Wanda
Into the room Wanda went - or actually, she waddled there. Feeling very large and like one of those round Christmas tree ornaments - or perhaps like a Christmas turkey? She felt ready to pop at any rate.
It was also possible she would be distracted by the library - plus, she could feel the crackle and shimmer of magic in the air, some kind of spell. She wondered what Stephen had concocted.
Only one way to find out, so she said her name and toiled patiently.
