Dark Empire #1

Six years after Return of the Jedi, the Rebel Alliance has established a New Republic over three-fourths of the galaxy. The surviving Imperial forces are torn by civil war and harassed by rebel attacks. One of these raids ends in disaster: Luke Skywalker and Lando Calrissian are shot down over the former Imperial City. When news reaches Han Solo and Leia Organa, they rush to the rescue (along with Wookiee Chewbacca and droid C-3PO, of course!) But there's something else rushing toward the Imperial City…something that wants Luke.
