There was an entity/creature who controlled the imagination in one universe.

The nickname for the entity/creature is "Imagune" was the nickname for the entity that the humans had made

The humans there don't know the real name of the creature/entity

So they made songs in the name of "Imagune"

Praises, prayers & the well-being of their home

The "Imagune" Is the one who manages the imagination but the "Imagune" is no longer alive for the one who killed the "Imagune" is still unknown but the humans there now

That something has made its universe by inheriting the power of the "Imagune" and now lives in that imaginary universe

***

It is known that they sacrifice one person every 100 years

So the one who is sacrificed will see the one who manages the imagination

But tho as I said they're dead

The people there can't know such luxury as imagination so

They die a void less death

But

Ollein is the storyteller and the kids love hearing the story that Ollein told in the books

The person who will be sacrificed this year is going to Ollein

The system of the government is like a kingdom because there is no imagination

And they rely on the old people's knowledge

The one who manages the world now is named after "Imagune"

The governor has decided that Ollein has to die because the governor is suspicious of Ollein

Because he reads the books that the previous generation has made and keeps them in the best condition he can

So the system has stayed the same over the years.
