Night. A lone Christmas tree stands defiantly in the center of an abandoned urban plaza, its branches heavy with snow and adorned with flickering string lights—each bulb glowing warmly against the gloom, powered by a rugged portable gasoline generator humming faintly beneath its base. Around it, skeletal remains of buildings loom like broken teeth; shattered glass frames reveal smoldering fires within hollowed-out rooms, casting orange reflections across frozen streets. A weary soldier sits slumped atop a weathered wooden ammunition crate near the tree’s foot, his uniform stained with grime and frost, eyes glazed but fixed upon the luminous greenery—a silent witness to ruin. Snow falls steadily under a bruised twilight sky, blanketing everything in white silence. Cold wind whips through cracked alleyways, carrying whispers of loss. Mood: somber, haunting, melancholic holiday solitude — stark contrast between festive light and apocalyptic decay. Winter night. Stark realism meets emotional weight.
