Mystery Box

... the librarian took the rogue author's Pen away forever, and kicked her out of the library. So at least new stories wouldn't be written.

Uhhh... just to be clear... you're not implying that they purge Miss Tery Box's Mind, are you? Because... that's how it reads.

Also, you want us to be the villain but that way often leads to death, unless we switch the narrative. Gotta turn this into a story where the "main character" is a tragic hero with flaws who dies at the end, like a certain playwright might. Or, flip that script and turn it into a story where the protagonist is actually the antagonist that gets their comeuppance. I mean, stories are filled with the fall of tyrants... Some of whom happened to be the main character.

I think Miss Tery Box had... good intentions with what she did though. Obviously, non-ideal implementation... but this Higher-Thought-Process might understand the why though, and... not necessarily disagree. Or maybe its just the Slimerat Poison.
