The evil governor of corrupt high security prison Blackmoor. Transferred to Wentworth after Rita Connors burnt down Blackmoor. His vow to kill Rita was almost taken through with but failed. At the same time he was blackmailing Lorelei Wilkinson to lag on the prisoners so he could discover what their plans were.
Rita asked Lorelei to hide the knife she attempted to kill him with but she failed to when Craven's last threat was made to blackmail her because of the alarm they used to find out when Craven was attacking Rita. She stabbed him and he staggered through the corridors until dying in front of the prisoners, Joan Ferguson and Meg Morris but he still made one more lunge for Rita.
