A chilling portrait of power and decay. A bald necromancer, his skin as pale as bone dust, stares directly at the viewer with unsettling, fully black eyes. Arcane markings etched into his face pulsate with an unholy light. He is draped in long, dark robes that seem to absorb all surrounding illumination. Scattered around him are macabre occult items- skulls grinning ominously, ancient grimoires bound in human skin, and candles flickering with sickly green flames. Compose the image as a disturbing solo portrait of the necromancer from a side view, capturing his full body. The lighting should be dimly lit, casting harsh shadows that emphasize the grotesque details. The overall mood should be one of oppressive dread and unsettling curiosity.
