The Westminster gang war is the fight against Lilla 'the Bludger' Graves and her Blighters for control of the borough. Graves opens by snapping the neck of a captured Rook, so expect a hard brawl.
Graves joins after several Blighter casualties and is killed, and Westminster comes under the Rooks.
Lilla Graves agrees to the war once her Westminster operation is weakened: the Templar hunts on Wallace Bone, Beatrice Gribble and Edgar Collicott, the bounties on Harrison Harley, Ivan Bunbury and Wade Lynton, the Devil's Acre and Blue Anchor Alley strongholds, and the Red Growler Distillery and Goodfellow's Brewery factories.
After her parents died, Graves built a name as a fearsome criminal and a heavyweight boxing champion. Crawford Starrick picked her as a Blighter leader, and she trained with Maxwell Roth before taking Westminster. Her sister Mildred is a bounty target in Lambeth.
She is a boxer, so expect her to hit hard up close. Clear her Blighters with the Rooks' help first so you face her one-on-one when she steps in.
Mildred Graves
Mildred Graves is a Lambeth bounty: the indebted sister of Westminster gang leader Lilla Graves, who works at a Lambeth cemetery and has been burying Lilla's victims without death certificates. Kidnap her and bring her to Abberline alive.
