"Where was Princess Luna when the changelings attacked?"

A simple question, yet it has spawned numerous conspiracies. From Luna losing a bet, to Gamer Luna not being able to pause her video games and even the involvement of the Ponyminaughty.

This story hopes to tell what really happened and maybe present Luna in a new light.

Note: Inspired by the Author's Note section at the end of Adventures in Writing. After all, we need to find out how Luna happened to know that little bit of knowledge.
