About Ningxia Edit
Ningxia is portrayed as remnant of Asian cultures post-shattering. The native characters are Chinese, although many of the structures including what the episode title refers to as "the great wall" has more east-Asian designs.
Ningxia is a neutral block whose economy is based around the mining of one of the few quarries in Skyland. It has a contract with the Sphere for half of the contents mined out, but the treaty is tenuous.
