The Battle of Zorabos was the first major engagement of the Ssi-ruuvi Incursion. Zorabos had transmitted a request for help to the Prime Fleet when it came under sudden attack by the Ssi-ruuvi Imperium. After a brief debate, Tariun Sakaros sent Sorri to face the invaders, while keeping part of the fleet with him to continue the prosecution of the Vagaari War. Vem led a ground attack to wipe out the Ssi-ruuk and entechment-powered battle droids. It was only after discovering the entechment rigs that the Empire fully understood the details of the threat posed by the Ssi-ruuk.
