A young elf knight adorned in celestial armor, each plate shimmering like constellations under moonlight. She stands poised in a dense, magical forest, her blade glowing faintly with runes of ancient power. Around her, fireflies drift like stardust, illuminating the dark with soft golden hues. Her long silver hair flows gracefully in the breeze, and her eyes glimmer with an ethereal glow. Artistic style inspired by Yoshitaka Amano, blending surreal fantasy and intricate detail.
