Un spectre sombre plane au-dessus de l'obsidienne, coiffé d'une couronne bleue lumineuse

A mysterious, ominous dark fantasy wraith levitating just above a vast expanse of black obsidian ground, covered with countless small and large jagged obsidian shards and fine volcanic dust. The figure is wrapped in a long, tattered black robe, violently billowing and twisting in the wind, its ragged edges dissolving into the surrounding darkness. Its head is encased in a sinister black metal helmet crowned with an intricate, otherworldly crown radiating an intense, fluorescent electric-blue glow. Wisps of luminous blue smoke seep from the narrow eye slits, creating an eerie, supernatural gaze. The entity floats in a battle-ready stance, legs slightly spread and bent at the knees, arms bent and held away from the body, hands extended with fingers widely splayed in a threatening, spellcasting gesture. Vivid crimson-red energy emanates from between the fingers of one hand, casting sharp red reflections across the glossy obsidian fragments below. The entire landscape is immersed in absolute darkness, illuminated exclusively by the cold, radiant blue light of the crown and the intense crimson glow of the hand. Deep blacks, midnight blues, subtle indigo undertones, and piercing blue and red highlights.
