is there any information on what they were originally going to use as Abeloth's backstory / origin before merging her in with the Mortis Gods?
My guess would be a connection to the gods of the Yuuzhan Vong. Maybe she would have been revealed to be a member of their pantheon.
I'd never considered that, but the idea that the big reveal of Fate of the Jedi might have been "The Yuuzhan Vong deities were indeed actual gods, and were getting revenge on the Jedi for defeating the Children of Yun-Yuuzhan in the style of a Greek tragedy" is a way crazier idea than what we got, in all the right ways.
I just figured Abeloth came about because of the author's obsession with tentacles and bringing unwanted stuff into the Star Wars universe.
Denning said that he always intended Abeloth to be a corrupted servant of the Celestials. I suspect drinking from the font and bathing in the pool were always part of her origin, but I wonder what "servant of the Celestials" would have meant without Mortis. I'd have loved this if they also revealed the Vong gods and the Sith gods were one and the same.
I never liked the notion so recently introduced that the Vong gods were tied to beings within the GFFA-the new jedi order makes the origin of the vong gods pretty clear-they are distorted cultural memories or echoes of Yuuzhan'tar and the Ur-Vong's Edenic and symbiotic relationship with Zonama with the vong gods taking on aspects on their "mother".
That's pretty interesting, actually - the Mortis arc thus conveniently allowed him to put faces on precisely which Celestials she served.
it just seemed to be building up to something, ever since the Correlian trilogy and Centerpoint. Then we get the mention of the Celestials in the Swarm War (i think).
I thought at the time there was some deeper meaning to Ahsoka being left out of the story of the Mortis discovery in Apocalypse (or whatever book it was), like her eventual fate was going to be wiped out from history by an Act of Mortis or something like that. Nowadays, I think Denning just didn't want to deal with referring to her when it wasn't clear what her end story would be. Though thinking about it now, that's not too far removed from the time travel stuff with her in Rebels. So maybe the seed of that did get planted in Filoni's head from talking about her with Denning.
Funny enough I feel that new canon might go an Ashoka centric route with Mortis stuff if it's touched on again considering what happens in Rebels.
Well a Treaty of Anaxes was mentioned in the Legacy comics that said, the treaty was to have the Galactic Alliance and the Fel Empire defend each other in case of attacks such as by the Yuuzhan Vong. so another Vong War seems logical at some point.
There wouldn't have been another Vong war in the eighty year timeframe between Crucible and Legacy. At least, it's extremely implausible. If such a thing did occur-why don't characters ever refer to the "second Vong war" or something to differentiate it from the first? Also the Vong were mostly disarmed and sent to Zonama. And I get the impression they did indeed change or attempt to change their society. And the Vong that did not go to Zonama were scattered throughout the Galaxy and weren't in any way capable of waging a second war.
