Hidden Darkness and Silent were part of a secret science department controlled by Celestia and Luna. But they were put into an asylum after they were deemed too dangerous. Now they've escaped to help stop the misuse of their creations. All of them. But then they find out that one of them isn't showing up. Anywhere. Which means that someone not only knows of them, but has kidnapped one. If the government finds out about them, they all could get killed.

I have changed the coverart to a human photo of Hidden Darkness and Silent when they're 15. Enjoy.
