A vast landscape slowly being swallowed by a looming darkness that spreads across the sky like ink in water. The horizon fades as an ominous shadow blankets the Earth, extinguishing the last traces of daylight. In the distance, faint outlines of mountains and cities are barely visible under the thick, black shroud. The once vibrant sky now turns a foreboding shade of deep gray, with the darkness creeping closer, engulfing everything in its path. The world seems to hold its breath, as the last remnants of light disappear, plunging the planet into a haunting and unnatural night.
