The United Colonies of Mankind, commonly known as the UCM are the result of the small section of humanity that managed to escape the Cradle Worlds during the Scourge Invasion. It is a rich melting pot of cultures that had to quickly adapt to live together on the Frontier worlds. They have planned and waited for their chance to retake the Cradle Worlds in an endeavour they call the Reconquest. Now the Reconquest has reached Earth, the fate of humanity will be decided very soon. Will Mankind retake Earth and have it's home back, or is humanity destined to be nothing but slaves to the Scourge, a ready supply of fresh hosts. A result that could only be described as mankinds worst nightmare.
