Following the dean's instructions, the dozens of core mages formed different teams from the people on the wall. Each group has at least five hundred people.
The three Gates on the three sides of the wall received more reinforcement as those places needed more defense than the other parts. Of course, the main gate also received more people.
Smaller teams were further formed to aid the different groups that had been stationed all around the walls. These included teams that were responsible for supplying potions. Casualties would be inevitable in this battle, so having people to provide Mana recovery potions and healing potions was a must as people won't get the chance to rest as there were not enough people to switch places with.
