Heart of Darkness
Heart of Darkness (1899) is a novella by Polish-English novelist Joseph Conrad about a narrated voyage up the Congo River into the Congo Free State in the so-called "heart of Africa". Charles Marlow, the narrator, tells his story to friends aboard a boat anchored on the River Thames. This setting provides the frame for Marlow's story of his obsession with the ivory trader Kurtz, which enables Conrad to create a parallel between what Conrad calls "the greatest town on earth", London, and Africa as places of darkness.
Gabriel Knight
All three games in the series focus on the adventures of Gabriel Knight, a New Orleans author and bookstore owner who finds that his destiny is to become a "Schattenjäger", or "Shadow Hunter". Gabriel's assistant, sidekick, and sometime romantic interest Grace Nakimura is a major supporting character in "Sins of the Fathers". In "The Beast Within" and "Blood of the Sacred, Blood of the Damned", she shares the role of protagonist with Gabriel. The player alternates between Gabriel and Grace for different portions of the latter two games.
