Warbreaker - I Need You, You Shall Return and Be Special

Theoretically, we will learn more about the five scholars and more about nightblood in the warbreaker sequel. And as of right now, I just have so many questions about how this came about. Were the iridescent tones and the religion the same as we see them in warbreaker where all of the returned gods are just lounging around? Or were they set aside more to be a tool of the God or the shard?"
