Sor-Sull II was a Sullustan EF76 Nebulon-B escort frigate that carried some of Sullustan delegation to a diplomatic meeting between the Sullustans and the Alliance to Restore the Republic near Sullust during Operation Strike Fear. The meeting was interrupted by the arrival of the Imperial-class Star Destroyer Invincible. Hamo Blastwell and Keyan Farlander, flying R-22 Spearheads, held off the Imperial fighters until the meeting was concluded and all ships fled into hyperspace.
