#theory!

the empire isn’t brought down by this particular boy, it’s another one, 10-15 years down the line.

cal will be 30-something before he sees freedom again, if he makes it that long.

he doesn’t rebuild the jedi order. he doesn’t even make a good dent in the empire’s power.

So, we finally got the TWP titles! Woohoo!

Except the third one's called The Last Shadowhunter. And we are all dying a little inside because of it.

But, it may not be what we all, in at least some part of our brains, believe.

Now, before I begin with my probably crazy theory, I've been thinking about one thing ever since the titles came out, namely The Last Shadowhunter. So, Lucifer is our main villain, right? And villains, as we all know, are hugely fond of giving our heroes nicknames. So, what I'm thinking, is that Lucifer calls Kit Last Shadowhunter. I promise, it fits in my theory.

Now, we all read the Shadowhunters wiki about The Wicked Powers, yes? And it says over there that all the different generations of Shadowhunters that we have read of so far will have to band together to save the world, and Angel knows how many other different realms, from ultimate doom.

That would require them all to come from the past, right?

So we have magic the messes with both dimensions (I'm talking Thule over here) and time, which in this case means the past.

But what if it also means the future?

Now, what I'm thinking is that our TWP gang, namely Kit, Ty and Dru, somehow, through the craziness of the first two books, manage to land themselves into a possibility of the future. Mind the word possibility.

See where this is going? Dru, Ty and Kit then find themselves in a world where the nine princes won, Downworlders run rampant, warlocks are forced to join the princes, faerie are the only uniform government left, werewolves and vampires are scattered, and worst of all, Shadowhunters are all gone.

Except for one.

Kit Herondale from the future swoops in and rescues the time-travellers from an oncoming demon attack. And yes, he can fly because he has gold wings (read my other theories and convince me otherwise). Kit having gold wings and faerie magic is my Roman empire, okay?

He stares at the three of them, Ty and Dru in particular because they're dead. There's a huge confusion at first, but then future Kit explains what happened.

So the Nine Princes of Hell won. Shadowhunters, even part-Downworlder and Ascended, are all truly dust and shadows. Because Lucifer, knowing the saying We are dust and shadows really well, he gains supreme power and turns all Shadowhunters into dust and leaves their shadows behind (this is my other Roman empire, okay? Kill me later).

And just when every Shadowhunter around him was disintegrating, and Kit saw everybody he loved die too and was glad he himself was about to die, he didn't.

Nothing and no one could explain it.

All that aside, Kit had lost his parents, his sister, his friends, Dru, Ty. And lots of other people lost too. Magnus and Max lost Alec and Rafe, Maia and Lily lost their good friends, Kieran lost Mark and Cristina (and I like to think that Kieran swore to exact vengeance for the deaths of the people he loved), and Gwyn lost Diana, and the list of people who lost doesn't end. Tessa, however, is dead too, because she is also part-Shadowhunter, but Ash is still alive because he's half-faerie, quarter-Shadowhunter and quarter-demon.

Now, Kit, Ty and Dru finally understood why Lucifer called Kit Last Shadowhunter. It was because Lucifer had foreseen a future exactly like this, a future where he'd won.

And it is in this future that Kit, Ty and Dru finally find a way to stop the Princes of Hell.

Now, I have a question for you all.

Emperor Belos is using Galdorstones to make himself powerful, isn't he?

And since he isn't an actual witch/the Galdorstones aren't meant to be used by witches (hence why nobody is allowed to use them, and the illusion coven had to scare them off), his body couldn't handle it. That and Belos being centuries old.

I just saw a very good theory that was, in essence: tommy didn't actually die. Everyone involved with the prison is canonically under the control of the egg, and tommy's cause of death never showed on the screen when he died- like what happened to ranboo during his prison visit. That also explains why there was a cat- why would tommy be allowed to have a cat in the prison when its so locked-down he can't leave?

This was all just a hallucination, and tommy is fine.
