Parasitic purple hands, attaching themselves to victims with their spikes. The left-hand "sinistral" noble class rule whichever secret handlinger community they are a part of, as they have the ability to shut down the dextrier's control over its host at will. These right-hand "dextrier" warriors, however, are perhaps more terrifying for a non handlinger, as they are able to fly and spit fire using the body of whichever host they choose. Handlingers hide in plain sight, hidden under excessive fabrics worn by their hosts.
Perdido Street Station Edit
During the events of Perdido Street Station and earlier, handlingers are believed by many to no longer exist, and are often used to explain the strange behavior of others. Rudgutter employs the service of ten (5 dextriers and 5 sinistrals) in order to fight against the slakemoths, and leading them is one of Rudgutter's closest allies, Montjohn Rescue, which Rudgutter had turned into a handlinger 11 years ago after he threatened to betray Rudgutter.
Iron Council Edit
Though feared by the citizens of New Crobuzon, handlingers have long been in contact with the city's rulers, and (between the events of The Scar and Iron Council) even agreed to have their presence in the city made public knowledge (along with the assertion that only the criminal condemned would be used as hosts). This development puts yet another terrifying weapon in the hands of the New Crobuzon government, but due to internal politics, handlingers were found on both sides of the Collective's failed revolution.
