Kitty turned to regard the wardrobe again, though her eyes had never really left it. The Chronicles of Narnia were books she'd read a long time ago, back when she was in Romania - but she certainly hadn't forgotten them.

"That's a wardrobe," she said, raising her hand in the air. "And there's a classical Muggle fantasy series for children that I know which features a wardrobe: The Chronicles of Narnia, specifically the Lion, the Witch, & the Wardrobe. The wardrobe in that series was built out of a magical tree, and it led into another world with talking animals called Narnia."

Many others gave the same answer as she did, she noted.
