I look at him.
"This dimension...? What do you mean? Are there other..."
"Yes, they are other dimensions."
"How did they get here?"
He shakes his head.
"No one knows. It just showed up one day.
When it was found that you could cultivate electricity from it, it was multiplied scientifically and planted here."
I lapse into silence.
No wonder this floor is 'nonexistent'.
But...
How does he know this?
As if reading my mind, he answers.
