He did not take his tertiary education very seriously, primarily treating it as an opportunity to party. In keeping with this approach, he proposed a questionable vault experiment to determine whether a group of canines could form a self-governing society as his senior thesis; a proposal which did not impress his advising supervisors. His connections to Hornwright Industrial meant that his progress at the university was closely monitored.
He also owned a miniature schnauzer named Riley who he had allegedly trained to open vault doors.
Liam Hornwright is mentioned only in Fallout 76.
