Dreambound Lich in a Surreal Dream World

Concept art of a lich in a dream world: a tall gaunt undead sorcerer with a skull face and ember-blue eyes, wearing regal but moth-eaten robes etched with ancient runes. A softly glowing phylactery hovers near the chest, releasing faint blue motes. The background is a surreal dreamscape with floating islands, impossible staircases, luminous mist, and a pastel, shifting sky. Use cinematic lighting with volumetric glow, rich purple-indigo tones, pink and teal accents, and gold filigree. The composition is a dynamic three-quarter view or full-body portrait from a slightly low angle, with dreamlike distortions around the edges. Painterly digital painting style, high detail, blending watercolor-like softness with crisp concept-art lines. Mood: enigmatic, serene menace, wise and ancient. Include subtle sigils and memories in orbs, and a distant castle silhouette. No gore.
