South Continent, Cerryti Empire.
Hidden deep underground, there lies a dark palace that symbolizes absolute power.
This prehistoric underground metropolis, surrounded by darkness, yet meticulously mimicked by magic devices casting a pale light as if from a blood moon; the broad and empty streets are lined with buildings constructed of dark stone, monumental and robust. The silhouettes outline ancient artistry, quietly situated inside this dark city, encrusted with the dust of infinite time.
At the edge of the underground City-State emanates a mysterious, sinister vibe of powerful magic. A humongous castle stands erect, the exterior walls made of natural obsidian, inlaid with icy silver edges and transparent medieval-style red crystal carvings.
