The entire third floor of the tower was indeed a large mage's laboratory, just as the female zombie embedded in the bed had said.
In the center of the laboratory floor, a pair of concentric circles was drawn, and within these concentric circles, a hexagram was formed by overlapping two triangles.
Bartlett knew that, in the Magic Empire's past, mages used the hexagram as the foundation for drawing arrays and guiding magic power. This is the most fundamental distinguishing mark between the old and new generations of mages.
Similarly, a hexagram and a pair of concentric circles were painted on the ceiling of the laboratory. However, the hexagram on the top was exceptionally large, occupying almost the entire ceiling and enclosing the concentric circles within it.
Apart from that, countless differently shaped magical symbols were carved inside and outside the hexagram. They flickered slowly, like breathing, and continued even though their master had long since disappeared.
