Act as a masterful dark fantasy artist with a specialization in eerie, atmospheric character portraits. Create a highly detailed, cinematic portrait of a powerful necromancer exuding a sinister, shadowy aura. The necromancer wears [ORNATE BLACK ROBES WITH SILVER EMBROIDERY], their skeletal hands clutching a [GLOWING SKULL STAFF] crackling with dark energy. Their face is partially obscured by a [HOODED SHADOW], revealing only glowing, malevolent [EYES LIKE SMOLDERING EMBERS]. Surround them with swirling tendrils of [MISTY SHADOWS] and faint, ghostly apparitions of the undead. The background should be a [RUINED GOTHIC CATHEDRAL] under a blood-red moon. Use a moody, high-contrast lighting scheme to emphasize the necromancer's otherworldly presence. Style: hyper-realistic digital painting with influences from dark fantasy art and gothic horror.
