Sansara World 2.0 was created as a contingency plan by Sansara Sage.
It was a backup replacement to the Sansara World 1.0, and it was better than its predecessor in every way.
However, Sansara Sage's meticulous planning and foresight prevented him from relying on such a contingency plan in the first place, allowing him to organize the departure of his fellow Sages, ensuring their escape from the confines of Anfang. He followed them soon afterward after settling his affair in Anfang.
Before leaving, Sansara Sage had a brief talk with Maya– his daughter. Knowing the importance of preserving Sansara World 2.0, he entrusted its guardianship to Maya, placing the responsibility of finding a worthy successor upon her capable shoulders.
