Can some one make a story about this

BUT with Raven Inkwell

Funny enough, and this ties is with the 'Is she an Earth-Pony or Unicorn?' thread as well. But this is my head-canon to explain how she appears as both. Yeah, animation errors aside (like we don't see those supposed alicorn-guards) this would be something I can see happening to Raven, gaining her magic when she 'ascended' to work for Celestia in Canterlot.
