Cyborrea was a high - gravity planet that was located within the Cyborrea system of the galaxy ' s Hutt Space region and lay on the hyperlane called the Sisar Run , which connected it to the worlds of Dirha and Sionia . Cyborrea was home to aggressive dog - like creatures known both as neks and Cyborrean Battle Dogs , which were bred and trained on the planet and ensured a wide - spread reputation for their homeworld . History . Cyborrea constituted a part of the Hutt Empire around the year 25 , 100 BBY , when members of Cyborrea ' s native Cyborrean species served as heavy infantry in the armies of the Hutt military commander Kossak Inijic Ar ' durv during the Second Battle of Vontor between Kossak ' s forces and those of the Tionese warlord Xim . More than thirteen millennia later Cyborrea was no longer a part of the Hutt Space , yet during the Galactic Republic ' s Third Crusade against the Hutts in 11 , 939 BBY the Republic still launched a battle - fleet toward the planet . By the year 5000 BBY , the territory surrounding Cyborrea had returned under the control of the Hutts . At some point before the conflict known as the Freedon Nadd Uprising that happened in 3998 BBY , members of the Republic Army ' s elite rocket - jumper unit were sent on a mission to Cyborrea . During their assignment , the elite soldiers had to drop to the planet ' s surface with rocket packs from an altitude of sixteen miles . When the Galactic War broke out between the Republic and the resurgent Sith Empire in the year 3641 BBY , the renegade Sith Lords known as the Dread Masters used a Force phantom to destroy entire fleets over Cyborrea . The population of Cyborrea around the year 25 ABY ranged from 100 million to 500 million . At some point between 26 ABY and 27 ABY the Cyborrea system was attacked by the military forces of the extra - galactic Yuuzhan Vong species during their conquest of the galaxy , and the star system was held under the control of those invaders until at least 27 ABY . By the time of the Second Galactic Civil War that began in 40 ABY , the Hutts had regained control over the region of space containing Cyborrea , and it remained so by the year 137 ABY .
