Yo ' gand Yo ' gand was a legendary Warmaster and the first Supreme Overlord of the Yuuzhan Vong . Biography . Warrior . Yo ' gand was a male member of the Yuuzhan Vong species , a race of previously docile humanoids who had repulsed a machine empire from their ancestral homeworld and subsequently embarked on a centuries long conflict known as the Cremlevian War . Clans and tribes of Yuuzhan Vong battled one another across the galaxy , vying for primacy . Yo ' gand fought in the war , earning the rank of general . He came to be revered as a mighty warrior , fighting rival tribes on the frontlines . Eventually , Yo ' gand became a warmaster , leading the warriors of his clan into battle . There came a moment in the war when the forces of Yo ' gand were competing directly with those of Steng for dominance of the galaxy . A rival warmaster , Steng had situated his forces on the planet Ygziir , where many of the leaders of the most powerful tribe in opposition to Yo ' gand were present . In order to eliminate his enemies , Yo ' gand made use of an innovative tactic . He infiltrated a powerful dovin basal — a Yuuzhan Vong creature capable of manipulating gravity — on to the surface of Ygziir . The dovin basal was subsequently tasked with focusing the planet ' s gravitic field onto a moon of Ygziir . Once the moon had been ensnared by the dovin basal ' s gravitic manipulation , it was dragged down toward Ygziir , impacting directly upon Steng ' s encampment . Ygziir was left a shattered hulk following the collision , which wiped out the opposition leaders . Steng ' s flesh was carefully preserved to be worn by the Supreme Overlords of the Yuuzhan Vong . Yo ' gand was the first to claim the rank officially , although the Cremlevian War had been motivated at times by the pretensions of would - be Supreme Overlords . With the Yuuzhan Vong finally united in the ruins of their galaxy , they embarked on a journey into the Intergalactic Void in such of a new home , traveling aboard planet - sized worldships for millennia . Legacy . Credited with unifying the Yuuzhan Vong , Yo ' gand entered into legend as a skilled and redoubtable warrior . Such was Yo ' gand ' s reputation that the eyes of Yun - Harla , the mysterious Yuuzhan Vong Goddess of Trickery , were said to be the only remaining parts of Yo ' gand . In the minds of Yuuzhan Vong warriors , Yo ' gand represented the pinnacle of martial prowess and achievement . During their millennia long trek across the intergalactic void , the Yuuzhan Vong eventually descended once more into disunity . Rivalry among domains and castes led to the fraying of Yuuzhan Vong society to an extent . Although scouting missions led to the conclusion that a new galaxy had been discovered , the worldships eventually began to deteriorate , leading to further discontentment aboard the worldships . Factions contended and betrayed one another for the favor of Supreme Overlord Quoreal , until Shimrra , the figurehead of Domain Jamaane , usurped and killed Quoreal in 29 BBY . As when Yo ' gand had defeated Steng , unity was restored to the Yuuzhan Vong following the death of Quoreal . The invasion of the galaxy commenced in 25 ABY . Yo ' gand ' s Core was successfully applied by Prefect Da ' Gara during the Yuuzhan Vong War , using it to destroy the planet Sernpidal . Kalarba was also destroyed by the tactic . In the text of Galactic Federation of Free Alliances ' history , compiled millennia after Yo ' gand ' s life , he was described as the Supreme Overlord of the Yuuzhan Vong at the time of his defeat of Steng . Voren Na ' al , the historian who compiled the document , erred in his description , as Yo ' gand was a warmaster during the Cremlevian War , only assuming the position of Supreme Overlord following its denouement . Behind the scenes . Yo ' gand did not receive an individual entry in " The Complete Star Wars Encyclopedia " , published in 2008 , although he was mentioned in the entries for the Cremlevian War , Steng , Ygziir and Yo ' gand ' s Core .
