Illustrate a fantasy landscape during the enigmatic hour of twilight. The sky is painted with a spectrum of deep violet to soft rose, signaling the end of day. Below this vibrant canopy, a chain of rugged mountains stands sentinel, their jagged peaks silhouetted against the fading light. A dense forest of ancient trees blankets the foothills, shrouded in the growing dusk. A misty river snakes through the landscape, its surface shimmering with the last echoes of twilight, leading to a cascading waterfall that feeds into a tranquil pond. The scene is entirely natural, with no characters or man-made structures, highlighting the quiet grandeur of an untouched fantasy world.
