The Mint is a Southwark gang stronghold for Octavia Plumb's Blighters, on the site of an old mansion once used for minting coin. Burn the heist plans and stop lookouts calling reinforcements for full sync.
The leader passes on Plumb's call for volunteers to fight the Rooks and dismisses the Rooks as about as powerful as they are pretty.
Southwark's two strongholds are The Mint and Jacob's Island. The borough also has Templar hunts on Phillip Beckinridge and Myrtle Platt, bounties on Anna Abramson and Albie Vassell, and three factories: Blackburn Bellows, Hightower Coal and Southwark Spinning Mill.
The lookouts are the main threat to full sync: if one of them raises the alarm, reinforcements arrive and the condition fails. Find the lookouts and take them out quietly before anything else, then hunt down the heist plans and burn them.
The site once held a grand mansion that Henry VII used for minting coin, which is where the area's name comes from.
Jacob's Island
Jacob's Island is a Southwark gang stronghold in a disease-ridden district long known for villains and radicals. Keep the lookouts quiet and kill the leader undetected for full sync.
Battersea Bellows
Battersea Bellows is a Lambeth gang stronghold that Cletus Strain built on a stretch of industrial land once full of housing. Kill the leader undetected and free the captured Rooks for full sync, then claim it for the Rooks.
Black Swan Yard
Black Swan Yard is a riverside gang stronghold in the City of London, an abandoned site Bloody Nora's Blighters took over after several failed developments. Keep lookouts from raising the alarm and kill the leader undetected for full sync.
Blue Anchor Alley
