Princess Luna's been up for 24 hours.
She's about to go for another 12.
She also has coffee.
Flash Sentry is filling in for the sick Dusk Guard pony Ralph on the same day Princess Luna came to visit his guard station. On a seemingly innocent Bugbear hunt no less. One would assume that he would know what he was getting into.
A short tale set in the Somepony Universe which may or may not have several more chapters added as time goes on. This fic takes place the same day as the Luna Micro Series ends.
