Mulberry wonders if it's possible to make illusions with magic. She doesn't remember reading anything about that. She could read more of the book, but that would take some hours to do.
The mare thinks, and remembers that Antoine broke the walls between both the apartment adjacent to his and also the floor to get to the general store. Mulberry wonders if there are perhaps passages she hasn't quite found yet.
Of course, she could also play around with the runes more. As well.
