Billions.
This is a space made up of books.
Aside from books, all there is are books.
A true mountain of books and ocean of knowledge.
Only in the very center, there is an antiquated desk.
A golden-haired figure sits there, casually flipping through the books she just borrowed, thoroughly engrossed; it is the long-lost Hera.
Her condition seems quite good.
The last time she disappeared at dusk, she was indeed about to be lost, but eventually, she made it through, as if some external force intervened.
When she woke up, she found herself in this place.
An extra-dimensional space opened by Supreme Power.
From the sheer number of books, it is evident.
The owner can only be one person.
Sauron!
Which means her father.
This might be where Sauron conducts his daily research and study.
Now the person is gone, leaving only the mountain of books.
After staying here for hundreds of years.
Hera's injuries recovered, and her Supreme Realm stabilized.
