The marauders known as the Nihil have stranded hundreds of worlds in a part of the galaxy known as the Occlusion Zone. With communications blocked and ships unable to enter, Jedi Knights Keeve Trennis and Elzar Mann have turned to centuries-old technology to send messages of hope into the Zone. The messages they receive in return — from Jedi younglings, Padawans, and Knights, and more — will set the stage for the final battle between the noble Jedi and the nefarious Nihil.
