Return-to-Coruscant was a transmission activated by Darth Vader during Operation: Knightfall through the Jedi beacon. The code would alert Jedi that the Clone Wars were over, and to return to the Jedi Temple on Coruscant to await further instructions. In truth, the code was a plot to draw in and kill any Jedi that survived Order 66. The code would be deactivated by Obi-Wan Kenobi and Yoda during their infiltration of the temple.
