Create a dark, fantastical female character design of a formidable demon king

Create a dark, fantastical female character design of a formidable demon king. The mage should wear a long, wide, ragged, dark red and black robe with intricate designs and a hood that covers most of their face. They possess many arms extending from their body, each hand decorated with a fiery red flame. Their head has a pair of very long horns with glowing red eyes. Behind them, a large, ornate, red halo-like structure with sharp, jagged designs adds to their imposing presence. Shadows of tortured souls can be seen faintly emerging from their robes, creating an ominous atmosphere. The background should be dark and gloomy, emphasizing the dark power of the mage
