The Other Side
Those ponies…Who did they think they were, trying to ruin my plan? Ever since our first appearance, we had to fend off dragons. Our crystal coats would attract them and we had many a pony eaten by those vicious creatures. The only way I could think of to protect my people was to make them unhappy. This diminished their crystal coats into normal pony coats, causing less dragon attacks. It was a bittersweet deal, but I was willing to do anything for the good of my ponies.
Then, Princess Celestia and Princess Luna of course thought I was an evil tyrant and banished me away in the form of a shadow. While I was gone, I needed a way to continue defending my kingdom, so I made it vanish. This would keep my people alive and well until I could return.
When I was finally able to come back, Princess Celestia obviously had to find a way to take me out, yet again. But, my people were my top priority. I had to get into my kingdom, to help them before the dragons returned. Ironically, a baby dragon defeated me, just as I almost resumed control over my land.
Now, I spend my days worrying for my kingdom. Will they be able to fend off dragon attacks? Are the new rulers capable of such responsibility? Oh I'll be back. And I'll find a way to take back what's mine, no matter what the cost. You'll rue the day you messed with King Sombra and the safety of his kingdom.
