A friend asked me for Warhammer Vinyl Scratch. And as I am enemy of all chaos ponies, as my friend is. He did not want Vinyl as Noise Marine.
So question was: Who'd be fitting for Vinyl in ranks of the Imperium?
Vinyl isn't mare of noble songs and prays. She's not somepony, who'd like to live as Sister of Battle. It's not her style. She's simple mare, like billions of Ponies in the Imperium of Ponykind. She likes simple things, enjoys common situations.
So my choice was Imperial Guard - elite of Princess' Hammer - Kasrkins from Equestria. Loyal to the Princess and Ponykind, she still loves a good music. When she just have a time, Vinyl picks up her audioplayer and leaves everything for her own piece of heaven.
This is the begining of new project - project of anthro ponies in warhammer. In my version. All ponies in forces of the Imperium. Each rank, every most fitting place for each pony.
