Because he was a year older, Kieve entered the academy earlier than Zandro. His days in that place were peaceful and he enjoyed every moment of it but when Zandro entered the following year, it became a chaotic experience. At the age of fifteen, the crown prince became even more arrogant that his own parents noticed it too.
They then decided to send him to the academy in hopes of changing his attitude and yet it became a regret at the end. Zandro started to gather people who would later on become his servants. They would go around the academy and flaunt their power and wealth.
The Academy was a place where anyone had the privilege to enter as long as they had the aptitude for it. Neither the royal family nor the high magus's family had control over that place. It was an independent institution that aimed to mold and teach the future generation of the kingdom.
