   Summary

   Black Hat is satisfied that everything has gone back to normal, if just a little different this time around after all the decades that have passed. But Black Hat knows that the matter of Lux Noir has yet to be satisfied, what with Slate Hat remaining in hiding, just out of reach.

   Dr. Eitrun quietly waits for the right moment, prepared to use any and all means to get what he wants; a way to make use of Black Hat’s species, or to remove their influence from all universes. With Slate Hat now useless to this cause, Eitrun turns his attention to another, more interesting test subject. An eldritch demon with a mate.
