Yin (Formerly Earth)

The earth was forever changed when the moonwalkers returned to earth. Their displeasure with the state of humanity caused them to obliterate human life and attempt to use human DNA to enhance their own existence. However, the moonwalkers were not ready to pay the price of exchanging some of their biological gifts at the price of the long human life cycle.   Thousands of years later and neither moon walker nor human exist. These new humanoid beings share ancestry and DNA from both races but remember neither. Having started over on the planet once called earth, the people of Yin have created their own history.   From the ashes, blood, and tears of that history, 3 empires have arisen. After years of war, the three empires settled on a compact to keep the peace, but with the lack of communication, purposeful misinformation, and political manipulation how long will that peace hold? And what of the lost ancestry of the people of Yin?
