In The Cask of Amontillado, the mood and the atmosphere contributes significantly to the nature of the protagonist and the horror ending. The story starts in a carnival where many gathered in the spirit of festivity. The fact that Fortunado has been drinking plays an important role that lead to his death. The mood changes when Montresor takes Fortunado into the family catacomb; the atmosphere is drastically contrasted by the mysterious and eerie setting of the catacomb. Since Fortunado is not fully conscious due to the influence of alcohol, he is not completely aware of his surroundings and the readers can only see in his narrow and limited vision and perspective. The dramatic contrast between the moods emphasizes the fate of Fortunado that changed from wealthy and merry to miserably tortured in a catacomb.
