The Diplomatic Summit at Sullust occurred in the initial period of the Galactic Civil War. Following the Alliance to Restore the Republic's rescue of a Sullustan tech staff by a fortnight, the leaders of the Sullustan resistance movement consented to begin diplomatic discussions on the planet of Sullust to deliberate joining the Alliance. Nevertheless, the Imperial Star Destroyer called the Invincible assaulted the summit, as part of Operation Strike Fear. Hamo Blastwell and Keyan Farlander, Rebel pilots who were flying R-22 Spearheads, stalled the Imperial starfighters until the meeting finished and every ship escaped into hyperspace.
