BAT theories
Nicodemous and Nemesis both say of Apocalypse, it's not an event, it's a state of mind.. that plus the name Big Apocalyptic Trilogyis pretty much the solid basis for these theories. The rest is fragments and wild guesswork.. The quotes are from memory, so probably not precisely right, though should be close enough
Stars and Stones : Dresden in a free for all for the Starborn of the era.. Id guess Drakul is the big bad here, though I'd expect them to face off at least once before.. So all Starborn have power over outsiders but the Starborn of the Era inherits the powers of Merlin.. Not sure what the stones are exactly here, but we know that Merlin made Demonreach multiple times at multiple different times. I'd also imagine such a being would become an Immortal, due to Mab's line to him, "Immortality is no substitute for intelligent.. Remember that, if at all it becomes necessary". And Ebenezer scowls at it. Finale has the Grey Wizard, Dresden + Grey Council vs Black Council + Black Court.. Both work for life beyond Death, in pretty twisty ways (except Kumori, who is guess changes sides last min). What's the best way to beat a an army that will kill everything and everyone for a taste of their life force? Have no one living, and face the outsiders with an army of the dead.. Listens to Wind says of Starborn, that some truths can do a damn sight worse than killing you. I'd guess Drakul was a Golden Child of a previous era.
Hells Bells: Well assume that Nicodemous wants to stop Empty Night too, from all his and Deirdre's talk of Saving the World.. Well heaven can't or won't stop it, but Hell can.. Powered by a massive human sacrifice of all or most people to the Prince of Darkness.Probably Involving some creepy reversal of the Christ dying for all human sins, like making a Knight murder and Innocent with the Sword and catching the blood that flows. Doesnt bode well for Butters, whose having life be a bit too good for a major Dresden character. Or *shudder* Micheal.. He's teetered over the brink when his kids are harmed.. Imagine little Harry killed by some other confused child. He probably has some vestiges of Uriels grace still, so even without Excalibur, well...
In the end of it, as Nicodemous dies, strangled by his Noose, he spits out, "You fool, better Hell than that.. Empty Night...
And Empty Night is all of Creation, united by Harry against all the Outsiders.. Nemesis still has some forms left.. Or its either pass the buck another 666 years, or face the music..And well Harry, he'll bear the fate of all Creation than pass the buck. You see, the Outsiders don't just kill humans, they take their souls for an eternity of gnawing Emptiness in the Void Beyond... The Outsiders were originallys made by mortal choice, so Heaven cannot act to unmake them, not directly anyway.. (Otherwise, you know, wed have Uriel as a Deus ex Machina, from his off hand mention about his power to unmake Galaxies.. ) Theory here is that amab wants the White Court cause Outsiders like individuality (except Walkers I guess, though with He Who Walk Before In Between and Beyond, and non linear time constantly referenced, they're all just one Being) , a) she wants spies of her own b) some kind of sympathetic link to target all Outsiders with..
Chars by this time:
Harry and Lara are now properly in love, though if Harry is Merlin, and the White Court attitude to monogamy, he's probably getting with more..
Marcone is fully and Ally now, after Harry or likely Molly is able to wake the girl who took his bullet in exchange for his fealty
Maggie: Fully magical, some kinda prodigy, you know with Bonea + Molly + Harry to teach her. She's probably gonna be awesome at Animal Magi. And funny headcannon, when Listens to Wind and River Shoulders train Harry and despair at his skill at form changing, Maggie goes it's easy dad and ''Comes out" as a Wizard by shifting into an Elephant.
Molly: Becomes Mab after now Mab ascends to Mother post current mother's mergina dn sacrificing themselves to give our peeps a chance. but I fully admit, primarily cause I'm shipping her and Ramirez hard, and Mab casually mentions having score of lovers over the years, so the mantle is cool with Mab getting (or I suppose, giving) nookie
Eb: Is able to sacrifice himself to save Maggie, and does with a smile on his face
Thomas: Idk White Court King, cause Laras busy now (pregnant??) the strongest of his kind, who eats multiple outsiders/to be forgotten entities and powers up the fuckton needed to stand and fight with his brother
Arthur Langtry: mFinally not Merlin anymore and gets to cut loose.. Telepathy so strong he uses psychic attacks to break Outsiders, and Harry shudders when he thinks about how much he fucked with that absolute Chad
River shoulders + Kid Shoulders: Beat Genoskwa harder than Beowulf beat Grendel.. He recovered from being a blood splatter but not from this
