Flow walk

Flow walking was the name given by Lumiya to one of Jacen Solo's abilities.

This power allowed him to see things that had happened in the past as though he were there. He used this to see key events in the fall of his grandfather, Anakin Skywalker, and to discover the fate of Raynar Thul.

In one case only, he used this ability to go forward in time, allowing him to communicate with his mother several days later.

This case alerted Luke Skywalker to just how far his abilities had progressed, because he appeared to have fixed the future.
