Chancellor is a civilian guard at Butcher Bay Correctional Facility guard section.
He noticed Riddick carrying booze, that he got from Jenkins earlier, and made him an offer to buy it, for 50 UD. When Riddick decided to sell it, he seemed relieved and told Riddick how Butcher Bay sucks the life out of you. He had four inmates hang themselves during his watch in ten days. He also gives a pack of cigarettes as an extra payment.
