"Wow," Sadde breathes. "That's the coolest spell ever—or is it an artefact or something? I want that."
If it does wind can it do other fluids? Rain? How about perspective? Could it make a room appear bigger than it actually was (making the living room look like a wide open space)? Illusions that affect selected groups of people? Invisibility? Sensory overload? If it is told to make the Illusion of a book does the book come with information the user doesn't have? Would a mirror still work? A telescope? Do illusions cast shadows? Create actual light?
Cool. "Would you like to trade this for Fly? I can't say I have specific plans to found an Avalon, but this certainly would be helpful if I did."

Felix walks over to help with the groceries. "Yeah, she is Clow and he is the Cardcaptor. Guys, this is Isaac. He is our... let's go with 'caretaker'. Since we are minors and everything we needed someone to play the role of Responsible Adult."
Isaac blinks a little under her inspection. "Yes? I consider the twins plenty responsible, but this arrangement is easier and law-abiding."
He turns to Temple. "Are you okay?"
Temple has - since Isaac walked in the room - been looking at him in a way that makes one wonder if he's trying to manifest "heart-eyes" by an act of will. "I am great."
She tilts her head, looking at him. "Yeah I get that he's hot but we're minors," she points out.
