An ancient Archaean warrior and his banner.
The Old Ones|
The Archaeans were a hyper-advanced race of beings who once ruled much of the galaxy. According to Gruekiller, they came from beyond the Milky Way, colonizing our galaxy more than three billion years ago. Their empire was said to have lasted a billion years, its rule supported by an army of hundreds or thousands of power armor suits. After the mysterious demise of their empire two billion years ago, all of these suits were destroyed with the exception of one, which eventually found its way to Earth. 
In spite of their great antiquity, some legends and knowledge of the Archaeans persist to the present. Archaeologists have spent many decades seeking to learn more, but much information about the Archaeans remains a mystery.
