Illusionists and everything they were involved in, had to be the most put-together thing, across all of Arberus. Everything was so organized, as if the war wasn't affecting them whatsoever.
Sure they were in the rich country of Partinus where resources were to their favor, but illusionist sects didn't really struggle much elsewhere. They had everything they needed, and therefore could focus on the finer things in life; Magic.
The team understood that, once they reached the university which was in a town nearby. There were so many illusionists here, enough to intimidate anyone.
One would be scared to mess with them, because with so much collective power in this one single place. It was fair to assume that they could invade a country, if not more!
