Mystery of the Lighthouse: A lighthouse standing tall on a rocky coastline at night. The dark, cloudy sky is illuminated by a bright moon shining through the clouds to the right of the lighthouse, creating a dramatic and atmospheric effect. The light emanating from the lantern room atop the lighthouse casts a warm glow over the surrounding rocks and sea, while the black silhouette of the lighthouse provides a striking contrast against the lighter tones in the background. The overall mood is one of mystery and intrigue, with the dark and cloudy sky adding to the sense of foreboding.
