One possible plotline could be Percy having to face some new and terrifying monsters sent by Nyx's enemies. Since Nyx is a powerful figure, there would be many who oppose her, and Percy, as her champion, would be in the line of fire.
Perhaps a plot where Percy has to journey to the darkest corners of the Underworld, which are under Nyx's domain.

In this fanfiction, it could be that the normal rules of the Percy Jackson universe are bent a bit because of Nyx's influence.
