AHS 13 Hell on Earth
From my understanding by the leaked promo we saw from the video of the cast hinting at what the season is going to be I can safely assume the season will involve the ghosts of past AHS characters.
These ghosts will possibly represent a specific season each and are somehow released from either their location where they died or hell itself. Since we know the Murder House and Hotel Cortez are hellmouths, portals to hell, I’m assuming the Apollyon building will be another Hellmouth, but the mother of all Hellmouths.
Ben DeSoto will most likely be the catalyst of why these evil spirits are released because he’s either a warlock or actually Devon Campbell aka the new anti christ. As we all know Michael had the ability to descend into hell and basically grab anyone trapped their back into the living, as well as freeing a ghost from their haunting location. So I’m assuming that Ben will perform some kind of ritual to open the Hellmouth of the Apollyon that will create some sort of reaction that opens other Hellmouth’s across the country.
Now since the witches are returning specifically Cordelia, Marie, Mallory, Queenie, and Madison they will be the driving force on stopping Ben’s sinister spell, but how will they do it is beyond me since witches can’t use their magic to negate evil forces or can they? I believe that Mallory’s Tempus Infinitum power will come into play as well.
Now if I was a writer on this season I would create a fun spell the witches could use on the ghosts, even though it’s believed that witches can’t use their magic directly on a spirit.
The spell would be called “Mors Erit Tibi”(Death Becomes You). This spell would allow a witch to make a ghost experience their death all over again, pain and all.
