Jacob Frye leads the Rooks gang in London in Assassin's Creed Syndicate.
Jacob and his twin sister Evie are the two playable protagonists of Syndicate, which is set in London during the Industrial Revolution. Jacob focuses on building a street gang called the Rooks and taking territory from the rival Blighters, while Evie generally concentrates more on stealth, investigation, and finding Pieces of Eden.
The Rooks help Jacob weaken Templar control over London's districts. Players can recruit gang members, liberate boroughs, and use the gang in missions and street activities. Jacob's aggressive style contrasts with Evie's more methodical approach, although both can be controlled in free exploration.
The game includes historical figures such as Charles Darwin, Charles Dickens, Florence Nightingale, and Queen Victoria. Jacob and Evie are siblings, not interchangeable versions of one protagonist; their distinct missions and personalities are a defining feature of Syndicate.
