You get to see the first glimpse of my foal for Twilight, Flash Sentry and another royal guard I had the honor of naming Cod.
Name? Silver Nebula.
Background? Well, you're getting it right here right now. She was abandoned at a young age, due to a rare disease only unicorns can get. Remember when Twilight first got her cutiemark, the explosion of light, how she turned her parents into potted plants and went haywire? Imagine that, ALL THE TIME. No spell can cure it. Only possible 'cure' is to kill the foal, or abandon them.
