First, Kurald Emurlahn. I don't have a page number, but right before Kamist Reloe's assassins leave to find the Whirlwind Goddess, Febryl says that the the Soletaken Ritual of the First Human Empire was responsible for the fracturing of KE. Why would this be? I certainly want to know more about the ritual, but I hadn't noticed this statement until a reread last night.
Second, the Deragoth. I had thought that it went down as follows.
a) Paran frees the two Hounds of Shadow from the sword, and they jump through the gate to Kurald Galain.

c) Two Deragoth coinidentally show up at Raraku.
When the two Hounds of Shadow leapt into KG, I think they ceased becoming reflections, and merged with their original source (Deragoth). There seems to be a theme that KE is some kind of derivative of the interaction between KG and KT (light + dark = shadow?). But why would the Shadow Hounds be thus bound in KE? Onrack or Trull mention that creating a physical likeness of a god renders it powerless, or something like that. Who imprisoned the Deragoth by creating the giant statues?
I sense a major point here, but I can't get my head around it.
If the fracturing of KE was caused by the Soletaken Ritual, and Dissembelackis had a pact with the Deragoth, this might all be related. Perhaps the T'lan Imass didn't just slaughter the First Empire, but also conquered the Deragoth by freezing them in a fragment of KE. But then where did the Hounds of Shadow come from? Does freezing an elder being in a derivative warren automatically create a weaker reflection of the being?
Finally, if an Azath House appeared in Darujhistan to counter Raest, why the hell didn't one appear to counter the massive power convergence that arose in Raraku at the end of HoC? Maybe there was so much conflicting power that the Azath (whomever they are) just knew that things would cancel out. How far from the heart of Raraku is Tremorlor, anyway?
Argh. No, I'm not using any drugs or alcohol right now.
