All fair points, but I'd argue that something with strong enough cultural relevance would be similar to santa in that it could become a fable. The JFK assassination and other conspiracy theories like Area 51 having aliens, for example. There are plenty of books on them that could lend to the setting of "storybooks". I've got a few ideas in mind but I'm sort of saving them in case I end up wanting to app them, heh.

Seems to be kinda stretching the definition of "story book" there, but sure? I mean, it's really down to the GM definition here. I'm sticking with things that are a little more certain and such.
You've also got to remember that picking anything modern basically guarantees it can't be stronger than a Fable unless it's really lucky, like Santa, which is plenty fine sure, but the limitation is there.
