Wist Ebony entered the Potion room and looked at the professor. It was a bit hard to imagine her as a student. But she looked happy, and that encouraged Wist in what she was about to do. "Hello professor." She picked up three snowy owl feathers. "I wasn't sure what feathers you wanted, so I took feathers that had fallen from most species of owl at Hogwarts." And then she opened her packpack and took out a bout thirty feathers. Then she went back to her seat, smiling to herself.
