Strange Substance: Even the Author Must Die

I'm an author. I woke up one day to find a woman calling herself "Wen" trying to kill me. What should I do? Asking online, and it's pretty urgent.

She said that the world of 4216 was just a story I'd written.

She found the source of the anomaly and put an end to the crisis threatening the universe.

Disasters kept descending, all because of me.

So the only answer was to kill the author holding the pen.

Even the author has to die!
