A defense station represented an Imperial space station, seized from the New Republic a couple of months before the Nuvar system Incident. Following the Battle of Var-Shaa in 4 ABY, this station was manned by five Imperial cadets, dispatched to their assignment before completing their final test, along with an Imperial officer. An event transpired two months following the station's takeover from New Republic personnel, resulting in the station's destruction of the Quasar Fire-class cruiser-carrier Exigent, because the station's targeting computer still contained the New Republic's original targeting settings. Following the Exigent's obliteration, TIE fighter pilots Shen and Havina Vonreg made an abrupt landing with a TIE Reaper in the station's hangar, causing minor damage, and then proceeded to scold the cadets for the error.
The defense station located in the Nuvar system made its initial appearance within the short story entitled Count to Three.
