I was reading BoM late last night, and I saw that broadsheet article that's about talking metal tools. 1 random, unsupported idea flashed through my head, which created a crazy theory. Here we go:
This is based on the fact that Warbreaker and Alloy of Law occurred at the same time (roughly)
What Khriss and Nazh are doing on Scadrial is looking for the new worldhopping Vasher, but they somehow lost him and don't know which planet he went to, which is why they are on Scadrial.
And now for the crazy assumption: Type IV BioChromatic Entities share another characteristic with Type I: That they can modify their appearance. My reasoning is this:
Other crazy idea: All BioChromatic entities can modify their appearance
Only the sentient one (Types I and IV) have the willpower to do so
We see Type IIIs changing to look like they're alive, fabrics looking like muscle and the like
So. Khriss and Nazh lost Vasher somehow, and are searching Scadrial by looking for a disguised Nightblood.
There's no evidence for this so far, but I'm interested in what you all think say as you're tearing this apart.
So, thought?
