I didn't even realize it...

...but necronomicons exist in Equestria!

Now I feel better about my Starlight Glimmer fic!

If you zoom in close enough, we see one labelled "Lovecolt."

Is it "necronomicons" or "necronomica?"

"Condestoga Cannibals"
"Quantum Physics" (suitably in the Black Magic section, snrk)
