Was Sadeas ever affected directly by Odium or an Unmade, not counting the Thrill?
NOT counting the Thrill, ok uhhhhm. There are affects of other unmade around, and Odium's effect - direct effect? I'm going to say, no, maybe some indirect effects.
What about Roshone?
Uhhhm, no. The Thrill is the main thing that is getting the Alethi so, I mean, there are others around, but it's not as obvious with that as with other things.
