In the southwest of Chu City, there was a continuous mountain range, called "Changming Mountain". Surrounded by green forests in the mountains and a quiet environment, it was a rare resort within the federal city walls. Many vacation villas of dignitaries and nobles were built here, hidden among the dense forests, and winding paths led to seclusion.
The only public facility was the Oriental Sanatorium on the top of the main peak. This sanatorium had a history of over a hundred years. It was a medical facility built at the same time as Ydalir, the city of adventurers. Originally, this was the recuperation villa of the first-generation Adventurer City governor.
Later, the general donated his villa and converted it into this sanatorium. Today, it was run by the First Military Region Hospital in Chu City. It basically accommodates officers who were seriously injured on the battlefield.
