Deep in the Chaos Sea.
A large Empire iron cargo ship was slowly sailing along a route towards the Ark Kingdom.
A young sailor wiped the sweat off his forehead, put down the cleaning bucket, and curiously gazed at the surrounding scenery.
There was no 'sea surface' around.
As far as the eye could see, the entire world was a gigantic, indescribable fruit tree.
The fruits it bore were massive books, as large as mountains, with old, worn covers. The ripened fruits remained spread open.
The iron cargo ship was traveling on the pages of a black leather book; the sound of flipping pages was audible, as the ship moved from one page to another.
Many oddly-shaped little creatures were frolicking on the text surface of the pages. The young man lowered his head and noticed that only where the ship's hull touched the pages did a wave-like texture appear.
