Shanxi

Shanxi is a Human Systems Alliance colony located near the Shanxi-Theta Relay. It is probably named for either Shanxi (山西省) or Shaanxi (陕西省), which are both historically and culturally important provinces of China. Besides being the jumping off point for local traffic, Shanxi is notable for its involvement in the First Contact War of 2157. It was the site of several battles between the Systems Alliance and the Turian Hierarchy.

The colony was attacked by the Turians during the First Contact War, and was occupated whilst the Turians searched for the relic, which was hidden in a cave system on the planet after the researchers ship has crashed on the planet.
