[OB] The 10th Unmade?

[Gavi]

Hi all, 

First post! I just finished Oathbringer, and recently reread The Bands of Mourning, and I had a crazy thought. 

Could the entity posing as "Trell" be the 10th unmade? Maybe the Rosharans don't know about the 10th Unmade because it is not on Roshar? 

It is described as a red mist circling Scadrial. People it controls have glowing red eyes, very similar to the effect of the Thrill towards the end of Oathbringer. 

We know there is traffic from Scadrial through Shadesmar (I picked up on the canned food that Shallan et al. were eating). 

Thanks for listening to my theory!

The color red is indicative of one Shard corrupting the Investiture of another, as per this WoB:

Does red in cosmere signify one Shard co-opting or corrupting another Shard's magic?

Brandon Sanderson [PENDING REVIEW]

Yes.

Welcome to the forums!  THat's an interesting theory!  Sadly, Brandon has confirmed that there are not 10 Unmade.

Is the number of Unmade fixed?

Brandon Sanderson (paraphrased)

Yes.

Is it ten, is it ten, is it ten, is it ten, is it ten?

Brandon Sanderson (paraphrased)

Is it ten? No, it's not ten.

Also, does each of the Unmade have a corresponding order of the Knights Radiant?

Brandon Sanderson [PENDING REVIEW]

Eh... Kind of.

XS-Terrain [PENDING REVIEW]

Ok. So there are nine Unmade right, so which one is left out?

Brandon Sanderson [PENDING REVIEW]

Bondsmith. But it's not as one to one, there's some fuzziness in there.
