Golden inner world

"Where is this?" The bookworm couldn't help saying out loud.

The only thing that replied to it was the echo that came from its voice spreading through this seemingly empty space. 

With the way that its voice echoed, it was as if it was the only thing that was here.

But this was strange since this was the inner world of the person that had attacked him.

It shouldn't be empty like this.

Even if it wasn't as wide and open as the other inner worlds that it had attacked before, it shouldn't be completely empty like this. After all, the inner world was a representation of one's mind, so it shouldn't have been empty like this.

Every single person had something that would represent their mind, so it was impossible for this inner world to be empty like this.

That was unless that person was completely empty to begin with.

In that case…was the person that attacked it just a puppet or was it a corpse that was being controlled by someone?
