The same year the childhood trio forms, Zayne is accepted into Skyhaven University Medical School at age 14 — far younger than anyone else in his cohort. He later mentions that being the youngest by years made friendships at university difficult. His departure for Skyhaven ends regular contact with MC and Caleb for years. Both Caleb and Zayne attend Skyhaven institutions — Caleb at the Aerospace Academy, Zayne at the Medical School — though the wiki does not document any shared time there.
