The sheer absurdity of the situation made Eloise want to do a little skip. She’d been enjoying a quiet afternoon at the library when she saw it – her intricate 'Celestial Map' design, rendered on the back of the librarian. The librarian was calmly stamping books.

Eloise approached the librarian, her footsteps light and springy. “Excuse me,” she began, her voice brimming with barely-contained glee. “That’s… quite the constellation you have there.”

The librarian, a woman with a severe bun and spectacles, looked up, a flicker of surprise in her eyes. “It is, isn’t it?”

“It… is indeed,” Eloise agreed, struggling not to burst into unrestrained laughter. “In fact, I created it.” The librarian blinked, then a slow smile spread across her face.
