Gumela, the Jeweled Auditor
Gumela, a second circle demon, is the wisdom soul of the Price Upon the Tower. He is described in detail on page 100 of Games of Divinity.
Vision Consorting with the Dead summoned Gumela to aid her in a failed attempt to capture the circle at Thirteen Lives Bridge. During the battle, after he had bestowed curses on most of the circle, his physical form was destroyed.
