According to legend, the New Yogo Empire was founded by the hero Torugaru after he defeated a water demon with the aid of eight warriors. He became the first Mikado and established the New Yogo Empire alongside Kainan Nanai, the first Master Star Reader.
The name "Yogo" derives from the name of the country of Yogo, where the Yogoese people originally came from. The name "Yogo" means "land blessed by Ten no Kami". Colloquially, the nation of the New Yogo Empire is known as "Yogo" in reference to the country and the people who founded it.
The population of New Yogo consists mostly of the Yogo people, who eventually colonized the Nayoro Peninsula. The Yogoese people variously live in large cities or in farmlands. The people revere the Mikado and the Imperial family as divinities chosen by Ten no Kami, the supreme god of the Yogoese. As such, they respect the belief that commoners cannot directly gaze at the Mikado or members of his family.
The indigenous population, the Yaku people, continue to reside on the Nayoro Peninsula, though largely away from urban centres in smaller villages in the countryside. Unlike the Yogoese, the Yaku people tend to believe in the spirits of nature, indicated by the abilities of magic weavers to connect between the material world of Sagu and the spirit world of Nayug.
The land occupied by New Yogo has a temperate climate, with four visible seasons. The land is fertile, allowing for lush vegetation to grow and agriculture to thrive.
