Sartorius is a mysterious figure introduced in the second year who is Aster's manager, and the leader of the Society of Light. On the surface, the aim of Sartorius and his organization appears to be world domination starting with Duel Academy via expansion of their syndicate, but the man's gravest concerns lie in putting his stalled Wheel of Fate back into motion through the powers of Jaden and his childhood friend, Aster, as means of escaping the destructive future that destiny had set for him. Although this goal was always on his mind, he was pushed towards an ultimate motive of eradicating the "age of darkness" that had befallen the planet. It was his task to blanket the globe in light, destroy it, and kill all its inhabitants to restore balance to its imperfect state and create the world or on a greater scale, the universe, anew.
Fearing the corrupt "Ultimate Destiny Card," the to-be-Pro League king The D sought the kind and caring Sartorius for guidance, but accidentally imbued him with the will of a dangerous alien energy known as the Dark Light / Light of Destruction 「光の波動 / 破滅の光 Hikari no Hadō / Hametsu no Hikari」 known by the latter name Surge of Light or Light of Ruin 「破滅の光, Hametsu no Hikari」 in the Japanese version, which had taken up residence in the card. Like it had in The D, it provoked an onset of dissociative identity disorder, forcing Sartorius to contend with a dominant evil persona. The card would disappear from his possession shortly thereafter.
