I Don't Understand Warbreaker's Ending

I don't know what it is about Warbreaker, but half a year after I finished the book and the entire cosmere later, and I still just don't understand the ending. How are Breaths passed down between the God Kings? What happened to the other God Kings, since I think it mentioned somewhere that they aren't actually dead? What was Denth doing the whole time? Why are the Five Scholars only doing things now, after 300 years? I know that a lot of this is explained, but it just feels like all of those explanations flew way over my head, which is weird, since I don't tend to have trouble understanding plot elements that aren't outright stated but revealed through context clues. Is this just a me thing, or does anyone else also feel this way?

Don't get me wrong, I still absolutely love Warbreaker, but I just hardly understood what was going on in the ending.
