The Wrecking Dawn

Knights of the Wrecking Dawn (also known as the Wrecking Dawn, the Dawn, or the Western Alliance) are a major antagonist faction behind the collapse of the United States, notoriously responsible for the Dark Ages. 
The group was formed by the U.S. militia units in California, Washington, Orgeon, Navada, Hawaii, Alaska, Idaho, Colorado, Montana, Arizona, Utah, New Mexico, Texas, and Wyoming who rebelled against the U.S. government. It is led by the Witness, and Sinn Mercer. It is strongly built on the foundations of Santanic Luciferians, Occultists and the persecution of Christianity and other minority religions such as Jews and Islam.
They are in a long-term battle against the United States armed forces, seeking to bring about anarchy, and deposing the U.S. president. Their true purpose is destroying the Federal Government in order to establish an totalitarian nation, creating a mass chaos in the process.
