After discovering the magic circle to the fourth floor, we thoroughly searched around the third floor.
However, we never saw the shadow or shape of Zenith.

We've arrived at the fourth floor.
The instant we came out of the teleport magic circle, at a glance, the surroundings had undergone a complete change from previous floors.
I have a recollection of those stone constructed walls.
As I thought, it's similar to the ruins where the teleport magic circle was.
I wonder if the same type of ruin ended up becoming a labyrinth.
