On a midnight train, one mare travels to Canterlot. She goes to see Princess Luna, presiding in her Night Court. With her, she carries determination and a book. The book has been passed from parent to foal, from generation to generation for a time longer than most ponies can even imagine.

She travels to Canterlot to give the book to Luna.

And neither pony will be the same after.

Inspired by the exquisite fan work: Children of the Night.
