PROMPT:
Create a breathtakingly realistic night sky scene illuminated by a majestic aurora borealis, set against a dark blue velvet background dotted with twinkling stars. Incorporate vibrant hues of electric blue, lime green, and amber, minimizing pink tones. The aurora's wispy tendrils undulate and swirl, as if alive, with shimmering curtains of light that seem to pulse with an otherworldly energy. In the foreground, a lone, gnarled tree stands tall, its branches twisted and silhouetted against the radiant display, while misty tendrils of fog curl around its roots like ethereal fingers. The image should exude a sense of mystical wonder and awe, as if the viewer has stumbled upon a hidden celestial secret.
