"Damn… this could be called the ultimate hidden reward of the Sansara World."
Eren mumbled to himself as he flipped through the memories of the leader of all the elven scions who had infiltrated the event. This was why he was targeting these infiltrators in the first place.
The Elven royal scions and their lackeys were not the only ones infiltrating this event. The senior rankers of the kingdom of Layos had also entered the Sansara World so that they could extract something from it.
Through the memories of his recent kill, Eren realized that the Sansara World was hiding a special place inside it. The kingdom of Layos had been trying to get to this place and steal something valuable ever since it got into conflict with the kingdom of Layos.
This place offered access to the lost path of magic. This path of magic was something Eren was very familiar with at this point.
The butcher licked his lips and smiled wickedly as he thought of using the infiltrators' plan for his own gains. He couldn't help feeling excited at the mere thought of getting his hands on this reward.
Eren thought perhaps he should kill these elven bastards as gently as possible from now on to thank them.
After all… he had a chance to get another Sin Series mark because of them.

Eren learned why the kingdom of Layos had hired Midnight Moon as a distraction. And why it had sneaked in so many prominent rankers within the kingdom of Edinburgh in the first place.
The Delva Gorge incident.
Attack on Healers' Nirvana.
Also, in Eren's past timeline, cultists attacked Silvermoon and killed Arizihana Agnoth.
Everything revolves around this special place hidden within the Sansara World.
***
The Delva Gorge incident saw the cultists from Midnight Moon escape the kingdom of Edinburgh's clutches. These cultists were guided by the royal scions of Layos. They had been using the Midnight Moon as their arms and legs to facilitate the infiltration of prominent rankers from Layos.
The rankers who escaped from Delva Gorge attacked Healers' Nirvana. This was because the guild was led by Jiana Jihang.
Jiana Jihang was the daughter of the two prominent rankers who had settled into the kingdom of Edinburgh after their exit from the kingdom of Layos. Jiana's father was part of the royal family of Layos. So he had a lot of followers when he traveled to the kingdom of Edinburgh.
Jaina's father moved to Edinburgh because the city was prepared to shield him from the royal feud between his cousins at the time. The kingdom kept its promise and allowed Jiana's parents to prosper. In addition, they played a huge role in Edinburgh's affairs.
Jiana's parents helped the kingdom of Edinburgh in exchange for sheltering them and completing all the tasks they had been assigned. They then left everything to Jiana before trying to break into the Sage ranks.
Jiana was hated by the royal family of Layos because she was the daughter of Layos' supposed traitors. The hate was passed down to the current generation's royal scions. Most of them didn't even know why they were told to target Jiana's guild in the first place. They just followed up on their orders and attacked Healers' Nirvana with all their might.
Layos' royal family did not only target Jiana out of hate. Jiana's parents were very respected among the elf community in the kingdom of Edinburgh. According to the kingdom of Layos, Jiana's parents were shown how to get to the special place hidden within the Sansara World through an entrance in Silvermoon.
The royalty of Layos wanted Jiana's help in finding the hidden entrance. Even if she didn't know about such an entrance, she could always look for clues in the stuff her parents left behind for her.
Almost everyone in the upper echelon of both kingdoms knew how Jiana was as a ranker. She was a tough nut to crack. But she had her weaknesses when it came to her guild members. So her guild could be targeted to force her into doing what they wanted from her.
Sadly for the kingdom of Layos, Jiana just dissolved her guild and assimilated into the White Raven guild. And Eren just fucked everybody who showed even remotely ill intentions towards his city and his guild. Jiana didn't have a weakness the Layos royalty could exploit anymore.
Layos' rankers and royal scions who had infiltrated the kingdom of Edinburgh attended the graduation instead. They thanked their stars for arranging such an event for them to enter the Sansara World.
The infiltrators gave up on targeting Jiana and focused on killing the real participants in the event. All so that they could take their place using the elven masks and enter in their stead. The alternate plan was a huge success.
Even cultist organizations like the Beast Bloods had a vague knowledge of the hidden entrance, which opened inside the city of Silvermoon. It just didn't know for sure where it led or what the place had to offer.
But Beast Bloods was certain that the place had something to do with unlocking a lost path of magic that had been banned from Anfang for a very long time. Because of that, it gave a spiked potion recipe to the city protector at the time, Arizihana Agnoth. It then attacked the city of Silvermoon in Eren's past timeline.
The Beast Bloods were determined to find the entrance to this special place in the city of Silvermoon. That's why it had set up a secret base there. The same secret base that Eren had purged and got JJ Edgar's diary from.
Even JJ Edgar was looking for a way to get to the special place as well. That's why he used the Beast Bloods' hideout to perform surveillance. The Beast Bloods didn't know what had happened to Edgar. However, they were unable to locate him after some time. And he never came back to retrieve his belongings. Therefore, they remodeled his office inside the cultist base and scrapped most of his stuff, including his journal.
A lot of time would pass before Eren came to possess his journal at the cultist base near the city of Silvermoon in his current timeline.

AN: Chapter 655 foreshadows the city of Silvermoon being attacked by cultists to find the entrance to the special place.
