And I did say below that I think there might not be one... But here are my three theories now.

1.) The ghost of Nightmare Moon - Nightmare Moon "died" in that castle when the Mane 6 restored Luna, and don't ghosts haunt the place they died? (Maybe she'll get a rainbow shockwave death scene when they re-kill her)

2.) Starswirl the Bearded - Play the "friendly ghost" card and have him make an actual appearance, of course probably make him out to be menacing at first

3.) It's all a trick by Discord

I had a fourth theory, but certain events have caused me to scrap it
