I know there is a thread about the episodeItsz about time, but is about that particular place Twilight mentioned, the Tartarus Gate which keeps unspeakable evil that could destroydestroy Equestria. According to Greek Myth, Tartarus is the name of a deity and a pit where the judged are sent after death. Does this mean the pony version houses condemned beings that did wrong in Equestria then? What could possibly be sealed that a guardian who can be led away with a chew toy is between the safety of ponies and certain doom if opened?
