Aural Blink was living the dream. That is, if your dream was being one of the most feared soldiers of the Equestrian Guard. Then the metaphoric manure hit the metaphoric fan.
The corrupt arch-sorceress Marelin returns, ready to take over Equestria. Blink doesn't like this.
Now on a mission to Ponyville, he has to protect the newly-crowned Princess Twilight Sparkle from the murderous psycho-pony while trying to find out exactly why Rainbow Dash wants to spend so much time with him. Oh, and there's a ball to be had in a few weeks, with plenty of possible security problems thrown into the crowd. Nothing can go wrong, right? Right?
Oh, and did I mention that not only does he have to remain emotionally removed from the operation, but also cannot let his cover be blown? Emphasis on the emotionally removed.
