The only thing more powerful than a Goddess in fictional work, is her writer that wants to see her knocked down a peg.
So the intentions of the writer, are much more important to the direction of the story, than the fictional details of the setting within that story.
And given that the writer has thus far, just... completely ignored my inquiry at all, both times I've asked about, sorta suggest to me that if you're signing up for servicing aforementioned Succubus Mistress, what you are instead signing yourself up for is a big heaping plate of disappointment. Which, you know, as said.. huge bummer, but whatcha gonna do?
