[Blue Tower, Wizard Academy]
Every year, qualified wizards would get a promotion. Those who were the best will learn more difficult magic spells according to their type of magic.
Each class had five levels of learning. The light blue robes were level one to five, the navy blue robes were level six to ten, and the dark blue robes were eleven to fifteen. And after they passed all that learning, they would become wizards who were ready to serve outside the magic tower. (At that time, Ace was at level 9 while Edith was 10.)
