From Introduction: "Horning In" is a Star Wars Roleplaying Game adventure for four 10th-level heroes of any persuasion. As written, the adventure’s set in the Rebellion era, but it can be modified easily to work in any other era of play as well. Although the villain of the story flies a ship described in Starships of the Galaxy and the scenario calls for a capital ship that also could be taken from the pages of that accessory, the book isn’t required to run this adventure.
