In [[Yu-Gi-Oh! GX - Episode 097|episode 97]], [[Maximillion Pegasus|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 "[[Destiny Hero - Plasma|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 [[Yu-Gi-Oh! GX - Episode 100|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 is quickly overwhelmed by the despite help from [[Sartorius]] Good personality [[The Light of Destruction]]unleashes [[Arcana Force EX The Light Ruler]] to defeat Aster.
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 Light of Destruction is sealed away forever.
