We all know how Han asked Luke to run away with him and Chewie before the destruction of the Death Star 1.0, we also know that Luke said 'no' and ran off with the Rebels to take down said Death Star. Then of course Han turns the Millenium Falcon around to help said Rebels, and so the rest is history...

But just say Luke said 'yes' instead of 'no'. Just say Luke ran off with Han and Chewie and never stayed behind to help Leia and the Rebels.

What if Luke got to see worlds of green and blue? What if Han and Luke and Chewbacca explored the galaxy together without the problems of fighting The Empire?

What if one single word changed an entire galaxy?

(Skysolo AU I guess? Or is it cannon divergence? Yeah, cannon divergence.)
