Let's play!

The Three Sentence Ficathon is a thing this year (I am so chuffed). Want to know what happened when Minerva McGonagall and Mary Poppins met or when George Weasley met Amy Pond at Maria Lu's request? The prompts do start off Narnia heavy, but get more wild and wonderful. (You may want to consider filling some of mine on page 14...)
