J. K. Rowling is watching you from where she waits, eternally in the void between worlds.
This is casting Rowling as some sort of Lovecraftian horror.
"World domination is such an ugly phrase. I prefer to call it world optimisation."
Flash-forward to chapter 6 (6/I prefer to call it world optimisation.). This is arguably the point where the reader is
supposed to realize that the previous quotes are likely to also be
repeated verbatim in later chapters.
Don't panic, Professor McGonagall!
Possible a reference to Hitchhiker's Guide to the Galaxy?
