The Zebub Mantra
"So long as people have a place they can go back to, that alone can grant them peace."
An idea that originated among illegal workers living in the Zebub region near the border.
A city was later built in the Zebub region for war orphans and roadside dwellers: those with nowhere to go back to.
This was the origin of the Last Stop City of Zebub.

Last Stop City of Zebub
Zebub's construction was conducted by the state, with residence standards that favored the aforementioned.
Its citizens were loaned money, distributed food for free, and enjoyed splendorous housing.
The funds for this initially came from the state's budget, but it soon caught the eye of the wealthy and charities, who built up an administration with their contributions.
Yet some denied that Zebub existed. In truth, few paid notice to Zebub. No one spoke of it.
When such a paradise appears on earth, people avert their eyes from it.
Zebub indeed exists. But whether it is paradise, who can say.

Child Laundering
Some lived their whole lives in Zebub, and some left in a few years' time. Some children were adopted into other cities.
One thing is certain, and that is the many rumors that claimed Zebub's children were obedient and honest.
However, there is another detail that cannot go unmentioned: that the children of Zebub do not retain their prior memories.
Where and how did I live before coming to Zebub? All struggle to remember, but cannot.
This arose suspicion of child laundering: that the city of Zebub was being used as a way to obscure a child's identity.
The big newspapers and magazines reported on this, but soon went silent. Presently, next to no one remembers it.
If all things have merit, perhaps that with the least merit of all is the truth.
