Retribution and Voidspren

[Nitpicking]

I don't have Wind and Truth with me here, but didn't Retribution say he was going to inhale all the spren? Would that not include the Voidspren?

The Voidspren were saved from being incorporated into Retribution as nothing but a source of Investiture by the Heralds and the Wind. And potentially, partly by the human and Singer freeing of Ba-Ado-Mishram.

How will that affect their attitude in the Back Five?

I am hoping that this will result in the legendary Void Binding becoming something that characters can use. For example, maybe some of the unoathed will be able to bond voidspren, not because they swear oaths but because their dark feelings draw the void to them?

Imagine if Adolin's possible opiate addiction and his struggle with it was all he needed to bond a Voidspren. Using his Voidish powers makes him long for the comfortable release of the drugs, but in return he can sense pain of those connected to him better and thus be a better tactical leader. There is no oath swearing, but every time Adolin relapses into addiction, the power becomes stronger.
