How silly of me. I almost forgot to introduce myself. The name's Fireflash. Haven't heard of me? I'm not as well known as Soarin, Spitfire, or even Thunderstrike, although you may not have heard of him either.
"Well, I suppose the first thing I should try to do is find out who wanted me here and why." I thought. "I know that Soarin and Spitfire disappeared because somepony wanted me gone, either so I would be unable to train Rainbow, and postpone the exam, or just because I was the original target. And I know that one of the ponies that captured me and threw me in this...cave had to be a unicorn because the exit had been sealed with magic. I'll figure out who and why exactly later, because I need to get out of here somehow."
I could dig my way out, but that could take days. I can't stay in here and wait, because I don't know when somepony will notice I'm missing. They would probably just assume that I'm looking for Spitfire and Soarin, two of my teammates. I guess I'll look around this cave for a bit.
After looking around for a few minutes, I found a dark tunnel in the back of the cave. After about five more minutes of looking around, I decided that that was the only opening in the cave. Since it won't do me any good to try to dig out, call for help, or just wait, I guess that I'll explore that dark, creepy tunnel in the back of the cave for now. Maybe there's another exit somewhere in this place.....
