From a certain point in time, all new members entering Eme-an were placed under my guidance, and it was my responsibility to gradually unveil the superficial world's mysteries to them. Historians tend to pinpoint exact dates for events, but life is a river of countless interconnected fragments. Even I cannot say exactly when this unwritten "tradition" began. From this perspective, I might be considered the mentor of Eme-an's new members.
I compile everyone's files and have always been willing to take on this task.
Nanna, Nanna, Nanna... Whenever the children of Eme-an feel fear or confusion, the first name they instinctively call out is "Nanna," which fills me with great honor.
More fortunately, I possess the knowledge and strength necessary to fulfill this role.

"The Babel Tower will fall, will fall, it's about to fall..." This is an ancient nursery rhyme from Obed, and no one knows why someone would curse this magnificent tower or why this simple tune has persisted through the ages. For centuries, this ominous song was dismissed as nonsense, but when Director Cosmos took office, it finally became a reality.
As history advances inexorably, humanity is on the brink of the space age. Members of Eme-an reached a consensus early on: when humanity witnesses the full view of the planet beneath their feet, we must retreat entirely into the shadows of history, along with the Babel Tower and the Library of Babel.
Our fellow earthmen believed the ground beneath them was solid as a rock, but in reality, it is a lonely boat sailing on a fine thread over an abyss, and we hold the rudder to some extent. As the Babel Tower fades into obscurity, we must be prepared to eliminate all uncontrollable variables, maintaining the stability of the world line to the greatest extent possible.
Cosmos entrusted this task to me, likely because I have witnessed more history than anyone else in Eme-an, making me the most suitable to perform this historical surgery.
I devised a grand blueprint: systematically replace public domain information, re-edit records in public archives, subtly influence key individuals to alter their memories and relationships, and write new explanations for various relics. Eme-an meticulously filters out people and information related to the Babel Tower, striving to eliminate potential contradictions that may arise after its disappearance.
I do not see this as a deception. Whether the Babel Tower exists or not, humans interpret the universe they see according to their own wisdom. If a new narrative system can completely eliminate the concept of the Babel Tower and remain entirely self-consistent, then it becomes true history, just as non-Euclidean geometry denies the fifth postulate and gives rise to a whole new mathematical system.

Many of my friends have disappeared from my world, either missing or presumed dead.
"Madman" Tasny is a particularly special one. He left me a long time ago, but his memory remains as vivid as yesterday.
Many years ago, Tasny and his wife embarked on a journey of no return. For others, this would be seen as a solemn and glorious event, but their demeanor was more like children excited to visit an amusement park.
I never expected Tasny to return, let alone with two infants.
When I saw him again, he looked terribly haggard. Besides the sleeping twin babies in swaddling clothes, he brought back Sally.
He asked me to take care of his children and Sally. Tasny told me that these children, born in the library, were like floating balloons; until they had enough weight to ground themselves, I had to be the tether keeping them from drifting away.
I didn't bother trying to understand his "mad talk." Experience had taught me that it was pointless to ask.
But when I asked about his wife, Tasny shook his head frantically, his expression a mix of laughter and tears: "She is nearing the end, nearing the end, nearing the end..."
"What do you mean by the end? Has she found—"
"No, no, no, her path does not lead to our end." Tasny waved his hand repeatedly. "You know there are anomalies even in the library? Anomalies within Anomalies, haha! Her end is an anomaly within an anomaly! But these two children—these two children—are innocent!
They have inherited our blood, and they are bound to follow in our footsteps!" he said, wiping tears from his eyes.
"If you want the children to stay away from anomalies and the Secret Alliance, I can send them back to the mortal world. I promise they will grow up healthy," I offered.
"You can't do that. They are miracles born in the library; their talent surpasses what you and I can comprehend." Tasny grinned, "I know, I know, I know… part of the library has found a new form of existence in them, just like their mother. I struggled to bring them and Sally back... Oh, you must keep this a secret from them, okay? When they set out to follow in our footsteps, they will think they are following me, but in reality, they are searching for their mother—this must also be kept secret, okay?"
Those were the last words "Madman" Tasny spoke to me. After that, I went on a mission, and when I returned, Tasny was no longer in the Babel Tower. No one knew where he went, and no records could trace his whereabouts.

Immortality is not a beautiful thing.
It is more like a soft noose, a sweet poison, but one day, it will reveal its cold and deadly true nature.
I say this because I have witnessed true eternity.
And it turned me into a small fragment of itself.
To be honest, I don't remember much of the specifics.
I only recall a red wilderness and the moon hovering above it.
Then, the moon opened its single eye.
My memory seems to begin there, with everything before and after dissolving into a fog of nothingness.
It must have been some sort of anomaly. I spent a lot of effort searching through the archives of Eme-an and C.A.V.E. but found nothing. From the time of Elish to the present, there has been no record resembling it.
Such cases are not uncommon, for small-scale anomalies that only appear to a single witness. But as the years passed, another part of my memory began to surface, gradually becoming clearer.
I remembered the eerie lunar phases that swept across the moon's surface as if it were blinking. Around that time, my body began to undergo the same cyclical changes, making me realize that I had become part of that indescribable "eternity", allowing me to linger in the human world for a long time.
As those who lived in the same era as me gradually passed away, I found myself increasingly isolated in history, and the hope of uncovering the truth grew more distant.
But I have a premonition that the one-eyed moon will one day gaze upon me again from above the wilderness, and that will be the day the noose tightens and the poison takes effect.
