I have no problem with the general interpretation of HB and EN, with the obvious reference to a Christian apocalypse with one and the capstone being about the series' Big Bad.
But Stars and Stones... I'm not sure where I fall with that one.
HB seems to be referencing some sound or signal that will ring when hell breaks loose (although which hell/Hel might be up for debate). EN seems to be a celestial event that Mab references once, tying it to her interests (Outsiders), and is one the Wamps like to invoke, who have at least one tie to Outsiders.
But S&S seems to reference... stars and planets. Or asteroids crashing down. Or fire and brimstone falling from the sky after volcanic eruptions. Or something else.
I'm not sure what that specifically has to do with the Fomor, or Ragnarok, or any other pantheon. Which is a problem.
I feel like there is likely a more direct corollary between the title and the events.
Most likely it's a reference to parts of the Biblical Apocalypse crossed with two or 3 major things mentioned as 'stone',(which could all end up being one and the same sources... the stars or the core of them, their identity, ect.) Mostly though the idea of stars falling as 'stones'.. but let's see, we have MW's traveling stone, the 5 stars on Lady Nights neck in CH, the stone coffins surrounding MW's cottage(some of which have broken and crumbled), the stone table(which just might be our 'stone' for star ratio?) Starborn themselves of course...
Mostly the problem defining it is it's a definite mash up by JB for his own apocalyptic story... But I maintain the idea of fallen star particle/identities as the manifestation of his own biblical crossover..
And realized writing it the answer is likely simple... I keep looking at the replaying of the same story but I forgot the current rendition will have one of it's own despite being tied to TWG's version and the outsider/undead versions... It will be about the rise of the new order of mythos specifically, about the defining of the current Generation, the big reveal, the empire striking back, starborn demystified, rise of the new pantheon, ect.
It makes total sense to give definition to the overarc their... on a thematic level of course, but i'd bet dollars to donuts now that I've thought of it. It's the apocalypse created in the NOW.
