The V-SIS, short for Vocational School for Institutional Security, served as an educational institution on Lothal, specifically within its Capital City, focusing on the instruction of information security principles. An administrator oversaw the school's operations, and at one point, they conducted a gathering to discuss moral and ethical conduct within the information security field. Within the school's lowest level, there existed a complex series of networking labs. Among those who attended the school were Merei Spanjaf, a youthful supporter of the rebellion; Jix Hekyl, a Pantoran individual; and Bandis Yong, a slicer who possessed an inflated sense of self-importance.
