...can Radiants even swear oaths even more? Would Taravangian be willing to give power to his enemies? Cultivation is gone so she can't accept the Words. And Syl (and the Heralds) can't cause she's stuck in therapy time. And the Sibling is asleep. Guess it depends if Taravangian has to in order to not cause conflict with the Shard of Honor
If we leave Tetribution (haha) aside, I think the only one left who could theoretically accept oaths is the Nightwatcher!!?? And now that there's an endless night stretching across most of Roshar I imagine she's going to get more powerful. Plus, she's notably obsessed with trying to understand people. Should be fun 👀
The idea of Retribution accepting oaths is also fascinating! If Taravangian refuses to accept oaths, that would likely really offend Honor's power, so I doubt he'd do that. Plus he wants more warriors for his off-world conquests, so I imagine he might try to win them over, or failing that, try to manipulate them into serving him.
OH I forgot that there was a little child-shaped Honor out there in the Spiritual realm. Is he part of Retribution now or is he still hanging out in the Spiritual Realm? My guess is that he's part of Retribution and still at least somewhat self aware, remembering Dalinar's lesson, watching Taravangian and learning. Might he be able to accept oaths without Taravangian?
