La Gias

La Gias is a subterranean world contained deep within the Earth. A vast place, it sports multiple nations and a large populace. Developing independent of the surface world, La Gias is a place where technology and mysticism have combined into a unique whole. It is here that the Masōki and the Masō Kishin machines are created; their armor material (Orichalconium) is unique to La Gias. Interaction between the surface world and La Gias is usually kept to a minimum, but surface humans such as Masaki Andoh, who is summoned to La Gias, as well as La Gias denizens, like Shu Shirakawa, have traveled to the surface on their own.
