So you know how at the end of Nona the Ninth, Harrow doubts that John is god and goes off into the River to find god, who is maybe Alecto?
It turns out we had a clue right at the beginning that John is not the metaphysical engine of the universe of The Locked Tomb...
When Teacher gives the assembled scions at Canaan House a highly selective history of the OG Lyctors, he says:
Those eight necromancers were first after the Lord of Resurrection; they have spread his assumption across the blackness of space.
Remember that John is, in the theology of the Nine Houses, the "God who became man and man who became God." It's never entirely explained what this means to them, but it's clearly intended to riff on Jesus, the 'Word made flesh' (John 1:14), "born in the likeness of men" (Philippians 2:7).
But here's the thing if you're going to be a Catholic-flavoured god: Catholicism has some quite specific terminology for leveling up in terms of heavenly power.
Jesus, who is God, goes up to heaven after the resurrection. This is described as his "ascension" - it's an active process. He is ascending, going to his heavenly throne. He can do that, because he's God. He *is* the rules of the universe and metaphysics. If he wants to fly up into the sky and transcend into another dimension, he can do that, because he's God.
But there are three other people who are understood to have gone up to heaven bodily: Jesus' mum Mary, and the prophets Elijah and Enoch - for all three of them, this is described as their "assumption": it's a passive process, which they aren't doing under their own steam, it's being done by God. In art, this has historically been depicted by showing them being propelled skywards by a writhing mass of cherubs.
So let's get back to Jod.
You know, the man who became god, etc etc etc? The one who resurrected his Lyctors who then "spread his assumption across the blackness of space"?
Either John wasn't paying quite enough attention when going through Catholicism for Dummies or Teacher is being a bit sly here.
So this is a nod, right at the beginning, to the fact that John isn't actually the metaphysical power of the universe that he claims to be.
