Desolation can be used to describe loneliness, sadness, helplessness, and other emotions. Here are some examples: In the deep night, the moonlight cast a faint shadow through the treetops, and the entire city fell into silence. Only the sound of footsteps echoed in the empty streets. On a rainy night, there was only a street lamp and a figure hurrying past. The surrounding scenery seemed gloomy and desolate. The autumn wind was blowing, and the leaves were falling. The entire park became empty, only a few dead trees stood alone in the cold wind. At night, the waves on the beach beat against the reefs. The lonely lights seemed a little fragile in the night, and a desolate atmosphere filled the air. The ruins were only covered with dead leaves and dust. The once prosperous scene was gone forever, making it seem extremely desolate.
