A medium shot at eye level captures a tall, muscular woman sitting on a flat reef at a beach during dusk, her legs crossed at the ankles with bare feet resting on the sand. She has a broad-shouldered, warrior-like build with defined muscles and fair, jade-white skin revealing faint golden energy lines near her collarbone. Three obsidian-colored horns protrude from her forehead and temples, jagged and sharp. Her waist-length starry black hair flows down her back without bangs. She wears a complex black short robe with dark gold rune embroidery, high neck, wide sleeves with silver-gray trim, and a split skirt with silver fringe, held by a metal ring belt and silver chains with dark crystals. Underneath, she wears black metal armor plates on her chest, shoulders, forearms, and lower legs, exposing her midriff, thighs, and large bust. Her starry black eyes gaze calmly at a crackling campfire beside her, flames tilted by the sea breeze. The scene is illuminated by warm firelight and cool twilight, with distant waves, floating particles, and a serene, atmospheric mood.
