J. Ras-Teker was a human who served as an admiral in the Imperial Security Bureau (ISB), an agency of the Galactic Empire that ensured the populace and military personnel remained obedient to the government's ideals. In the immediate aftermath of the Battle of Yavin, ISB Senior Commander Alecia Beck answered to Ras-Teker. After failing twice to apprehend Caluan Ematt, a lieutenant in the enemy Rebel Alliance, first on Taanab and then on Cyrkon, Beck addressed a communiqué to Admiral Ras-Teker, who was then staying with the ISB Command on Coruscant, the capital planet of the Empire.
