Gravlex Med / Legends Gravlex Med was a terrestrial planet in the Outer Rim Territories . With an above - average gravity , the planet ' s native species , the Anx , had a stooped stature and other species found the world uninhabitable . Gravlex Med quickly became the heart of Anx Space as the spacefaring species expanded their borders throughout the Raioballo sector . During the reign of the Galactic Empire , Gravlex Med became so polluted by Imperial mismanagement of waste that the world no longer proved suitable for habitation . Description . A temperate world , the surface of the planet was covered in savannas and pitch - dark mountains . The Anx lived in caves systems , emerging to browse on the chiliox tree s of the savannas . Before contact with the Old Republic was established , the Anx developed short - distance interstellar travel , launching their spacecraft with giant cannons . The escape velocity from their homeworld was low enough that the Anx could survive orbital launches in such projectiles . History . An early spacefaring race , the Anx species had built massive cannons from which they launched spacecraft into space for short - distance interstellar travel . Colonizing the surrounding planets in what would come to be known as Anx Space , Gravlex Med became the heart of the society . As an unintended consequence of their journeying , the Anx homeworld was invaded briefly by Shusugaunt conquerors . Driven nearly to extinction by the invaders , the Anx eventually found salvation in their world ' s natural defenses . Unable to survive in the high - gravity ecosystem of Gravlex Med , the Shusugaunt were forced to abandoned their conquests and flee the world . In 5000 BBY , the Galactic Republic discovered the Anx species and accepted them into the Galactic Senate . Quickly assimilating into Republic society and governance , the entire Raioballo sector was represented in the Republic ' s Senate Building on Coruscant by Senator Horox Ryyder during the Chancellery of Finis Valorum . Retiring in 22 BBY on the eve of civil war , Ryyder returned to Gravlex Med and was replaced in the Senate by the planet ' s former President , Zo Howler . Remaining loyal to the Republic throughout the Clone Wars , a conflict between the Republic and the Confederacy of Independent Systems , the planet was protected by the Ninth Army of the Grand Army of the Republic and saw no action during the war . At the end of the war the Republic was replaced by the Galactic Empire and life on Gravlex Med changed forever . Taking control of Gravlex Launchworks , Imperial mismanagement of the hazardous wastes contained in the factories caused the near extinction of the Anx species and drove all survivors off world . As the Galactic Civil War erupted , Gravlex Med was controlled by Imperial forces which called themselves the Pentastar Alignment after the death of Emperor Palpatine in 4 ABY . In 12 ABY Grand Admiral Gilad Pellaeon annexed the Alignment sectors and Gravlex Med and other Anx colonies fell under the control of the greater Imperial Remnant . While under Pellaeon ' s control , the New Republic attempted to disassemble the Imperial flagship " Chimaera " at the orbital shipyards . However , as the New Republic attempted to destroy the starship , insurgents of the Imperial Remnant recaptured the vessel in one of Pellaeon ' s last victories against the Republic . As the Imperial Remnant struggled to maintain a cohesive structure , the Yuuzhan Vong invaded the galaxy and control of Gravlex Med fell to the Yuuzhan Vong empire . After the alien invaders were defeated , the Imperial Remnant took to liberating their former holdings and were able to reunify while the fledgling Galactic Alliance retained control over the Core . Behind the scenes . The " Ultimate Alien Anthology " refers to the world twice as " Gravlex Mex " and wrongly places it in the Mid Rim .
