Not to any specific fic (at least that I am aware of)... to be honest I really started this series of pics simply because I wanted to draw a giant starship and needed something to go in the background: ponies seemed like the thing to do.



I guess the way I see it in my head the ponies came to Equestria having left their own homeworld for one reason or another, but that was so long ago that that past is forgotten... except perhaps by the royal sisters and, as an alicorn now, Twilight also posesses the correct genetic structure to be recognised by the ship.
