowley); political theorist Karl Marx (Matthew Marsh); nurse Florence Nightingale (Helen Johns); Maharaja Duleep Singh (Avin Shah), the last maharajah of the Sikh Empire; Sergeant Frederick Abberline (Sam Crane) of the Metropolitan Police Service (known for his investigation of Jack the Ripper); and Queen Victoria (Ellen David). Additionally, Jacob's granddaughter, Lydia Frye (Lisa Norton), appears in a separate World War I segment, where she aids Winston Churchill (Rick Miller) in defending London against a new enemy espionage faction.

Plot

In 2015, the Helix player, now an Assassin Initiate, is again contacted by Bishop (Kate Todd) to help the Brotherhood find a Piece of Eden in London. While Rebecca Crane and Shaun Hastings infiltrate Abstergo's facility in London, the Initiate relives the memories of Jacob and Evie Frye, twin Assassins from the Victorian era.
In 1868, Evie infiltrates a lab run by David Brewster and Templar occultist Lucy Thorne (Emerald O'Hanrahan), and finds them experimenting on an Apple of Eden. Evie assassinates Brewster, learning that the Templars seek another artifact in London, and escapes from the lab after the Apple explodes. The Frye twins head to London to stop the Templars from finding this Piece of Eden, and meet fellow Assassin Henry Green (Jaz Deol). Henry informs them that the London Brotherhood has fallen, and the city is controlled by the Templars, led by Crawford Starrick (Kris Holden-Ried), a powerful figure in the city's industry and criminal underworld. Although Evie wishes to search for the Piece of Eden, Jacob convinces her to help liberate London's boroughs from Templar-run gangs. In the process, they build up their own gang, the Rooks, and make allies such as Clara O'Dea, Frederick Abberline, Alexander Graham Bell, Charles Darwin, Charles Dickens, Ned Wynert, and Edward Hodson Bayley.
During this time, Jacob, seeking to undermine Starrick's control over London society, assassinates Starrick's allies, including Dr. John Elliotson, who oversaw the production of an addictive tonic; Malcolm Milner, the owner of Starrick's omnibus company; Pearl Attaway, Starrick's cousin and owner of a rival omnibus company; Philip Twopenny, the Governor of the Bank of England who was secretly robbing it; James Brudenell, 7th Earl of Cardigan, who planned to assassinate Prime Minister Benjamin Disraeli; and gang leader Maxwell Roth, who initially supports Jacob, but later reveals himself to be a dangerous sadist.
Meanwhile, Evie looks for the Piece of Eden with Henry's help. Following clues underneath Edward Kenway's mansion, they find the key to the Shroud's vault at St Paul's Cathedral, but Thorne steals it and flees to the Tower of London. Evie infiltrates the Tower and kills Thorne, who reveals the Shroud is not there. Henry believes the vault is hidden in Buckingham Palace, and enlists Maharajah Duleep Singh's help to obtain the building's schematics; however, the Templars seize them first. Evie also corrects consequences of Jacob's assassinations, such as medicine shortages and currency inflation.
With his lieutenants dead, Starrick moves to retrieve the Shroud and eliminate Britain's heads of church and state. Jacob and Evie argue over his recklessness and her inaction, but agree to work together to stop Starrick before going their separate ways. They infiltrate a ball held at Buckingham Palace, but Starrick beats them to the vault and obtains the Shroud. With Henry's help, the Frye twins kill Starrick, before reconciling and returning the Shroud to the vault. For their deeds, Queen Victoria knights the Frye twins and Henry.
In the present, Rebecca and Shaun spy on a meeting between senior Templars Isabelle Ardant and Álvaro Gramática, who are also searching for the Shroud. They attempt to capture Ardant, but are forced to flee after being attacked by Otso Berg and Violet da Costa. After the Initiate locates the Shroud, Shaun, Rebecca and fellow Assassin Galina Voronina head to the vault, but discover that Ardant, Berg, and da Costa beat them to it. A fight ensues, in which Ardant is killed and da Costa escapes with the Shroud. Hacking Ardant's computer, the Assassins learn the Templars plan to use the Shroud to construct a living Precursor. They also discover that Juno is manipulating employees within Abstergo to sabotage the company, and has her own plans for the Shroud.

Time Anomaly

While exploring Jacob and Evie's memories, the Initiate encounters a "time anomaly" in the Animus, which causes them to relive the memories of Jacob's granddaughter, Lydia Frye. In 1914, at the outbreak of World War I, the Brotherhood removes Jacob and Evie to the countryside while Lydia's husband, a fellow Assassin, is enrolled in the British Army, leaving Lydia to defend London from German spies. In 1916, at the behest of Winston Churchill, Lydia eliminates a German spy facility in Tower Bridge. In the process, she discovers the Templars have infiltrated the Germans' spy network, and hunts them down. In exchange for her services, Churchill promises Lydia that he will ensure the enfranchisement of women after the war. Lydia eventually conquers every Templar-infested area in London, and flushes out the leader of the Templars, revealed to be a Sage, the reincarnation of Juno's husband Aita.
For every objective completed, Juno, the one causing the anomaly, appears and tells the Initiate of her past and rise to power. After Lydia kills the Sage, Juno thanks the Initiate for discovering his fate, and suggests that she and the Assassins could work together in the future.

Story expansions

==== The Dreadful Crimes ====
At some point following their arrival in London, the Frye twins are approached by Henry Raymond, a penny dreadful writer, and his follower Archie, and the four team up to solve a series of mysterious murders across London. The twins are eventually summoned to Buckingham Palace by Frederick Abberline, to solve the apparent murder of a Queen's Guard. Archie, who has been conducting his own investigation, discovers the culprit to be none other than Raymond, who plots to steal the Queen's Sceptre of the Dove. Raymond posed as the murdered guard to learn the combination to the safe where the Sceptre is kept by watching Queen Victoria open it, and has also faked a bomb threat to cover his escape. While Jacob and Evie evacuate the palace after learning of the bomb threat, Archie tries to stop Raymond, only to end up captured. With Raymond holding Archie hostage, one of the Frye twins distracts Raymond while the other kills him, saving Archie and recovering the Sceptre. In the aftermath, Jacob and Evie encourage Archie to try writing writing detective fiction himself and he is revealed to be Arthur Conan Doyle.

Jack the Ripper

Set in 1888, twenty years after the events of the main campaign, this expansion follows Evie as she investigates the murders of female Assassins operating as prostitutes in the East End of London, which were carried out by the titular serial killer. The Ripper has rallied former members of the Rooks to his cause to help him carry out his killings, and has also kidnapped Jacob, now the head of the British Brotherhood, who has a personal connection to the killer.

The Last Maharaja

After confronting Duleep Singh about his lack of commitment to the people of India, Henry enlists the help of the Frye twins to persuade the Maharaja to reclaim his birthright. The twins recover Singh's letters to his mother, which were intercepted by the British Indies Company (B.I.C.). This convinces Singh, who asks the twins to recover Punjabi gold, before arranging for it to be shipped back to India. He then proposes to recover the Koh-i-Noor, an Indian diamond kept in the Tower of London. The twins accomplish this task; however, Henry reveals that the recovered diamond is a replica, and that the true Koh-i-Noor never left India, having been hidden years ago by Jacob and Evie's father Ethan, who was given the diamond by Henry's own father, Arbaaz Mir.
The twins later head to a B.I.C. factory and stop the company's production of chemical weapons. In the process, they discover that Brinley Ellsworth, a B.I.C. representative and childhood friend of Singh's, is a Templar and behind the recent plots against the Maharaja. Singh arranges a meeting where he confronts Ellsworth, who tries to murder him. Evie subdues Ellsworth, but Singh chooses to spare his former friend's life and allows him to leave, claiming that they would be no better than the B.I.C. if they killed him. Afterwards, Singh thanks the twins for their contribution and parts ways with them, vowing to continue his mission.
