Shell

Right after I said this, there was another tremble that shook the castle.

But this time, it didn't seem to be as strong.

Only that was because of the place that we were currently in.

This castle that was the first castle to be floating was attached to something that caused it to float. And that thing that it was attached to was actually the thing that had created this Castle in the Sky.

Though why it had done that…it was hard to tell.

The only thing that mattered was that whatever it was that had created this place was the one that was responsible for the tremors that shook the castle.

If I had to guess, it was most likely the Boss Monster of this dungeon.

The tremors seemed to be getting stronger and we could hear the sounds of something breaking.
