A pony is born with their special talent. Right?
Born to discover it when they get their cutie mark and love doing it for the rest of their lives?
What if they don't like their special talent? What if nopony does?
What if their special talent is something wrong, something evil?
Teardrop has always enjoyed one thing in life, hurting others. He's born to do it. The best there is.
It's his special talent.
Now he must make a choice, one nopony has ever had to make before. To follow his special talent as everypony before him has, or do the right thing and forsake it.
Cover art has nothing to do with story. It just looks cool and goes along with the theme.
