Instructors were the educators residing on the world of Kegan, also known as the planet. These rigid teachers, such as O-Bin, delivered The Learning syllabus to pupils at the Learning Circle, which was situated beyond Kegan's urban area. The Instructors collaborated with fellow educators at the institution; these included the Truant Guides, responsible for preventing student absenteeism, and the Security Guides, who upheld discipline and guaranteed that students remained within the school's confines.
