Sethra, from _Issola_, pg 37 (hardcover): "[...] I cannot, in my own mind, imagine the cataclysm of the moment when [the Great Sea] came into being, that instant when for the first time the Unknowable took form." She goes on to say that the existence of the Unknowable, now knowable, meant there would eventually be a goddess of elder sorcery, and a Serioli who made Great Weapons embodying it, and a human who built the Orb. Also that the J want the power thus represented. Clearly reasonable evidence that the GS was the first amorphia, and following Alexx's placement of these events at "~300,000 BI??" would mean recent amorphia, so Jon's claim earlier is sensible, and I was overly skeptical. Note however that Sethra doesn't present any evidence that the GS was the first amorphia - all her consequences follow regardless. Maybe her point is really that stable amorphia changed things. The Serioli may have been making small evanescent amounts of contained amorphia since before the J showed up (30M BI, Alexx hazards) for all she knows. I think it's likely that the J had some sense that Dragaera was an environment that could support amorphia, as they seem to have had a lab experimenting in something that on being sabotaged made amorphia, and they may have been responsible for the amorphia-related genetics of the Kieron line. Maybe they were also making small evanescent amounts of the stuff. As a particle physicist, it seems unlikely to me that something might exist in one place only, as Sethra says - but if so, then there's the question of whether the stuff exists in the vacuum, which is full of matter-antimatter pairs of everything. And then there are the issues of the spectrum of stuff produced in the Big Bang and from Hawking radiation (if either is physical in the Dragaeran multiverse). Note that the J were able to make a river of amorphia elsewhere, to Sethra's great astonishment, so she may be overrepresenting her understanding of the issue to Vlad. And Vlad was able (I think) to produce amorphia there as well. Maybe Dragaera isn't so special in this sense. As an aside, either Sethra is lapsing into Paarfi-style with "I cannot, in my own mind, imagine", or she does imagining in others' minds.
