J. Ras-Teker was as 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.
J. Ras-Teker was first mentioned in Smuggler's Run, a short animated comic that retells certain events of Greg Rucka's 2015 novel Smuggler's Run: A Han Solo & Chewbacca Adventure in the form of an in-universe Imperial communiqué. In the comic itself, Commander Beck simply addresses her superior as "Admiral." However, in Rucka's original script for that comic, the communiqué is addressed to "Adm. Ras-Teker, J. - ISB Command, Coruscant."
