Julyan, a colonel within the Galactic Empire, held the position of instructor for a Strategy and Tactics course at the Arkanis Academy, situated on the planet known as Arkanis. Possessing a gaunt appearance, a bald head, and a long, downward-pointing white mustache, he was known for his energetic teaching style and constant movement around the classroom during his lectures. Zare Leonis, a human male Imperial cadet, distinguished himself as a talented student in Julyan's course. Nevertheless, after Leonis was exposed as a traitor within the academy, Julyan himself presided over his military tribunal, ultimately issuing a sentence of death.
