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.
Kingdom Hearts: Chain of Memories
In "Reverse/Rebirth", which occurs congruently with the game's main story, Riku is transported from the realm of darkness to Castle Oblivion's deepest basement, and he fights figments of previous enemies to combat his inner darkness as he climbs upwards. Vexen fights Riku to obtain his data and creates his replica to counter Marluxia's plan. Ansem, still possessing Riku's body, tries to regain control of Riku, but Mickey's power keeps Ansem at bay. On the way, Riku battles and defeats Lexaeus, a member of Vexen's circle, only to be dragged into the realm of darkness. However, he is saved by Mickey when Ansem nearly succeeds in taking Riku's body as his own. With Marluxia eliminated by this time, another of Vexen's allies, Zexion, attempts to dispose of Riku by drowning him in light. Riku is saved by Naminé disguised as Kairi, who helps him to control his darkness, allowing him to defeat Zexion. Riku later meets DiZ, an enigmatic individual interested in Riku who sends him to find Naminé. Riku's replica, who has since learned of his altered memories, seeks to justify his existence by killing Riku, only to be destroyed by him. Riku chooses to face Ansem upon learning from Naminé that Ansem lives in his heart, and defeats him after DiZ summons him for Riku to fight. Riku then sets out on a journey to utilize both his darkness and his light with Mickey as his companion.
