Quilan Vos... Alternate Vader?
Or maybe Kraytt takes Vader's place?
In fact, Anakin's path starts when Shmi dies, soz she doesn't... As well, he doesn't give in to his emotions for Padme, so no Luke and Leia... Han is now a real scruffy nerf herder... but Chewy dies on Kashykk against order 66. The Rebels don't exist, and the sith rule the galaxy forever.
