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.
Sansara Sage's unparalleled success in safely transporting Rankers out of Anfang was a testament to his unparalleled mastery and ingenuity. Despite the sacrifices and trials endured in his experiments, he achieved what seemed impossible—sending not only himself but also his Sage companions to other worlds unscathed. It appeared as though traversing the demonic plane was as effortless as drawing breath, but the truth was far more complex and perilous than it seemed.
Sansara Sage's experiments related to demonic planes. If they ever came to light, Maya was sure that the masses of Edinburgh would stop seeing him as a talented genius and label him as an evil man.
Of course, Sansara Sage did not recklessly venture into the demonic plane either.
He conducted meticulous experiments and sent numerous test subjects as harbingers into its treacherous depths. In the face of the unknown, he devised the space-element runes, acting as metaphorical bungee cords, to aid those who strayed too far and risked losing their way back. He had invented these space-element runes to expedite his research and minimize the risks of getting lost in the demonic plane.
However, since the demonic plane did not adhere to the same principles as the real world, the space-element runes did not work all the time. While the success rate of saving Sansara Sage's pawns was only fifty percent, these runes proved indispensable in his experiments pertaining to the demonic plane.
Notably, the demonic plane Sage Lehan explored and documented was none other than the realm of gluttony, ruled by the enigmatic Demon Prince known as Beelzebub. The presence of Beelzebub's Altar safely kept within Sansara World 1.0 facilitated Sansara Sage's endeavor, granting him easier access to this plane governed by the powerful Demon Prince.
Only now did Eren grasp the true significance of JJ Edgar's desire to possess Sansara World 1.0. The Sage half-blood must have realized that the creation of Sansara Sage held the key to breaking free from the constraints of Anfang and venturing into uncharted realms.
During the Edinnica Arena incident, it became apparent that Edgar had a valid motive for seeking Sansara Sage's creation. He, along with other half-bloods who had suffered unjust treatment in Anfang, envisioned using Sansara World 1.0 as a means to escape the confines of their oppressive world and seek refuge in another realm.
Labh Salem, a world where discrimination was less prevalent, emerged as a promising destination. Their intrusion into the capital of Edinburgh was driven by this desperate plan, hoping to seize the opportunity that Sansara World 1.0 presented.
When Eren blew up Sansara World 1.0, he also blew up Edgar's dream of following in Sansara Sage's footsteps and venturing outside Anfang.
The revelation that the space-element runes crafted by Sansara Sage were merely tools for exploring the demonic plane left Eren astounded. It was clear that Lin Lehan possessed a visionary mind that often surpassed his own understanding of his creations.
Maya, having Eren finally being able to decrypt the runes in their entirety, finally shared the true legacy of Lin Lehan and the purpose of Sansara World 2.0. Mastery of the space-element runes was an essential prerequisite for traversing the ethereal plane as per Sansara Sage's standards, and only now that Eren possessed this qualification could he be entrusted with this knowledge.
Eager to explore the gluttony plane, Eren's enthusiasm was dampened when Maya informed him that, while he was qualified to learn about these matters, he was not yet qualified to venture into the demonic plane itself.
Maya emphasized that achieving the status of a Master ranker was the minimum requirement before even considering setting foot in the treacherous realm. Without this rank, Eren would have little chance of successfully reaching the neighboring worlds beyond Anfang.
With Maya's explanation, another piece of the puzzle fell into place for Eren. He now understood why Alephee had urged him to achieve Master rank before embarking on his journey outside Anfang. Alephee had shared a similar understanding, but Eren had approached her prematurely, lacking the necessary preparations to comprehend the depths of her explanation.
Eren's mind raced with newfound insights as he pondered the connections between the divine planes and his own experiences. If Maya's words held true, then the denizens of Echidna must possess a similar method for bringing their own kind to Anfang.
This revelation led Eren to reflect on his encounters within the Oni Dungeon, a separate dimension infused with its own set of Nature Laws, capable of supporting a portal to one of the divine planes associated with their divine entity.
Speculating that the Oni Dungeon could serve as a pathway to a divine plane, Eren surmised that the cooperation between the monsters in the dungeon and those from Echidna facilitated stable travel between the realms.
Little did Eren know that a person named Bisha had been sent by priest Rok Jahar to investigate the Oni Dungeon in Anfang years ago, only to become trapped within the divine plane, unable to step foot in Anfang till this point.
Surveying the primitive state of Sansara World 2.0, Eren began to understand why its construction had remained incomplete. The raw and primal Nature Laws infused into this separate dimension would establish a more stable connection with the demonic plane when the portal was eventually opened within it.
As this dimension existed outside the confines of Anfang, the world-encompassing array would not impede the portal's function.
"I… I need to be quick."
Realizing the urgency of his situation, Eren murmured to himself about the need to achieve the Master Rank swiftly. He understood that he had only a year to accomplish this goal, or else he would face a multitude of challenges and complications.
AN: Oni Dungeon was introduced in chapter 441. Rok Jahar and Bisha were mentioned in chapter 743.
