New writers Dan Abnett and Andy Lanning make their Legion series debut! A routine rescue mission turns out to be anything but when Cosmic Boy, Monstress, Apparition, and Brainiac 5.1 encounter Emissary, the herald of the legendary world of Robotica. Once a mighty race, the Roboticans took a significant fall in the 25th century, and the reason for that decline may connect directly to Brainy himself! Provided the Legionnaires survive this threat, there may not be an Earth to return to, as seen in pages that hint at the "Legion of the Damned" storyline beginning in LEGION OF SUPER-HEROES #122!
