First Battle of Calamari
the Emperor Palpatine, reborn following the Battle of Endor into a new clone, was just beginning to stretch his new power. He called upon his weapons experts, who delivered a new superweapon, the World Devastators. He launched his initial attack at the ocean world of Calamari. The Mon Calamari - former Imperial slaves - had built many of the best starships currently used by the New Republic, and a strike at the New Republic's main shipyards would help turn the tide and get the Empire back on its feet. The Emperor's plan, however, was foiled by Luke Skywalker and Artoo-Detoo. Luke, under the Emperor's Dark Side influence, retained his allegiance to the New Republic, and fed the World Devastator's' master control codes to Artoo-Detoo, who used them to reprogram the superweapons. Instead of consuming Mon Calamari cities for raw materials, Artoo programmed them to consume each other. The Imperial fleet was decimated by the counter-attack from the World Devastators, and was forced to retreat.
