Eren was Sansara Sage's legacy holder.
He was well aware that the knowledge of space-element runes and valuable ranking resources within Sansara World 2.0 were not the sole legacy left by Sansara Sage. The isolated dimension itself was one of the Sage's most precious offerings to his successor.
It was now the inheritor's responsibility to uncover the true purpose behind Sansara World 2.0. And to understand why Lin Lehan had bestowed complete ownership of this isolated dimension upon his chosen one.
Ideas began to form in Eren's mind, theories related to how Sage rankers, including Sansara Sage, were able to traverse beyond the boundaries of Anfang despite the world-isolating array that prohibited spatial teleportation outside its confines.
The timing couldn't have been better for Eren to pose this question to Maya. With a smile, she responded by asking Eren a question of her own.
