Glass horse running across a vast starlit desert

A solitary glass horse gallops across a vast, starlit desert, its crystalline form refracting the light of a thousand distant galaxies. The ground beneath its hooves is composed of shimmering, iridescent sand that shifts like liquid. In the distance, colossal, ancient ruins hint at a forgotten civilization. The overall mood is dreamlike and mysterious, rendered in a surrealist dark fantasy concept art style with a futuristic hint.
