Balberith would be a tall, skeletal demon, with black and ash skin

Balberith would be a tall, skeletal demon, with black and ash skin, like volcanic rock. His head would be crowned with twisted horns, and his eyes would be bright red pools, full of malice. She would wear a dark robe that moves as if it were alive., and their hands would have long sharp claws. Around it, small flames or ashes would surround their feet, evoking his connection to the underworld and betrayal.
