Society of Light The Society of Light ( 光の結社 , " Hikari no Kessha " ) is a cult in " Yu - Gi - Oh ! GX " , led by Sartorius , who was influenced by the Light of Destruction ( 破滅の光 , " Hametsu no Hikari " ) . They serve as the central antagonists of the series ' second arc , intent on the planet ' s destruction . Design . The attire for members of the Society of Light is similar to that of the Obelisk Blue uniform for males and females . The only difference is the alteration in colors from royal blue and white design to white and lavender design . History . On the surface , the agenda of Sartorius and his organization appears to be world domination starting with Duel Academy by expanding their syndicate , but Sartorius evidently wishes to put his stalled fate back into motion through the powers of Jaden and Aster . His ultimate goal is to put an end to the " age of darkness " by destroying the planet to restore balance to its imperfect state , and create the world or on a greater scale , the universe anew . Members are brainwashed into the Society ' s fold by losing to Sartorius or one of his representatives in a Duel , using Sartorius ' own mystical powers of fate - prediction and his talent for pushing an opponent ' s buttons to make them lose faith in their own lives and convince them that joining the Society is a much more preferable alternative . Duelists reined into the Society in this manner are usually very devoted to its goals and have a deep obsession with the color white because of the fact that they were brainwashed upon their defeat . Essentially , the truth of their obedience is clouded behind the Society , Sartorius , and the lies they are told ; they often reject outright or even forget parts of their pre - Society past the more they ' re in it and ex - members often can ' t remember anything that they did in the Society beyond the Duel that forced them into it after they ' re broken free . Only those with incredibly strong wills or those under the influence of outside forces can escape the Society ' s hold and at its basic level Sartorius ' mind control is not necessarily absolute ; with some Duelists , aspects of their old personalities can shine through on occasion although this can be rectified should Sartorius exercise more strength in using his powers . The signature card used by the highest ranking members is " White Veil " , which represents their belief in the " light of truth . " Upon joining , most members become openly obnoxious and arrogant , convinced that their force is unstoppable and that Society members are more important . Shortly after the second year begins , Chazz is defeated by Sartorius and coerced into joining the organization . From then on , he serves as means of converting the top Obelisk Blue students and by episode 70 most of have been defeated and have " seen the light . " In protest , Alexis Duels with Chazz only to become a member herself upon her loss . During the field trip to Domino City Sartorius confronts Seto Kaiba and requests the use of KaibaLand . Once his request is granted , Jaden and Aster are lured into the virtual world by his sister , Sarina . Upon learning of their victory , Sartorius suddenly becomes more interested in leading them towards their respective dooms . As his sister alludes ( states explicitly in the Japanese version ) , the universe ' s threat lies in the Wheel of Fate ( Wheel of Fortune ) , a metaphor for both Sartorius ' destiny and the weapon of mass destruction he would later obtain . In episode 82 , Chazz begins recruiting top students of Ra Yellow for the Society of Light which leads Bastion to challenge Sartorius to a Duel . Sartorius sends Chazz in place of himself and Bastion allows himself to be defeated in order to become a member of the organization . Two episodes later , under Sartorius ' request , Chancellor Sheppard invites Prince Ojin of the Misgarth kingdom to participate in the Genex Tournament . Sartorius thus acquires the control switch for the most dangerous mind - control satellite known to the world ( S . O . R . A . in the Japanese version ; ソーラ , " Sōra " ) , along with the two keys for its activation by defeating him in a Duel . To prevent his evil side from instigating world destruction , Sartorius approaches Jaden and Aster and gives them the keys . In response , his evil personality assigns more Dueling assassins to win the keys back but is unsuccessful . In episode 97 , Pegasus reveals the origins of the Society of Light . In the dark recesses of space , several hundreds of millions of years ago , a white hole released the dark matter of a black hole as well as a great energy known as the Surge of Light ( 光の波動 , " Hikari no Hadō " ) , which bombarded the Earth throughout the course of history , propagating wars , disasters , crimes , and dictatorships . The " Ultimate D - Card " created by Aster ' s father was corrupted by such energy and caused both Sartorius and Pro League king , The D , to develop split personalities . Because of its infectious properties that rival the powers of the Egyptian God Card s and Sacred Beast Card s , as well as his concern that Aster will be harmed should it ever arrive in his hands , Pegasus wishes to seal the card away before it brings an end to the world . In episode 100 Aster breaks into Obelisk Blue looking for Sartorius and finds him waiting in the Society of Light ' s private Duel field , the Great White Temple ( ホワイト大神殿 , " Howaito Dai Shinden " ) . Intending to keep his promise of saving Sartorius from his destiny of becoming a destroyer , Aster considers relinquishing his key to Misgarth ' s satellite but is persuaded by Jaden to do otherwise . Recognizing the present Sartorius as an impostor posing as his dearest friend , he wagers the key in a Duel but despite help from Sartorius Good personality The Light of Destruction unleashes " Arcana Force EX - The Light Ruler " to end the Duel . Following Aster ' s defeat Jaden takes his place to determine the fate of the world by Dueling Sartorius . While the battle is taking place , Chazz successfully reverts all of the Society of Light ' s members back to their former selves with the assistance of a group of Obelisk Blue students thereby releasing Duel Academy from the Society ' s grip . Having obtained both keys due to a blunder on Jaden ' s part , Sartorius takes complete control of Ojin and orders him to the fire the mind - control satellite . Although it does cause some damage to the planet ' s surface , Sarina hacks into the satellite ' s programming to disable it allowing both " Elemental Hero Neos " and Tyranno Hassleberry to destroy the satellite . Shortly afterward , Jaden defeats Sartorius and the portion of The Light of Destruction possessing Sartorius is sealed away forever . Named Members . The Light Brigade . The Light Brigade , known as the Four Monarchs in the Japanese version , is a group of assassins in Sarina ' s service . All four members Decks are centered around a " Monarch " .
