October 5th marks the release of a Halloween ComicFest themed adventure called "The Haunted Dungeon". The cover for it is completely different from the actual synopsis, which you can find down below the break!
Strange things are afoot in the Crystal Empire so Shining Armor calls in his sister Twilight to help find the source of the mysterious occurrences. When the trail leads to King Sombra's dungeon, will the siblings find the culprit - or their doom?
Thanks to Feather Data for the heads up.
