Since I have no prior knowledge of this 'black ambrosia novel', I can't determine its author. It could be an indie author or a relatively unknown writer. It might also be a new release that hasn't gained much mainstream attention yet.
I'm not sure specifically as I haven't read it. It could be about a unique and mysterious story perhaps involving some sort of special or dark 'ambrosia' which might be a metaphor for something in the plot.
The changeling queen is surely a central figure. She might have unique abilities as a changeling that are explored in the fanfic. There could be other characters such as a wizard or a warrior who cross paths with the queen due to the allure of the ambrosia. Their interactions with the queen would shape the story and their own character arcs.
In Ambrosia Percy Jackson fanfiction, one interesting idea could be new uses of ambrosia. For example, it might be used to heal not just physical wounds but also emotional traumas. Some fanfictions may explore how different characters react to ambrosia in unique ways. Like a new demigod who has never tasted it before might have a very different experience compared to Percy.
It also serves as a connection to the gods. In fanfiction, the way a character consumes or interacts with ambrosia might symbolize their relationship with the divine. For instance, if a character is hesitant to eat ambrosia, it could show their distrust or fear of the gods who provided it.
Well, one interesting aspect could be the unique world - building. The concept of a changeling queen is likely to bring in a lot of mystery and magic. And the 'ambrosia' might be a key element in the story, perhaps having special powers or significance. It could also be interesting to see how the characters interact within this fanfic setting.
The following are some recommendations for dark novels: "My Princess Has Fallen": This novel was a modern fantasy novel.

These novels were all dark works that could satisfy the readers 'preference for dark plots.
If we consider a common understanding, 'shaft' can refer to different things like a long, narrow part or a passage. In some novels, if there is a description of a shaft as black, it might be for creating a certain atmosphere, perhaps a sense of mystery or gloom. However, again, without knowing the particular novel, it's just speculation.
