The commotion surrounding a lecture on magical item creation given by a Saint Level Professor, as the rumours in the room were, drew all the women who had been more interested in chatting with Cassie and Ella away from the side room, leaving the two free to rejoin Wolfe.
Only, they found that he was the Professor in question, and he really was giving them a lecture on magical item creation.
They didn't know what he was planning to teach them, but hopefully, he wouldn't give away too many of the secrets that might lead the people of this world to begin understanding the military technologies of their world. These magic users were still at war with the Demon Realms, and they didn't want to upset their allies at home, or force regional Guardians to return to protect their holdings in the Demon Realm from armed invasion.
That would make this entire trip a disaster, no matter what they might have gained from the Lowest Planes.
