In Assassin's Creed Syndicate, London is controlled by the Templars at the beginning of the story.
Set in 1868 during the Industrial Revolution, Syndicate follows twin Assassins Jacob and Evie Frye as they arrive in London. Crawford Starrick, the city's Templar Grand Master, controls institutions and criminal networks through a broad organization known as the Blighters.
The Frye twins build an Assassin gang called the Rooks and work with historical allies including Henry Green, Clara Dowe, and several members of London's underworld. Their campaign involves liberating boroughs, disrupting Starrick's influence, and confronting the social problems intensified by industrialization.
London is the game's single main setting, but its boroughs provide varied environments, from Westminster and the City of London to Whitechapel and the Thames. The game also includes famous figures such as Charles Dickens, Charles Darwin, and Queen Victoria, blending real Victorian history with the series' fictional secret conflict.
