Not many of the Demons were actually in the waiting room, as it was mostly intelligent magical creatures just relaxing for the evening. The Demons were, for the most part, untrustworthy jerks that their witches weren't willing to leave unattended, especially around each other, when they could share ideas without supervision.
There were a few Familiar Cats, a couple of pixies and a Dryad who all looked like good company, though, as well as the Imp that Wolfe had met during his first visit to the training hall.
"Wolfe, good to see you again. And you've brought Gertrude. Good choice. She's really sweet. Just pick a seat, we've got plenty of food and drinks, but my mistress forbade any alcohol. If I see it, I have to destroy it." The Imp greeted him.
The Witch waved at the Imp and visibly relaxed when the door closed behind their group and latched in place with Professor Miranda on duty guarding it.
