I did notice the bit about the flames, but concluded that the same as applied to the rest would apply to Koraakan's tail, too - as in, the flames would be passively burning off the scales, layer by layer - which would have lesser effect due to the fact that the One is actually actively growing addition to that part of oneself. 

I actually covered the bit about the limitations of the Weighter's omniscience in the old OoC - namely, there is no "would be" for Koraakan at all, not even in terms of painfully obvious things. (If I picked my teacup up, held it next to myself above the bare floor, and then asked whether it'd hit the floor if I let go of it, it would yield no result whatsoever. That question cannot be answered.) The only way the Six-Eyed God has anything akin to predictions or logical derivations from the events of past or present is through the karakon (which is actually what is being used here, too; also note that during normal bargains, you won't get a karakon's assumptions, you essentially get what could be considered raw data, which incidentally might simply tear your mind apart depending on the type and quantity) - and the karakon, while having access to the knowledge and being immune to simply going insane from it, are otherwise as slow in sorting through it and as capable of making false conclusions as any mortal. (As it is, there is obviously a focus set on what Rilon is thinking.) - Here I will also note that I am writing Nkaa Raakan in a bit more ... humanized way than the One actually is. I could try to give a more apt depiction, I suppose, but it wouldn't read as conveniently...
Am I making sense?

(Removed the bit about Rilon not caring about family ties, though.)
