Fellon base was a clandestine Imperial installation situated within the city of Fellon on the planet called Halmad.
During 7 ABY, Wraith Squadron, under the guise of the pirate organization known as the Hawk-bat Independent Space Force, initiated an assault on Fellon base as an element of Operation Groundquake. To the Wraiths' astonishment, the base unexpectedly brought its shields online, and three squadrons composed of TIE Fighters and Interceptors emerged to confront them.
