[OB] Maybe Taln is the Dustbringer?

[Arch he/him]

A relatively popular theory here is that Shalash will end up taking up the oaths of the Dustbringer radiants. While I'm not opposed to this theory the assumption that Shalash will become the dustbringer because of her new hobby of destroyering art seems a bit shallow to me... Instead I think Taln could be our dustbringer and Shalash the stoneward.

I think it makes more sense to look at Ash and Taln's current weeknesses along with the divine attributes that define their potential orders (granted we don't fully understand how some of these apply yet).

First off, the divine attributes associated with the Dustbringers are "Brave and Obedient". Taln is a much different man from who he was before. In addition to his ramblings we now know that he's become a coward.

Quote

The last glimmers of his lucidity had faded. Once, nothing would have kept him from the battlefield when other men died. Today, he had hidden and whimpered during the fighting.

-Chapter 121

I don't think its a stretch to say that him working through his madness (with help from Ash) and finding his courage again is all but garanteed. Him overcoming his fear of battle would and swearing the dustbringer ideals fit well together.

The divine attributes of the Stonewards are "Dependable and Resourceful". Now that the 2 of them have reunited I think its safe assume that Ash will be looking after and essentially babysitting Taln through his madness. As a redemption arc, it'd make sense to have one of the people that abandoned him be his rock in his time of need. This could be the perfect thing to get a stoneward spren's attention. Of course knowing Brandon none of this will be this straight forward, but you get the point.

If it is Taln, then I suspect it will be because he is somehow accessing multiple orders of KR.

I don't really feel the Taln as Dustbringer thing, as I feel like it would require him to bond first and then start acting like it (while we know spren look for those who fit the others, rather than making them fit the order later on), but I like the reasoning for Shalash to become a Stoneward.
