Powers: Provost possessed some knowledge of sorcery. He used necklaces that after being placed around the wearer's neck, could turn them to stone if activated by a mystical wand he possessed. As a safety feature for him, the necklace would automatically turn the wearer to stone if they tried to remove it. He also possessed an energy whip as a weapon. Provost was also a very educated man, who also used his knowledge of technology to his advantage in his crimes, often combining that knowledge with his knowledge of sorcery.
Bio: Provost was the headmaster of the sewer based School of the Seven Bells, where he would kidnap and enslave runaways by forcing them to wear mystic necklaces that would turn them to stone if removed or activated by a mystical wand. He would force the children to steal money for him, and trained them in the art of pickpocketing.
After abducting Molly Hayes (Bruiser) of the group Runaways, he was defeated by her and the rest of the enslaved children after they broke his wand. The feedback caused him to turn to stone and to revert the children he had previously turned to stone back to normal.
