The Milky Way Sea divides the Nanshan Continent into two parts: east and north, west and south.
The Great Tang in the Eastern Lands, the Qiang Di flute of the Northern Desert, the outstanding heroes of the Southern Domain, the totems of the Western Desert.
The Great Tang in the Eastern Lands is known for its power, the Northern Desert for its intrepid barbarians, the Southern Domain for its many outstanding heroes. As for the Western Desert, well, it is known as the Barbarian West with its Western Devils. In fact, its name actually represents madness.
Chaos is the normal state of affairs in the Western Desert. There are no Sects there, only countless Tribes. Some Tribes formed alliances, and then larger coalitions of power.
Because of the infertility of the land, and the scarcity of resources, as well as the deplorable condition of the environment, the Western Desert Cultivators lived a life of merciless killing. They cultivated the power of their totems, longing for the day when they would take over the Southern Domain.
The two great wars between the west and the south had resulted in great sealing spells that separated the two powers. The regions left unsealed became the Black Lands. They belonged to the Southern Domain as well as the Western Desert. As such, there was more freedom there, as well as more ruthlessness.
Some areas there were infertile, but some were the opposite, creating a polarizing effect. Killing occurred at the slightest pretext, causing the land to constantly be filled with the reek of blood.
