Ghost in a Watercolor Portal Chamber

An ethereal ghost drifting inside an ancient portal chamber. Painted in soft watercolor washes: translucent blues, lilacs, and greens bleed into each other. A circular stone portal glows with a lavender-white center, swirling mist and tiny sparkles. Surrounding walls are etched with weathered runes and ornate gears. Moonlight streams through a broken skylight, casting cool, diffused light across the scene. The ghost wears a tattered, flowing gown that dissolves into mist as it hovers just inside the portal; its face is calm and haunting. The composition emphasizes the contrast between solid stone and vaporous apparition, with delicate brushstrokes, soft edges, and watercolor texture.
