Here's a bit of almost groundless speculation. Though since we've been talking about ghosts lately, I might as well toss the idea out there...

The "Pony of Shadows" may be the ghost of either Starswirl or Clover.

They are the only known non-alicorn ponies aside from the leaders of the three tribes who are ancient enough to have dwelt in the sisters' old castle. Since it is evident that they contributed much to Equestria's development, I would not be surprised if one of them is still lingering around its first palace...

I'm still betting that this will be an entirely new character nonetheless.
