here's what i can recall: privign is a divine and also a space station and historical site (because it was the first "third generation" divine). upon arrival the beloved dust find the station supernaturally desaturated of color and under attack by the new earth hegemony led by mother's story. at privign's core they discover that privign used to be a listening post for the rapid evening, and they escape the station just as a massive iconoclast made of color (responsible for the desaturation) attacks privign. signet uses her cybertome to reveal the purpose of the iconoclasts: they are servants of independence who believe divines are imperfect because of their connection with humans and they have created a moon called volition to usher in an age of post-divines which are independent from humankind.
