The Arcanist was called Beatrice, and she needed a secluded space to make the 'ritual' that would change Kai's class from Mana-Infused to Arcanist.
They couldn't do it anywhere. No one could interfere, as that would result in failure. But where could they find a place like that?
"I have a house nearby," Beatrice said, "Well, not just mine. My group and I live there."
"You live there? Why did you choose this place?" Kai asked.
"Lunengard is the place where we can find the highest number of missions. We are all adventurers, so leaving close to this place is the best thing we can do," she said.
That was a good explanation. Becoming an adventurer was something a lot of people did after they graduated from any magic academy they studied at. There were some who learned magic elsewhere and didn't have an official degree, but most of them did.
