In Assassin's Creed Syndicate, Jacob Frye leads the main London campaign.
Jacob Frye is one of twin Assassin siblings who travel from Crawley to London in 1868. He is impulsive and openly confrontational, while his sister Evie is more methodical and focused on recovering an Isu artifact. Players can control both characters, but Jacob leads the central campaign against the Templars' influence over London.
The twins establish the Rooks, a street gang that helps them challenge the Blighters, a rival gang controlled by Templar interests. Jacob's missions commonly emphasize combat, gang recruitment, and territorial control. Evie's missions more often highlight stealth and investigation, although both characters share core equipment and abilities.
Syndicate is set during the Industrial Revolution. Its London includes historical figures such as Charles Dickens, Karl Marx, and Queen Victoria. Jacob and Evie's partnership distinguishes the game from earlier entries centered on a single playable Assassin.
