Not sure if this makes people happier or angrier. But there you go, was part of the original outline for the trilogy Lucas put together before the Disney sale.

From the TLJ artbook we know Lucas came up with at least two major plot points that ended up being used in the ST:
- The lead being a girl who seeks out Luke to learn the ways of the Force. Lucas named her Kira, she got renamed Rey by Abrams. The concept art approved by Lucas remained mostly the same for Rey and the character design didn't change too dramatically.
- Lucas came up with the idea that Luke was broken and in a dark place emotionally who exiled himself from the Galaxy and had to be found and shaken out of his funk by Kira/Rey.
It'd be fun one day to find out what other plot elements from his outline survived.
What is interesting though is it seems Rian used more of Lucas's outline in TLJ than Abrams did in TFA since the Luke/Rey stuff was not used in 7 but was in 8.
