Metaphor
Luna didn't care one way or another about muggle things, but she had a passion for puzzles.
Muggle puzzles were the untouched paradise—a world of mind-numbing traps and tricks she'd never seen before. A puzzle that didn't require magical knowledge or skill was as alien to Luna as the concept of a computer. Upon discovery, she latched onto them with a glee normally reserved for issues of her family's magazine.
Sometimes, late at night, she could be found in the Room of Requirement with The Boy Who Lived, learning how to make jigsaws that didn't speak and towers that didn't dance.
