In literature, "slope" serves as a versatile term that extends beyond simple topography to evoke mood, atmosphere, and a journey—both literal and figurative. Authors use it to designate the angle of descent or ascent in the landscape, setting the stage for movement or transition. For instance, it marks the path of characters in rugged mountaintops and valleys [1], [2], while also suggesting a decline or a gradual progression toward a significant point, as in a river’s approach or the encroachment of decay [3], [4]. Additionally, the slope often carries symbolic weight, hinting at the passage of time or the shift between states, whether in dramatic wilderness or in the subtle transitions of a character’s inner world [5], [6].
