Scene Elements: A dimly lit forest at night, with a deep blue night sky as the background, surrounded by trees and ferns, creating a tranquil and secluded woodland atmosphere. Lighting and Mood: Cold blue nighttime tones as the base, with the character emitting warm white light to create a soft contrast between light and shadow; the light is hazy and envelops the divine presence, producing a solemn, ethereal, and sacred mood.
