The Executioner (CI) is the torturer and executor of Graz (Ludovico Sforza) in the Invisible Cities chronicle: a masked figure wearing an executioner’s mask, armed with a knife and a hammer.
His functions are mutilation (he cuts off Luca’s pinky), psychological terror, execution of contracts and interrogation. He is the physical manifestation of Graz’s authority, and appears in Luca’s prison.
