Kurtz an ivory trader for the Company. Kurtz works out of the Inner Station and is remarkably effective at acquiring ivory. A well-educated European, he is described as a "universal genius" and begins his work in the Congo as part of a virtuous mission. However, while in the jungle, he sets himself up as a god to the natives. By the time Marlow reaches him, he is emaciated and dying.
The Manager Working out of the Central Station, the Manager oversees the Company's activities in the Congo. (He is based on a real person, Camille Delcommune.) The Manager is able to inspire uneasiness in others; Marlow later figures out that he was responsible for the wreck of his steamboat. The Manager fears that Kurtz is trying to steal his job.
The Accountant Also working out of the Central Station, the Accountant somehow manages to wear spotless clothes in the sweltering heat and complains about the groans of a dying man who is brought to his office for fear of being distracted and making clerical errors in the Company's books. He also confides to Marlow some of the Company's shady business practices.
The Brickmaker Although his name suggests the nature of his position, the Brickmaker does not make any bricks because of a shortage of materials. When Marlow meets the Brickmaker at the Central Station, Marlow suspects that he is "pumping" him for information about the Company's plans.
The Harlequin a Russian freelance trader who meets Kurtz in the jungle. He admires Kurtz immensely, telling Marlow, "This man has enlarged my mind."
