Finally beat it.
There seems to be a few errors. Vauclair name drops Ghostwalker, who doesn't appear until 10 years later in 2064. Its possible Feuerschwinge told him about the Dollmakers coming, but that seems really weird.
Vaulclair also says there are 17 Great Dragons. I think there are 20 known, counting the dead ones. I assume the ones he's not counting are Ghostwalker, the Sea Dragon, and Masaru. Ghostwalker because he hadn't jumped out of the Water Gate Rift yet. The Sea Dragon, because no one seems to know about the Sea Dragon, at least until the 60's. And Masaru just became a Great just a few years earlier, so word might not have gotten around yet.
When I talked to Feuerschwinge about Amazonia she name drops Mujaji, who is in Africa, not South America... But maybe Mujaji originally came from South America or Firewing has no idea what I'm talking about when I name drop Amazonia.
I don't think I like any of the endings. I always liked the idea of a horrible toxic dragon plotting to spread her blight across the world with her toxic shaman cult. Also, I thought there was a metaplot about Kaltenstein trying to clean the SOX to save Feuerschwinge, but I guess that might not be the reason as much as Cold Stone just wants to clean up toxic sites; 'cause you know he's a good guy.
There were a lot of rumors of a 4th AI, so APEX doesn't seem implausible. But at any rate Crash 2.0 would have killed him along with all the other AIs, so its not like he's meaningful to the actual SR metaplot.
