Shang Mu is one of the Three Major Kingdoms of Avalice (alongside Shang Tu and Shuigang) and is ruled by Mayor Zao, whose propaganda covers the streets. Shang Mu first began as a modest port city, but thanks to Zao's Administration, the city grew into a sprawling metropolis, thanks to Zao's Administration, making the rest of Avalice look like the Stone Age. There are strong implications that Zao had gained his position of power through means that are less-than-democratic, such as bribery or rigging the election. However, his cleverness may also be the reason why Shang Mu has grown into the most advanced nation on Avalice. In the two years after Lord Brevon's defeat, Shang Mu found itself under the protection of Captain Kalaw, who is also the champion of the city's Battlesphere.
