Where are all the warriors live, Necromancers prowl, & beautiness lives! And a lot of bamboo grow. MooShu is ruled by the Emperor, who is considered the Child of the Spirit of the Sun, and is served by legions of loyal Samoorai. The Cows of MooShu form the ruling class made up warriors, princes and master artisans. They are attended by Goat bureaucrats and ministers, while the Sheep and Pig peasants humbly work the land. The people of MooShu are notoriously secretive and suspicious of outsiders; foreign ships are only allowed to dock in one port, the resplendent city of Hamamitsu, without special permission, and only the mysterious Wizards have ever walked in the Imperial Skyway or visited the Imperial Palace.
