A region consisting of plains and an extensive forest, where the investigation team established their first base. It is located far from the capital of the Aladissian Empire, and scattered throughout the area are research facilities of the alchemists from that time, such as the “Arbor Botanical Garden” and the “8th Imperial Laboratory.”

The ground has sunk, leading to the proliferation of mushrooms and fungi, which grow larger as one descends deeper. In this region, local inhabitants of Aladiss still reside, including a settlement of the demihuman Welleks. Within the Welleks’ settlement lies the “Preces Cathedral,” a place of worship, as well as the ruins of a large school known as "Hermea Academy."

Once a major industrial region during the Aladissian Empire era, the area is now filled with the ruins of a once-thriving city. At the center, a tree-like structure covered in metal stands along with a “Commercial District” that includes a station and the “Mana Transposing Furnace,” which once supported the daily life of Aladiss through the study of mana, still remains.
