Dark Fantasy Obsidian Necromancer Avatar

A haunting dark fantasy character avatar depicting a sinister 30-year-old male necromancer with pale alabaster skin, dark gaunt cheekbones, and piercing glowing emerald eyes. He wears voluminous high-collared robes crafted from dark obsidian-hued velvet and tattered black silk, embroidered with silver skull runes and horn-like pauldrons carved from dragon bone. Long raven black hair falls untamed around his face, and a silver tiara shaped like interconnected thorns rests on his brow. Set inside an ancient Gothic stone crypt filled with melting tall white candles casting flickering warm candlelight, misty shadows, and floating green soul-fire embers rising from a dark altar. The lighting features extreme high-contrast lighting with cold green soul-fire key light from below illuminating his facial bone structure and warm orange rim light from the background candles filtering through his dark hair. Framed as an intimidating chest-up avatar portrait centered in the frame, holding a skull staff that pulses with ethereal green magic. Rendered with dark moody cinematic color grading, rich deep shadow blacks, photorealistic cloth textures, eerie dark fantasy aesthetic, 8K digital art.
