So a good read 7/10

I will start with its biggest flaw, this doesn't explain how we get Chaos Black Bolt. It might not even be Black Bolt, and while this could drive him to become this it does not show unlike Ironman(best one so far), and Blade(it was ok). Still as a Black Bolt (Inhuman overall) it was good. Had something like this when the Inhumans were discovered by humans and the Avengers had to see them. So final thoughts is this is a good story, and works well as an Inhuman/Black Bolt one but fails to act as a Darkhold tie-in.
