Even alicorns need vacations sometimes, and Luna is taking hers. In the guise of the humble page Night Vision, Luna walks the castle halls. It will be a night of ink stains, mismatched plates, an oblivious musician, and spectacular hoofball goals. But most of all, it will be a night of fun and friends.

Directly inspired by Fizzy Orange's brilliant story 'Luna's Pet Project', which you should all go read immediately.
Written for the Lunaverse Alicorn Challenge.
You do not need to know anything else about the Lunaverse to understand this story, although reading Fizzy's story as a prequel is highly recommended.
