Hidden Jedi Temple
... or, Travels with my Uncle. XD

So, in a newly released SW novel, we learn that, just a few years before TFA, Luke was looking for the first Jedi temple with his nephew Ben in tow. And here we all thought Luke had been missing, and Ben Kylo, for a decade. In addition, the novel doesn't mention Rey at all (and in the review of the novel I read, the reviewer expressed their regret that "that Jenny Dolfen scene" now never happened. =O) I'm friggin' pop culture!!

I probably will take this further. :)
