Photorealistic Lich in a Desert Canyon

Photorealistic image of a lich, an ancient skeletal necromancer, standing in a wind-swept desert canyon at golden hour. The lich wears tattered, rune-etched robes and a tarnished crown; hollow eye sockets glow with eerie green light. One hand grips a gnarled staff topped with a cracked crystal, the other raised as if guiding necromantic energy that wisps into green motes. Surrounding scenery features towering red sandstone walls carved by wind, swirling dust, heat haze, and distant mesas under a warm amber sky. Cinematic lighting with long shadows, rich ochre and sienna tones contrasted with cool blue shadows; shallow depth of field with sand grains in sharp focus in the foreground and a softly blurred canyon background. Mood: eerie, mysterious, awe-inspiring, with a subtle sense of ancient magic; no gore.
