Ningxia

About Ningxia
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.

It is home to master Hailong Zalo, a friend of the Vector's, and some of his followers Lee and Feng.
