What was that charm Bee had mentioned earlier? The one that repelled stuff... Like water and dirt and dust kind of stuff? Impervius, yeah? Yeah. That was it! Ella eyed the desks near her curiously and tilted her head. It'd be a really good idea to use this charm now that they were clean, right? That way they'd stay that way and the students wouldn't have to worry about them! See? It was a very helpful charm to use.

The badger bit her lip and practiced the incantation in her head a few times before tapping the first desk and saying, "Impervius!" Welp. Hopefully that worked. On to the next. Tap. "Impervius!" And on and on and on. Tap. Tap. Tap. "Impervius! ....Impervius! ...Impervius!"
