Imagine a path. The path goes as far as the eye can see, and branches off in an infinite number of directions. Each branch has more branches, and at the end of each one is a portal. To different times, different planets.
You can hear it. Whispers from other times. Some of the voices were achingly familiar. I heard Obi-wan, I know I did. And I felt other whispers in the Force.
In the dream I didn't recognize most of them, but knowing what I know, I'm positive some were Luke, and Rey. Another voice said a name, Revan, who I've only ever read about in the Jedi libraries.
