Seedance 2.5 Ash Sisters Dissolve Fantasy Magical Prompt

15 second cinematic mythic short film titled ASH BREATH. Three ash-born sisters (Kael central, Rin and Vey) with consistent pale grey cracked skin that faintly glows orange in fissures, long dry matte black ash dusted hair, deep amber eyes, tall lean builds, wearing identical layered tattered charcoal and bone ash cloth, sit in a vast empty volcanic caldera under hard midday sun. Kael holds a glowing ember. They feel ground vibration, look across heat haze to distant modern expedition, Kael extinguishes the ember, all three place palms on ash and slowly dissolve into the cracked earth, leaving only faint residual glow. Locked large-format camera language, 28–85 mm lenses, shallow DOF on faces, deep on environment, high contrast desaturated volcanic grade with warm subsurface in cracks, sparse elemental drone score fading to silence, pure visual storytelling, no dialogue, no water, no wetness, no scales, no ships. Perfect character and costume continuity. Photorealistic physics, fine film grain. Negative prompt: face morphing, wet hair, ocean, mermaid tails, extra limbs, text, logos, modern clothing, over-saturated color, plastic skin, camera shake, flickering
