So, one of the things that has never really been explained as far as I can tell, is why Roshar has embodying unintelligent Spren (lifespren, heatspren, etc) when nowhere else in the cosmere has them. We see intelligent spren (i.e. seons) elsewhere but not phenomenon on roshar where all sorts of generalized concepts have visible spren.
So Shinovar does not have any of these kinds of spren as Kaladin notes. And it appears to have foliiage/fauna resembling other planets rather than what we see on Roshar. And the people are shorter and have round/caucasian eyes. So I'm wondering if there is something sort of supernaturally distinct about Shinovar, a kind of enclave that's cosmerically different from Roshar.
