A spectral monarch adorned with a luminous golden crown and opulent necklaces, radiating an aura of ethereal power, is framed by a sunburst headdress that gleams with celestial light. His eyes, vacant and milky, peer out from a visage of pallid, withered skin, embodying a stark contrast to the vibrant regalia. Bathed in intense, atmospheric lighting, every detail of this regal apparition is rendered with stunning photorealism, set in an 8k resolution, with a towering, elongated aspect ratio that emphasizes the imposing presence of this undead sovereign.
