The individual holding the title of Head Proctor served as the leader of the Proctors under the command of Lord Hethrir. This Human male, still quite young, was easily identifiable from other Proctors because of the many medals he wore. Known for being a harsh and cruel bully, the Head Proctor was prone to fits of anger and displayed poor manners, often throwing tantrums. He was stationed on Hethrir's Worldcraft, acting as the Lord's second-in-command, and therefore also held authority over the Helpers.
During 14 ABY, while Hethrir was away attempting to sacrifice the Force-sensitive Anakin Solo to Waru at Crseih Station, he found himself trapped within a holding cell by Jaina and Jacen Solo. Subsequently, the Solo children freed the other captive children from the facility and escaped aboard the sand dragon known as Mistress Dragon.
The children then escaped on the sand dragon, traveling through both a forest and a swamp, with the Head Proctor, his Proctors, and Helpers in pursuit. Unlike the children, who were mostly unharmed, the Proctors and Helpers sustained injuries from the dense foliage and became stuck in the swamp before Leia Organa Solo, Chewbacca, and Rillao arrived in their yacht, the Alderaan. Adding to their troubles, they were forced to traverse the desert, where they were constantly harassed by Mistress Dragon.
The Head Proctor surrendered to Leia in exchange for protection from Mistress Dragon and other perceived "plagues." As part of the surrender terms, he was stripped of all his medals and imprisoned in a holding cell at the compound. Following the collapse of the Empire Reborn movement, it is believed that the Head Proctor was apprehended and taken into New Republic custody.
