Time-drifting was an extension of the Aing-Tii ability of flow-walking, where an individual moved along the threads of the Force to travel backward or forward in time. Jacen Solo learnt this technique and revisited the final days of Anakin Skywalker to find out information about his fall to the Dark side. This ability still had its risks; if time-drifters were seen by those they visited, it could create shifts in the flow of time by altering the visited individual's actions.
