SOS
An SOS was a form of distress signal. Days after the Battle of Endor, the Alliance to Restore the Republic received such a distress message from Wilek Nereus, the Imperial governor of the planet Bakura, pleading for assistance from Emperor Palpatine to repel an invasion from the Ssi-ruuvi Imperium.
