The Shang have a serious chip on their shoulders when it comes to Earthborn humanity in the Jack of Harts universe. They don’t trust us. They don’t like us. And they do not want to see us expand into the galaxy. They want us controlled and docile at worst, and relegated back to Earth at best. They are Not Amused that Aneerin made Contact with us and helped us expand. Not Amused at all. They never actually had an intention to kill all of us, you understand, but they decapitated the American government in an effort to make us surrender without a fight. They did not want a war. And they did not attack us from their point of view. They were defending themselves from us. We are the monsters under the bed. We ARE the primary antagonist of THEIR story.
