Ok, so I finally get CotCT #12 and SD read through them once already and going through a second time right now.
So, as I am reading I see that Earthfall was caused by an Aboleth weapon that pulled a star down and basically nuked the Azlanti.
Then I remember that Zon-Kuthon agree to be bound into the Plane of Shadow for as long as the sun hung in the sky. In return he would recieve the first shadow when he was freed.
So the Aboleth apocolypse freed Zon-Kuthon. Could it be that the entity that possessed Dou-Bral and became Zon-Kuthon could be an immense aboleth or something. It is something that just "clicks" in my mind.
It's the little details like this that make my brain kick into overdrive. I may never know if I am even close on this but it feels right and I believe it will be how my Golarian is ran.
Does anyone else see this like I do?
