i watched the 1986 movie and this popped up in my head but the word was the canterlot ghost, i thought it up with a ghost changeling/stallion do well looking figure as the ghost and well anypony can be the others, you can respond if you find a comic with the same style.  
i also need help with tagging, since i need to sleep now, tell me what you think of the idea.  
and well if i ever do a pony version of the story it will be antrho styled, (yesh i need to stop)
