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.
The leader relays Nora's order to watch for a rebel group rising in Whitechapel and insists the Blighters are a family, something he says the Rooks will never understand.
This is one of three City strongholds under Bloody Nora with Field Lane and Rosemary Lane. Clearing them, along with the Templar hunts on Thomas Blackroot, Eveline Dipper and the Slaughterhouse Siblings and the bounties on Harvey Hughes, Maude Foster and David O'Donnell, leads to the gang war against Nora.
Deal with the lookouts before they can raise the alarm, then reach the leader and kill him unseen. Both conditions punish being spotted, so move slowly through the riverside yard and remove the lookouts one at a time.
He tells his Blighters that Nora wants them watching for a rebel gang rising in Whitechapel, which places this raid early in the Rooks' spread.
