I was able to rescue an old overview I did, roughly based on Athas.org but modified as I required my Sorcerer-Monarchs to be epic casters and manifesters (they got quite a few more levels out of it). I had writeups I may be able to salvage as I get further along in the recovery but here’s a draft I had:

I don’t think this was the final document I had created, I’m pretty sure I had used more PRCs, especially for the Psion levels, but it would give you an idea. Also note I had several of the old Champions return (as well as some other characters).
Andropinis was still in the Black, Borys had returned as a Wrath started bringing the few survivors of Ur Draxa together and was looking to ressurect himself, Cielbia (Sielba’s twin sister) was trapped south of the Dead Lands and trying to get free, Dregoth’s spell failed but returned him to life and completed his transformation, Kalak was potentially kicking around/being resurrected, Kalid-Ma was being reconstituted via the orbs first as a human and then working her way through the dragon transformation, Sacha had finally been killed and his his Tower Bound ability kicked in so he was trying to figure out what happened to Rajaat, Sielba’s mind was trapped in her sister’s body and looking to escape into a body of her own, Abalach-Re had reincarnated but lost her dragon level and was trying to figure out how to retake Raam or if she should cut her losses.
