She goes by Ghost. The white unicorn mare is a legend. Nopony under her protection has failed to come back unharmed. A great shot with a set of impressive power armour, she is the last thing many raiders see.
But what they don't know is that Ghost is nothing but a bit of illusion and trickery. A front for my true form. My name is Kelsey-090. This is my story.
Little bit I wrote to get out some writers block. Just came to me when I was reading Fallout: Equestria. "Let's chuck in a SPARTAN to kick ass and take names! What the hell, why not!" So boom, have some human/SPARTAN in (Fallout) Equestria!
Also gore tag because fallout. Nuff' said
