> What would you call it if the fetish requires no long-term consequences, i.e they don't actually die?

I personally call it writing another story with the same characters :-P

But if we're going with the theme of naming fetishes after the authors who write about them, then the names that come to mind are JestInPieces, Mephistopheles and Poguemahone.
You can look their stories up in the archives (bin.gurochan.ga)
